--December is the first month of meteorological summer in the Southern Hemisphere, and of winter in the Northern Hemisphere. --Most thunderstorms in tropical regions move slowly from the east early in the month becoming from the west later in December, while at higher latitudes they move from west to east. --The major islands and land areas of Southeast Asia have thunderstorms on most afternoons due to sea breezes and along mountain slopes. --The equatorial trough, also called the Intertropical Convergence Zone, is well defined in an east-west alignment over the Pacific Ocean from Malaysia eastward, and somewhat apparent in the Indian Ocean. --Australia has active thunderstorms every December day in the form of sea breezes, cold fronts, and squall lines. --New Zealand has most of the month’s lightning from the 12th to the 19th. --Most of India’s December lightning is to the north early in the month. --China is nearly lightning free through the month. ~Ron Holle
