Topic > Temperature and climate variability - 875

Between 1979 and 2010 there was a notable increase in temperature trends across the African continent. These temperature trends are measured with Microwave Sounding Units (MSU), Remote Sensing Systems (RSS), and the University of Alabama at Huntsville datasets. Africa is a rather unique continent in that it straddles the equator, so the upper half of Africa is in the Northern Hemisphere, while the lower half of Africa is in the Southern Hemisphere. This has a direct effect on temperature and rainfall patterns in Africa, this is evident as the northern half of Africa is mainly arid and desert regions, while the southern part of Africa consists of savannas and rainforests. It is because of the large differences in climate between the northern and southern parts of Africa, that I will look at the climate and temperature variations in the northern, southern, eastern and western parts of Africa separately, to try to understand the variations across the whole of Africa. Africa. First, I will look at temperature trends in the southern hemisphere of Africa. The southern hemisphere of Africa receives more rainfall and, therefore, has much more natural vegetation and greenery. Normal temperatures in Southern Africa show summer highs and winter lows, however, rainfall here is unpredictable and erratic. Twenty-three climate stations were used to help make predictions about the variability of the South African climate. At the end of the experiment, the average seasonal temperatures were compared and it was found that the temperature trend is not constant throughout the year, with autumn showing a maximum trend and spring a minimum trend. It was also found that temperature trends, in general, if...... half of the article ......regionsWorks Cited• Kruger, A.C. and Shongwe, S. (2004), Temperature trends in South Africa : 1960– 2003.
