Jun 4, 2019 · About 80–90% of the total rainfall amount in the Sahel comes from storms that are especially well organized—they are larger than 80–100,000 km 2 and live longer than 6 hr—in spite of those storms being just 11% of the total MCS population (Mathon et al., 2002). Seasonal rainfall variability, thus, likely depends on the controls upon the ...

The Red Sea surrounds the Sahara on the east, the Atlantic Ocean on the west, on the north the Mediterranean Sea and the Sahel, a semi-arid tropical savannah of Sudan and the Valleyof River Niger of Sub Saharan Africa on the south. This gigantic desert is spread out in 11 countries: Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Wes...
Sahara desert is the World’s hottest large land area. Two climatic regimes dominate the Sahara desert: a dry northern subtropical climate and a dry southern tropical climate. The characteristics of dry subtropical climate are unusually high-temperature ranges, annual and diurnal, hot summers and cold to cool winters, and two precipitationmaximums. ...
The Sahara desert has grown about 10% in size since 1920, according to a 2018 study published in the Journal of Climate. Usually, all deserts increase in the area during the dry season and decrease during the wet season, similar to what happened in Sahara. However, human-caused climate change intervenes with natural climate cycles and causes the Sa...
May 25, 2017 · Here we show that Sahel rainfall is skilfully predicted on inter-annual and multi-year (that is, >5 years) timescales and use these predictions to better understand the driving mechanisms.

Sep 15, 2022 · We focus on July–September average rainfall in the central Sahel region (0–30°E, 10–20°N), which is more susceptible to changes in remote moisture import than the coastal regions further to the West.

Total rainfall during the 1996 wet season averaged between 200 and 1000 mm across the region ( Fig. 52a ), with the largest amounts in the southwestern Sahel and western Guinea and the smallest amounts in the North.
It’s also one of the most vulnerable to climate change and variability. Since the mid-1980s, average rainfall in the Sahel has partially recovered, possibly contributing in places to a ‘re-greening’ of vegetation so widespread that it can be observed from space.
