--December is the first month of meteorological summer in the Southern Hemisphere, and of winter in the Northern Hemisphere. --The equatorial trough, also called the Intertropical Convergence Zone, is often well defined in an east-west alignment over the Atlantic Ocean between Africa and South America, and is more diffuse over the Arabian Sea. --Afternoon thunderstorms form daily and move W over sub-Saharan Africa, typically originating in Ethiopia and other higher-elevation regions to the S earlier in the month, then are stationary later in the month. --Madagascar has daily thunderstorms that grow in intensity through the month. --The northern edge of lightning activity shifted south after the 5th to south of 5 degrees north latitude, which places thunderstorms over the Atlantic south of the West African countries. --Lightning is almost non-existent over the Sahara south of the Mediterranean. ~Ron Holle
