--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 east to west on a daily basis. --Thunderstorms travel west to east over the middle and higher latitudes in both hemispheres, and are stationary or move more slowly from varying directions in the tropics. ~Ron Holle

Northern Hemisphere --Alaska, Canada, China, Europe and Russia have small amounts of lightning. --A few large organized systems form over the central and eastern United States and move eastward. --In the vicinity of the Hawaiian Islands, an unusually persistent upper low and trough produce frequent lightning during February. --Intermittent lightning is near and over Japan through January. ~Ron Holle

Tropics --The equatorial trough over the Atlantic is well defined but in an unusual northeast-southwest alignment all month. The trough is diffuse over the Indian and western Pacific Oceans. --The major islands and land areas of tropical Southeast Asia have thunderstorms nearly every afternoon in sea breezes and along mountain slopes; they tend to move from the west earlier in the month, then from varying directions later in February. --Daily thunderstorms over Brazil move from the east-northeast but individual storms do not travel far or survive into the next day. --Lightning is nearly absent over the Indian subcontinent, Thailand, Laos, and Cambodia until late in the month. --The northern boundary of African thunderstorms moves to the north of the equator during February. ~Ron Holle

Southern Hemisphere --Lightning is frequent over Australia and New Guinea during the month, and is often in large organized systems. --Madagascar has thunderstorms every day in February. --The South Atlantic and South Pacific Oceans away from the continent are nearly lightning-free. --The Andes south of the equator provide a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of these mountains. --Lightning occurs at various times through February on the southern edge of the map at 55 degrees south latitude, including the southern tip of South America. ~Ron Holle
