World_6HR_Nov_2014

--November is the last month of meteorological autumn in the Northern Hemisphere, and of meteorological spring in the Southern Hemisphere. --Note that 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, also called the Intertropical Convergence Zone, is intermittently active in the North Atlantic and Eastern Pacific Oceans through the month. --Well-organized areas of thunderstorms move eastward from the E coasts of large land masses in the middle latitudes of North and South America, Africa, and Australia. --Almost no lightning occurs over the Sahara, except along the Mediterranean coast. --The Caribbean Sea is usually a lightning minimum due to strong easterly winds and subsidence from land areas on all sides. ~Ron Holle

--14 to 16 and 20 to 24 November: Large thunderstorms form over central Saudi Arabia and move NE. --17 to 18 November: A well-organized storm moves SW from southern Guyana. --20 to 24 and 28 to 30 November: Frequent lightning over Morocco and adjacent areas. --27 to 28 November: Chaotic directions of movement are apparent over the Amazon. Although a tendency for movement from the ENE is present, some storms move from the S. ~Ron Holle
