environmental impact of tropical cyclone eloise in mozambique pdf

Emergency Response to Cyclone Idai in Mozambique, Malawi and Zimbabwe - SAF191 7 1. Eloise is likely to intensify once it re-enters the Mozambique Channel. d). TC caught between tropical easterlies and mid-latitude westerlies. This strongly affects circula- tion and moisture supply over Southern Africa. forecast ensemble members anticipating recurvature away from the coast. Sofala was the most affected province, with Buzi, Dondo Nhamatanda, and Chibabava districts reporting significant damages to shelters, while Caia, also in Sofala province reported some damages in four of the resettlement sites assessed in the district. When an ocean Rossby wave crest arrives in the southwestern part of the basin, increased SST and local convective rainfall alters the large-scale circulation. An image grab taken from an AFP TV shows people standing among damage in the port city of Beira on January 24, 2021, after Tropical Cyclone Eloise hit Mozambique. Ultimately, better communi-, cation between forecasters and disaster managers could reduce fatalities in the only part of, and Meteo-France Reunion (P. Caroff). Glob Planet Change 100:28–37, Tolman HL, Balasubramaniyan B, Burroughs LD, Chalikov DV, Chao YY, Chen HS, Gerald VM (2002). Clim Dyn. The spatio-temporal links between sea surface temperatures and winds reveal a strong coupling through the precipitation field and ocean dynamics. The quick demise of the Indian Ocean Dipole anomaly in November–December then induces a sudden collapse of anomalous zonal winds over the Pacific Ocean, which leads to the development of El Niño/La Niña. This contributed to the passage of TCs from the SW, Indian Ocean to the Mozambique Channel. Positive SST anomalies in the SW Indian. anomalies (m/s) in section averaged 15–30S with topographic profile. Using 38 years of ERA‐Interim reanalyses, this study examines the flow and associated moisture fluxes induced by ridging South Atlantic Ocean anticyclones over South Africa. However, owing to the high levels of oceanic turbulence, model solutions of the region are highly sensitive to their numerical choices(9,10), stressing the need for observations to confirm these important model results. Climate data was used to characterize historical drought using a Standardized Precipitation and Evapotranspiration Index whilst vegetation anomaly maps were used to demonstrate impacts. Primary data was collected through questionnaires, key informant interviews and field observations while population, climate and hydrological data are also analyzed. Atlantic, Unlike in the Sahelian region rainfall variability in Southern Africa exhibits mainly in- terannual component and no long-term trend. Contrasts between SODA and GODAS reanalysis products reveal the former exhibits higher amplitude annual to inter-annual variability. Tropical cyclone USA 1900-2005 Wealth per capita, population No trend since 1900 Pielke et al. The influence of large-scale circulation patterns on the track and formation of tropical cyclones (TCs) in the Mozambique Channel is investigated in this paper. The daily time series of gauge and satellite rainfall on the southeast coast of Africa, March. Composite analysis also shows that ridging‐induced moisture fluxes affecting South Africa originate from different areas of the surrounding oceans at different times during the evolution of ridging highs. It was found that households, schools and clinics in the study area rely mainly on boreholes for water supply but sometimes rivers supply those living nearby. Heavy rains were promoted by onshore winds between the TC and ridging mid-, latitude anticyclones. Hazardous phenomena are not only located on islands and coasts. Previous studies have found that the tracks and strengths of tropical storms and cyclones are difficult to predict more than a few days ahead. Satellite images captured by National Aeronautics and Space Administration (NASA) show the extent of damages caused by tropical cyclone Eloisa that struck Mozambique's port city Beira on January 23, 2021. SST in the northern Mozambique Channel exceeded 29, d). J Geophys Res 113:D04110. Tropical cyclone formation is influenced by many factors, but the role of warm sea-surface temperatures as the primary source of energy for cyclones is paramountxxvii. Mid-tropospheric cut-off low (COL) pressure systems are linked to severe weather, heavy rainfall and extreme cold conditions over South Africa. The affected districts are Buzi (4,619 households), Dondo (1,230 households), Chibabava (773 households), Caia (66 households), and Nhamatanda (102) all in Sofala province;  Sussundenga (1,695 households)in Manica province; and Maganja da Costa (143 households), Namacurra (62 households), and Nicoadala (65 households) all in Zambezia province. The rainfall forecast of the South African Weather Bureau Eta model shows encouraging results as far the geographical distribution of rainfall is concerned but the rainfall totals were underestimated by some 50%.

Hazards, Nat. A cyclone is a spinning storm caused by a low-pressure area in the atmosphere. Ocean were at odds with the expected Pacific La Nin, While SST are a key part of TC forcing, the atmospheric circulation must offer horizontal, cyclonic vorticity and vertical easterly shear (Gray, the ocean, a warm pool of water propagated slowly westward along 10S consistent with a, formed in or drawn to the Mozambique Channel: Chanda, Dando, Funso, Giovanna, and. Cyclone Yasi destroyed the sugar cane plantations as well as the banana plantations as previously stated. Likewise, about 71% of the variables were at or below incipient level of development. A mixed methods research design was employed using qualitative methods such as content analysis whilst quantitative methods were dominated by time series analysis techniques and online interactive climate platforms such as the Climate Engine. Out of these provinces, The recent 2015/16 event had devastating impacts on water levels, crop yields, livestock herds and rural livelihoods. Key shipping lanes given in (, Derive from ocean reanalysis of daily HYCOM and WAM models, ). Forecast model guidance and TC forecasts were provided by CFS, ECMWF, JTWC, Regression of SOI onto ECMWF 200 hPa winds, ) over the period 1990–2014, reflecting a similar pattern elongated westward. Monthly rainfall totals exceeded 1000 mm along the eastern escarpment of the Northern Province, with 24-hour rainfall greater than 400 mm on 6 and 24 February. There are, twin anticyclonic rotors in the longitudes 30–50E south of Madagascar (30S) and over the. Tropical westerlies increased in the 15°S zone in the first season and model errors were smaller. Paper presented at the ASPRS 2009, annual conference, Baltimore, Maryland, 9–13 March 2009. anticyclonic rotors in the subtropics of both hemispheres. However teleconnections with ENSO seem unstable in time: it leads to stonger and more. Mozambique’s climate ranges from tropical and subtropical in the north and center, to semi-arid steppe with ... such as the 2017 Cyclone Dineo, which destroyed almost 30,000 hectares of crops and ... negatively impact Mozambique’s hydropower production. Research on these factors is abundant; nevertheless, there is a lack of these studies concerning Africa. A Household Vulnerability Index determined variable levels of vulnerability such that different strategies are employed to adapt to drought some of which cause environmental problems. The links between SST modes over the Indian Ocean and the strengthening and weakening of the Mascarene High have been demonstrated. Case studies are presented for TC Dando and Irina, and forecasts of. ) The warm Western Indian Ocean is a major source of moisture for the subcontinent also permitting tropical cyclone genesis. analysis of data assimilation based mesoscale products, to understand processes of atmospheric variability from short to long time scales. side of the Mozambique Channel were affected by five cyclonic flood events. The flow and moisture fluxes are divided into their geostrophic and ageostrophic components. The study area lies in a semi-arid region which regularly experiences climate extremes such as droughts and floods which can reduce the ability of the municipality to supply water. Int J Climatol, Saha S et al (2010) The NCEP climate forecast system reanalysis. related to a subtropical ocean Rossby wave coupled with equatorial zonal winds. A secondary rainfall peak corresponds to the 2011/12 rainfall season when tropical cyclone Dando affected the area (e.g. Operational forecasters. penetration of Irina from 3 to 6 March (Fig. The outbreak of COVID-19 has resulted in a global pandemic, heightening the risk to vulnerable populations, internally displaced people, and people…, Following the recent attacks in Palma sede, the IOM’s DTM team conducted a remote assessment on 15 April 2021 in the displacement location of EPC de…, Following the recent attacks in Palma Sede, DTM teams in Nangade, Mueda, Montpuez, and Pemba districts continue to register significant rise in IDP…, © 2019 Displacement tracking Matrix | Terms & conditions, Mozambique – Flash Report 16 - Tropical Cyclone Eloise (January 2021), Mozambique – Covid-19 Impact Assessment In The Central Region Of Mozambique Round 3 (March 2021), Mozambique – Flash Report - Displaced Families in EPC de Quitunda - Palma Crisis (15 April 2021), Mozambique - Emergency Tracking Tool | Palma Crisis Report - 56 (27 March - 17 April 2021), Mozambique - Emergency Tracking Tool | Palma Crisis Report - 55 (27 March - 16 April 2021), Mozambique - Emergency Tracking Tool | Palma Crisis Report - 54 (27 March - 15 April 2021), Mozambique — Emergency Tracking Tool | Palma Crisis Report — 53 (27 March - 14 April 2021). The 3 March. Based on … Indian Ocean. The discovery of this dipole mode that accounts for about 12% of the sea surface temperature variability in the Indian Ocean—and, in its active years, also causes severe rainfall in eastern Africa and droughts in Indonesia—brightens the prospects for a long-term forecast of rainfall anomalies in the affected countries. However, fruit farmers need the opposite for their over-watered crops. studies on the variability of TC frequency, intensity, and propagation are given in Jury and, studied the landfalling cyclones Domoina and Imboa in 1984, which followed similar paths. Here are some impacts of a tropical cyclone: The rainfall, circulation, and temperature fields surrounding the TCs were studied for, anomalous characteristics. (, The basis of this study is TC tracks, intensity, and forecasts from Meteo-France Reunion in, January–March 2012. predicted landfall of Irina in southern Mozambique on 3 March (Fig. The moisture fluxes have a northeastern orientation on land, following the geometry of the eastern coast. Int J Climatol 34:3604–3615. Its influence on the wider region is determined As a result of the impact of Tropical Cyclone Eloise, 8,755 families had their tents and shelters destroyed/partially destroyed. Just to the northeast of Madagascar. The landfall of Tropical Cyclone Eloise in the night of 23 January 2021 and Tropical Storm Chalane on 30 December 2020 has affected Sofala, Manica, the southern part of Zambezia, Inhambane, and Gaza provinces. Join ResearchGate to find the people and research you need to help your work. Some more than others. A nearly perpendicular flow of moist air over the eastern escarpment of South Africa was responsible for the exceptionally heavy rainfall over these areas. Globally, subtropical circulation in the lower troposphere is characterized by anticyclones over the oceans. We investigated the nature of the drought hazard; its impacts, including vulnerability of rural communities in Mopani District and adaptation strategies they have employed to cope with drought. Tropical Cyclone "Eloise" is moving WSW over the Mozambique Channel, towards the central coast of Mozambique. As a result of the impact of Tropical Cyclone Eloise, 8,755 families had their tents and shelters destroyed/partially destroyed. The study recommends the need for government and municipalities to invest in water reticulation systems in the long term whilst providing water to affected rural communities through water tankers, drilling more boreholes and maintenance of existing ones. Here, the models under-estimated rainfall associated, a) shows TC Irina close to Maputo on 3 Marc, on March 2, 2012, from Meteo-France Arpege model and from, c) consistent with the looping track of a, components. Springer Science+Business Media Dordrecht 2015, Tropical cyclone (TC) activity in the Mozambique Channel from January to. Tropical Cyclone Eloise reached the coast of Mozambique on 23 January, with winds of around 140km/h and gusts of up to 160km/h (category 2 tropical cyclone equivalent). Further, ). Indian Ocean, this zonal circulation extended only to the Mozambique Channel. Following work by Zeke Hausfatherxxviii, we have analysed the probability density of tropical cyclone formation by … Meteorol Atmos Phys 106:149–162, Chang-Seng D, Jury MR (2010b) Tropical cyclones in the SW Indian Ocean. the Congo River Basin in March to May (MAM) and July to September (JAS) seasons. An Agulhas leakage shutdown has been associated with extreme glacial periods(4), whereas, Teleconnections between equatorial African climate and the surrounding circulation are examined using a convective index over Ridging events are associated with about 60% of rainfall days in summer over southern Africa whilst TTTs contribute about 21% summer rainfall days. One important aspect is atmospheric blocking due to the Mascarene High, which leads to anomalous rainfall and temperature events over the subcontinent. This paper attempts a synthesis of new observations and new concepts on how tropical cyclone formation occurs. Severe Tropical Storm Eloise is a current tropical cyclone weakening from land interaction with Madagscar at present. TROPICAL CYCLONE IN MOZAMBIQUE Last Updated 03/22/19 G E O G RA PH IC IN FOR M A T I O N U N I T U S A I D/ DC H A / O F D A. season. However, several variables showed potential as precursors of tropical storms and cyclones, and some of these could be predicted at long lead times. The inclusion of forecasts of these variables as predictors in hybrid statistical–dynamical forecasting systems could potentially extend the time horizon for prediction and early detection of possible tropical storms and cyclones in the region. The associated moisture divergence region is always located ahead of its ageostrophic counterpart, with a local maximum eventually forming in the Mozambique Channel. It was found that nearly half the time there is some form of drought or another in the district mostly linked to the remote El Nino phenomenon. Context: Part of the area affected by Cyclone Eloise was affected by Cyclone Idai in 2019 and Cyclone Chalane in 2020, particularly Sofala and Manica Provinces and parts of Beira City (see map). The death toll may not be known for months, but it is already likely to have run to hundreds and possibly thousands of people. The CFS model handled, the spiral rain band extending east along the coast, in comparison with satellite observa-, tions. Mapped results derive from the KNMI Climate Explorer, Interna-, ) and anomalies in the cyclogenesis zone (, ), but soil moisture deficits caused Botswana maize yields to decline, . In addition to the human and material damage, the earth's low-pressure system flooded some 142,000 hectares of land, threatening biodiversity and food security. During three spells, there were coincident TC pairs: Funso–Ethel (Fig. Tropical cyclone (TC) prediction and impact of warming environment on cyclonic activity are one of the most popular research topics. The 2019 TC season in the Mozambique Channel characterized by TC Idai in March and TC Kenneth afterward in April was used in evaluating how the CTs designated to have TC characteristics played role in the formation and track of the TCs towards their maximum intensity. In the absence of a coherent observing system, studies of the Agulhas have relied heavily on ocean models, which have revealed a possible recent increase in Agulhas leakage(6-8). Sofala was the most affected Despite many worthy observational and numerical modeling studies in recent decades, our understanding of the detailed physical processes associated with the early stages of tropical cyclone formation is still inadequate; operational forecast skill is not very high. The 2000 TC season had an exceptional number of landfalls (Vitart et al. Losses of life and material damage are significant due to strong winds, heavy rains, large swells and storm surges. Cyclone Idai also had significant impacts in neighboring countries Malawi and Zimbabwe. Part 2: structure and impacts at, the event scale. WATER SECURITY IN RURAL LIMPOPO IN A CHANGING CLIMATE: A STUDY OF THE GREATER-GIYANI LOCAL MUNICIPALITY, SOUTH AFRICA. In this study, we review the dynamics of the Mascarene High, its interactions with the ocean, and its impact on weather and climate over Southern Africa. Nearly two years after it was hit by devastating cyclones, debt-ridden Mozambique’s recovery effort is backsliding as it is battered by another powerful tropical storm. 50 free online copies in: instead. Their impact can be devastating. The second event, Cyclone Kenneth, affected 250,000 people and caused 45 casualties. Most of the rainfall occurred during the periods 5-10 February and 22-25 February and in both instances were caused by tropical weather systems that moved from east to west over the subcontinent. Therefore, damages were reported in resettlement sites where people displaced by Cyclone Idai live, with thousands of tents and temporary shelters destroyed, as well as permanent structures such as schools and hospitals. African Sahel, with influence from the Pacific El Niño. J Clim 12:1738–1746, Kanamitsu M, Ebisuzaki W, Woollen J, Yang SK, Hnilo JJ, Fiorino M, Potter GL (2002) NCEP-DOE, AMIP-2 reanalysis. Cyclones which cross the highlands of Madagascar are not well handled by the model, recurving poleward while predictions maintain westward movement due to model resolution, the steep topography, and consequent entrainment of flow around Madagascar. The Province of Manica, more specifically Sussundenga district, also reported some damages after the tropical cyclone, the southern part of Zambezia also reported damages to shelters in resettlement sites. With a tropical cyclone comes loss, destruction and economic break downs. A tropical cyclone can impact the economy, environment and society. These ageostrophic fluxes contribute to the occurrence of rainfall during the ridging process in the region located between Lesotho and Swaziland. The looping. Chang-Seng D, Jury MR (2010a) Tropical cyclones in the SW Indian Ocean. Here we show using a simple forecast model that in addition to this link, a negative phase of the Indian Ocean Dipole anomaly is an efficient predictor of El Niño 14 months before its peak, and similarly, a positive phase in the Indian Ocean Dipole often precedes La Niña. CTs with synoptic features favorable for the development of TC in the Mozambique Channel were noted. included TC Eline that traversed southern Africa all the way to Namibia, claiming, lives and bringing historical flooding to the Limpopo River Valley (Dyson and van, flow over the Mozambique Channel that guided systems onto the plateau. S Afr, Poolman E, Chikoore H, Lucio F (2008) Public benefits of the Severe Weather Forecasting Demonstration, Project in south-eastern Africa. Many of the operational models anticipated a northwest track, whereas Dando, moved more westward. A factor analysis was also conducted to identify the underlying factors that either hindered or promoted flood preparedness. compounded by interaction of the tropical steering flow with a passing mid-latitude trough. Ocean wave heights and sea surface salinity are analyzed from the. Following cyclone Idai, IOM set-up a robust multi-sectoral approach in central Mozambique complemented by the delivery of shelter and housing support, livelihoods, mental health and psychosocial interventions, CCCM and protection. On 29 January 1984, the tropical cyclone Domoina moved over Southern Africa from the Indian Ocean and caused the largest ever floods in parts of Southern Mozambique, Swaziland and South Africa. Understanding the performance and limitations of the UM model in simulating COL characteristics can benefit severe weather forecasting and contribute to disaster risk reduction in South Africa. Regional wind responses to SW Indian Ocean heat anomalies contribute to a 15% change in seasonal rainfall and maize production in South Africa. Part 1: inter-annual variability, and statistical prediction. steering flow from northeast over the Mozambique Channel. Here, using satellite altimetry observations from 1993 to 2009, we show that the mesoscale variability of the Agulhas system, in particular in the Mozambique Channel and south of Madagascar, has intensified. Sea level air pressure, latent heat flux, and predicted daily rainfall. Despite these challenges which are not well documented, it was concluded that most of the rural poor households and institutions in the study area are well adapted to cope with water scarcity in the short term, while being vulnerable in the long term due to population growth and climate change. The landfall of Tropical Cyclone Eloise in the night of 23 January 2021 and previously, the Tropical Storm Chalane on 30 December 2020, have deeply affected Sofala, in particular Buzi area, Manica, the southern part of Zambezia, Inhambane, and Gaza provinces.

It is argued that the down-. EXTREME FLOODS IN SOUTHERN AFRICA CAUSED BY TROPICAL CYCLONE DOMOINA. Tropical cyclones in the Mozambique Channel: January–. Specific humidity at 500 hPa and divergence at 200 hPa were higher than normal several days before the peaks, and these potential precursors were also forecasted with skill up to about 2 weeks in advance. Lessons learnt from this study may be useful to other municipalities across South Africa that are grappling with challenges of water access and supply. Results show that riparian communities are unprepared for flood disasters. Repeated tropical cyclogenesis in the Mozambique Channel according to, ... Consequently, floods have dominated natural hazard damage across the globe (IFRCCS 2019; Kolen and van Gelder 2018;Muhonda et al. This modification of the teleconnection may be related to the Indian Ocean warming through a westward shift of the subsident branch of the anomalous zonal circulation during ENSO and its location over Africa. 2014). Mozambique is currently a net exporter Dando brought coastal flooding to southern Mozambique, Swaziland, and the eastern, affected Madagascar, Mozambique, and South Africa on its winding path. The 2012 season had a warm SW Indian Ocean (cf. J Clim 23:726–742, o, and Atlantic hurricane damages in the United States. surplus convection was thus confined to the east of Africa. Eloise, fuelled by the warm Indian Ocean waters of the Mozambique channel, gained tropical cyclone status with its strength equivalent to a category two storm, the World Meteorological Organisation (WMO), said. The mesoscale Unified Model and ECMWF model (not shown) forecast peak, amounts of 30–50 mm/day to the north of cMorph satellite observations of 100 mm/day, consistent with gauge totals, but spread too widely to the north. The output of the hourly classification of circulation types (CTs), in Africa, south of the equator, using rotated principal component analysis on the T-mode matrix (variable is time series and observation is grid points) of sea level pressure (SLP) from ERA5 reanalysis from 2010 to 2019 was used to investigate the time development of the CTs at a sub-daily scale. doi: Gray WM (1998) The formation of tropical cyclones. They occur during all the above and often result in floods and snowfalls during the winter months, disrupting economic activities and causing extensive damage to infrastructure. The Meteo-France Reunion five-day forecast anticipated inland. Questionnaires were administered among community members whilst key informant interviews were conducted among relevant government and municipal officials. (anomalous flow toward Africa), whilst upper westerly winds weaken over southern Africa (in JAS). © 2008-2021 ResearchGate GmbH. a vigorous increase has preceded shifts towards interglacials(5). techniques for gauge-based analyses of global daily precipitation. Cyclones (and hurricanes) economic damage is well know, but what of the social costs.

Another anomalous wet season that affected the Greater-Giyani Local Municipality coincided with the occurrence of a La Niña event over the equatorial Pacific Ocean during 2011/12. 2009 Tropical cyclone China 1984-2008 GDP No trend Zhang et al. Good agreement is found for sub-surface temperature in the SW Indian Ocean thermocline ridge, with rhythmic fluctuations of 2.5-5 yr period. Tropical cyclone (TC) activity in the Mozambique Channel from January to March 2012 resulted in five landfalls that affected Madagascar and southeastern Africa. Final, Crimp SJ, Mason SJ (1999) The extreme precipitation event of 11. Mozambique. While the Quasi-Biennial Oscillation (Jury, ). As, thermocline deepens to the northeast of Madagascar with an incoming Rossby wave, SSTs, are able to simulate this process and its impacts on tropical convection. The downstream shedding of a vortex from, Madagascar contributed to the variable nature of TC tracks and forecast errors in January–, Southwest Indian Ocean islands and coastal southeastern Africa are vulnerable to tropical, cyclone (TC) impacts. TC Irina formed northeast of Madagascar on February 25, 2012 (cf. The assessment focuses on understanding the extent of damages to shelters and facilities across all 70 existing resettlement sites in Sofala, Manica, and Zambezia Provinces, which were established in the aftermath of Tropical Cyclone Idai in 2019. Bull Am Meteorol Soc 83:1631–1643, Landman WA, Botes S, Goddard L, Shongwe M (2005) Assessing the predictability of extreme rainfall, seasons over southern Africa. Many rural communities of South Africa are living without adequate water supplies mainly due to historical lack of infrastructure and effective water reticulation systems.
