Winter temperatures were 10–17°C lower than today in Eurasia with a more significant decrease in northern regions. In Africa, winter temperature was 10–15°C lower than present in the south, while it was only reduced by 0–3°C in the tropical zone. Comparison of palaeoclimate ...
The most significant climatic change that has occurred has been a long-term reduction in rainfall in the semi-arid regions of West Africa. This was on the order of 20 to 40% in parts of the Sahel. There have been 3 decades of protracted aridity. Nearly all of Africa has been affected...
There are five general climate regions:tropical (low latitude), dry, mid-latitude, high latitude, and highland. Dry and highland cli- mates occur at several different latitudes. Within the five regions, there are variations that geographers divide into smaller zones. What are the 10 climate zones?
As the meridional surface temperature gradient increased, boundaries between climatic zones strengthened, leading to increased aridification of mid-latitude continental regions in Australia, Africa and North and South America, enhancing the development of grasslands and stimulating the evolution of grazing ...
). After removing the signal of MCOLR, the correlation between ATCOI during SO and East Asian winter precipitation becomes insignificant, particularly in the regions south of the Yangtze River, the Korean Peninsula, and southern Japan (Fig. ...
A brief review of climatic changes over the last 800 000 years in southern Africa is presented. The greatest emphasis is placed on those changes occurring during the Holocene and the period of meteorological record. Twentieth-century rainfall variations and their spatial manifestations are examined, ...

We examined the influences of temperature and precipitation anomalies on interannual variation in human WNV cases in three regions of the United States. There were consistent positive influences of winter temperatures, weaker and more variable positive effects of spring and summer temperatures, and ...
To review impacts of rainfall variability on cereal production To discuss the role of climatic forecasting in the current crisis Three core regions of rainfall can be identified in Southern Africa - the Sahel, East Africa and South East Africa. The annual variability since the start of the ...
