With a population of approximately 1.2 billion, Africa only has 37 weather radar stations, in stark contrast to the 636 stations in the United States and European Union. This scarcity of weather stations and early warning systems leads to inadequate disaster preparedness and response, compounded by maintenance issues with many existing radar ...

A one-month lag such as this should be represented by roughly a 1500 to 2000 year lag in the monsoonal circulation maximum, because a July insolation maximum in a 19,000 to 23,000-year precession cycle occurs ...
