a region of high rainfall in africa

Droughts are becoming more widespread across the Sahel and eastern Africa. only received major rainfall half of the year and dry season the other half. Countries in this region comprise of South Africa, Zimbabwe, Zambia, Swaziland, Namibia, Mozambique, Malawi, Lesotho, Botswana, and Angola. In the last decades droughts have caused hunger and starvation in many part of the Sahel and Ethiopia. The amount of heat from the sun plays a major role in determining climate. Warm all year, distint rainy or dry seasons, at least 20 inches of rain during the summer. In this study, we explore the possible mechanism of opposite ENSO effects on summer rainfall in the JJAS region (northern GHA) and autumn rainfall in the OND region (equatorial GHA). East Africa, consisting of Uganda, Kenya, and Tanzania, straddles the equator. Mouth of the Olifants River (north-west) to the Breede River mouth (south). In consequence, the influence of the sea extends farther inland in Southern Africa. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Summer rainfall in one of the world's most drought-prone regions can now be predicted months or years in advance, climate scientists at the Met Office and the University of Exeter say. Thus, at Port Elizabeth there are six months when temperatures are below 62 °F (17 °C), while at Durban mean monthly temperatures do not fall below 64 °F (18 °C). This region is characterized by rainfall throughout the year, but it is heaviest in summer. Stormwater tanks are also required in built-up areas to slow the volume of water entering the drainage system during a high rainfall event. Rising temperatures, drought and erratic rainfall are making growing coffee harder. The winter months are much rainier than the summer months in Cape Town. The Llanos of Columbia is characterized by mean annual rainfall of 200cm-400cm (near Andes Mountain), mean annual temperature of 22°C, and maximum temperature of 32°C. Marked variations in the rhythm of equatorial climate sometimes occur. The coldest regions of Africa lie in the eastern highlands and southern Africa. More specifically, our objectives are as follows: While the Western Cape has a Mediterranean climate with winter rainfall, most of the country experiences summer rain. The West Africa Sahel region is a semi-arid area that runs from the Atlantic Ocean eastward to Chad, separating the Sahara Desert to the north and the Sudanian Savana to the south. Iquitos (Peru), Akassa and Ocean Island receive 261 cm, 366cm and 213cm of rain per annum respec­tively. While Western Cape gets most of its rainfall in winter, the rest of the country is generally a summer-rainfall region. The climate is humid with a tropical regime. Typically experiencing higher average temperatures, urban areas also frequently have less wind and lower relative humidity; there is too little relevant data from Africa, however, to permit a detailed study of urban climates. A number of factors influence the climate of the African continent. We used rainfall and temperature records between 1987 and 2016 from 46 weather stations across South Africa to calculate annual rainfall seasonality characteristics using two methods. In most of southern Africa, rainfall peaks in the austral summer/boreal winter. At the ITCZ itself, however, precipitation is prolonged and intense as air converges between the maritime and continental air masses and is forced aloft. These northern and southern air masses meet at the intertropical convergence zone (ITCZ). The temporal characteristics of rainfall variability in Africa are examined using departure series for 84 regions of the continent and five larger-scale zones. Climate Information Tool, Monthly Data This tool provides data for any location in Africa, even if no weather station is available.  Most of Africa lies in the tropical or subtropical region. Most of Africa is divided into wet and dry seasons. hourly or sub-hourly, to represent different intensities. In the northern and southern extremities of the continent, there is a dry summer subtropical, or Mediterranean, type of climate. In the desert regions of the Sahara, Namib and Kalahari rainfall often drops to under a hundred cm a year. The region’s climate is mainly influenced by large scale seasonal atmospheric patterns and the warm waters of the tropical Atlantic Ocean. During this time heavy rain falls every day in the afternoon. In response to the increasing climate-related health threats, member states in African region in 2016 adopted the Regional Strategy for Health Security and Emergencies which, along with the International Health Regulations, aims at strengthening countries’ capacities to detect, prevent and response to public health emergencies. The convergence zone moves southward, dipping into Southern Africa. Extreme rainfall in West Africa: A regional modeling ... rainfall extremes in order to provide regional maps of high quantiles of the distributions (typically, 20 to 100 year or higher return period values), thus allowing to estimate these quantiles at nonobserved sites. Near the equator there are two very wet seasons, as the sun passes overhead in spring and fall. The coldest regions of Africa lie in the eastern highlands and southern Africa. The Guineo-Congolian Region is the wettest in West Africa, with average annual rainfall between 2,200 and 5,000 mm. Temperatures are about the same as those in the desert regions. We then explored how these characteristics … Most parts of Africa are warm or hot, but rainfall varies from region to region. A follow-up report that provides a specific focus on the climate of the semi-arid regions of southern Africa is currently under development. Name the 3 most important rainfall regions in South Africa. First, most of the continent—which extends from 35° S to about 37° N latitude—lies within the tropics. The rest of the year is dry.
