1) Seasonal cycle of the West african monsoon:

Mean seasonal cycle (1950-1999) of mean sea level pressure (shading at the surface) mean 925hPa winds (vectors in white). Tropical easterly jet (U wind at 200hPa, gray contours) African Easterly jet (U wind at 600 hPa, white contours), the vertical section is the temperature.....

You can note the establisment of the monsoon flow during boreal summer, the northward migration of the thermal low following the sun run (see the vertical profile), and the northward migration of the jets, and their westward extension.....




2) Seasonal cycle of the Inter tropical convergence zone (ITCZ), overlayed onto the orography

You can note the influence of the mountains upon rainfall (Cameroon mounts, Fouta djalon, Ethiopian highs). The impact of the Himalaya during the establishment of the Indian monsoon can be noted too......
