--February is the last month of meteorological winter in the Northern Hemisphere, and of meteorological summer in the Southern Hemisphere. --By tracking the latest hours in white, the overhead sun can be seen to move E to W on a daily basis. --Thunderstorms travel W to E over the middle and higher latitudes in both hemispheres, and E to W in the tropics. --The equatorial trough/Intertropical Convergence Zone is usually well defined near the equator over the Atlantic Ocean during the month. --Almost no lightning occurs over the Sahara, except along the Mediterranean coast. --The Andes provide a sharp western boundary in a generally NNW-SSE line; no lightning occurs over the cold water offshore of the Andes. --Much of the lightning over Australia tends to be organized, mainly in the southeast and northwest. --In the southern portion of South America, clearing of lightning is apparent from S to N as cold fronts and attendant dry sinking air arrives to minimize lightning. ~Ron Holle

(Cont) --The major islands of SE Asia have thunderstorms most afternoons due to sea breezes and along the slopes of mountain ranges. --Several major storms move W to E from southern Japan. --A persistent area of lightning is SE of Hawaii near the equator in the North Atlantic during much of the month. --Long lines of thunderstorms move off the east coast of the U.S. several times through the month. --Activity in northern Europe is limited to scattered lightning in the North Sea and a storm over the UK on the 24th-25th. --The farthest south storms of the month occur SE of the southern tip of South America, on the 5th and 18th, and SE of Australia on the 23rd, close to Antarctica. ~Ron Holle
