--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 E to W on a daily basis. --Thunderstorms travel W to E over the middle and higher latitudes in both hemispheres, and more slowly from E to W in the tropics. ~Ron Holle

Southern Hemisphere --The Andes usually provide a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of the Andes. --New thunderstorms often form over southern Brazil, move NE, then NE and NW in a generally counter-clockwise pattern. --Areas of frequent daily formation of thunderstorm complexes are 1) east-central Brazil, and 2) NE Argentina to Paraguay and Uruguay. --Afternoon thunderstorms form daily and move W over sub-Saharan Africa, typically originating in Ethiopia and other higher-elevation regions to the S, and usually dissipate to the W before the next day. --Lightning is sparse over the Sahara south of the Mediterranean coast except for a few days over Algeria in the middle of the month.

Tropics --The major islands and land areas of Southeast Asia have thunderstorms on most afternoons due to sea breezes and along mountain slopes. --An intermittent equatorial trough, also called the Intertropical Convergence Zone, is in an east-west alignment over the western Atlantic and North Pacific.

--01 to 03 November: Tropical Cyclone Chapala is well defined by a circular lightning pattern as it approaches Yemen form the southeast. --01 to 04 November: Two major lines of thunderstorms sweep across most of Australia. --01 to 04 November: Most of India’s November lightning is over its southern tip. --08 to 13 November: Storms form in the lee of the Andes to the east along the Argentina-Chile border and move eastward. Several similar events occur later in the month. --11 to 22 November: Large complexes and lines of thunderstorms move eastward over the Indian Ocean from South Africa along a trough/frontal boundary; a similar pattern occurs on 22-23 November. --11 to 12 November: A significant severe weather outbreak begins in Kansas and expands NE. --12 November: The farthest south lightning of the month occurs southwest of the southern tip of Chile near Antarctica.

--16 to 17 November: A severe weather outbreak begins in the lee of the Rocky Mountains from Texas to Nebraska and moves east to southeast. --17 November: Australia has sea breeze thunderstorms over most of the northeast to northwest coasts. --18 to 23 November: Strong clearing occurs from south to north over Argentina northward to southern Brazil as a cold front brings in drier air. --18 to 20 November: Thunderstorms over Australia in very long lines move rapidly to the east-southeast. --26 to 29 November: An active lightning region is over Japan. --27 to 30 November: Strong storms occur over the eastern Mediterranean. ~Ron Holle
