Tropical Storm Effect with Respect to Weather Over the Indonesian Region

H. K. Bayong Tjasyono

Tropical storms emerge in the oceans with surface temperature greater than 26⁰C and the emergence of tropical storm is related to thermal ridge. This paper presents two tropical storms in the southern hemisphere i. e.: tropical storm ERROL emerged on January 13, 1982, then dissipated on January 20, 1982, and tropical storm BRUNO emerged on January 15, 1982 and it decreased in intensity, then dissipated on January 20, 1982. Climatological data have shown that some rainfall stations in Indonesia, south of the equator, which are located near the tropical storm track, showed an increase in rainfall ranging from 123% to 355% of its normal rainfall values. In some stations, wind speeds also increase beyond 20 knots during the tropical storm periods.
