A compilation of climatological data for Southeast Asia that shows the monsoonal influences on wind, rain, and cloudiness in a synoptic pattern of the region. The compilation provides a base for understanding the weather in Southeast Asia and for developing empirical forecasting rules. Many similarities to weather observed in the United States are noted, since, as in the United States, large areas of Southeast Asia are affected by polar continental and tropical maritime air masses. Maps show general circulation and daily cloud conditions for winter and summer, and precipitation for all four seasons. Taken together, they relate the major broad-scale variations of these parameters throughout tropical Southeast Asia seasonally and give a cursory understanding of the forecasting problems.
