General --February is the last month of meteorological winter in the Northern Hemisphere, and of summer in the Southern Hemisphere. --By tracking the latest hours in white, the overhead sun can be seen moving E to W on a daily basis. --Thunderstorms travel W to E over the middle and higher latitudes in both hemispheres, and move more slowly from varying directions in the tropics. Northern Hemisphere --Alaska, Canada, China, Europe, and Russia have almost no lightning in February. --The Mediterranean Sea has stationary and moving thunderstorm systems through the month. --Over the Indian subcontinent, lightning is over the northern portion and moves from W to E. --Lightning activity in February over the U.S., Cuba, Mexico, and Central America is primarily over the U.S. Gulf Coast and adjacent regions to the north. ~Ron Holle

Tropics --The equatorial trough, also called the Intertropical Convergence Zone, is well defined over the Atlantic, sporadic over the Eastern North Pacific, and diffuse over the Indian Ocean. --The major islands and land areas of tropical Southeast Asia have daily thunderstorms in sea breezes and along mountain slopes; they move from varying directions through the month. --There is minimal lightning activity over the Philippines, Thailand, Myanmar, Vietnam, and Cambodia. --Storms form daily over East Africa, and move to the west or southwest. --Thunderstorm activity is present every day over Madagascar, while the Sahara is nearly devoid of lightning. --There is much more lightning over the northeast region of Brazil than during other months. ~Ron Holle
