World_24hr_Nov_2018

--November is the last month of meteorological autumn in the Northern Hemisphere, and of spring 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 move more slowly from varying directions in the tropics. Northern Hemisphere --Alaska, Canada, China, Europe, and Russia have minimal lightning. --The Mediterranean Sea, and adjacent shores of Europe and Africa, have several large cyclonic circulations that move west to east. --Over the Indian subcontinent, lightning is mostly in the south and ends by mid-month. --Lightning activity over the U.S., Gulf of Mexico, Cuba, Mexico, and Central America is much weaker than during October. ~ Ron Holle

Tropics --The equatorial trough, also called the Intertropical Convergence Zone, is well defined over the Atlantic, more sporadic over the Eastern North Pacific, and absent in 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 slowly E to W early in November and later from W to E. --Over all of Brazil but the eastern tip, daily thunderstorms form, then move from the east or northeast. Individual storms do not travel far or survive into the next day. Southern Hemisphere --The Andes provide a sharp western boundary in a NNW-SSE line, and no lightning occurs over the cold water offshore of the Andes. --Over Australia, most lightning is in large organized systems moving from the west or southwest. --Organized thunderstorms form often over northern Argentina and Uruguay, and move NE. ~ Ron Holle
