Synoptic-Scale Weather Disturbances that Influence the Fire Climate in Southeast Asia During the Normally Dry Period
Abstract
Fire climate in Southeast Asia is affected by two major factors, rainfall and cloud cover. By 'fire climate' one means the climate that affects the inception and behavior of wildfire. In our study of the fire climate in Southeast Asia we investigated, when, for how long and by what mechanism the normally dry period (November through April) is interrupted by widespread rain and clouds. The author found five types of synoptic-scale weather disturbances usually responsible for extensive rainfall over Southeast Asia during the dry period. Case histories are given of general rain that were caused by these five types of disturbances: (1) 30 November 1962--tropical cyclones and easterly waves; (2) 21-23 March 1963--troughs in the westerlies; (3) 24 and 25 November 1962--superposition of trough in the westerlies on easterly waves; (4) 29 March 1963--surges of the northeast monsoon; and (5) 7-9 March 1963--tropical troughs.
