Characteristics of Precipitation in Nong Saeng Village, Khon Kaen Province, Northeast Thailand

Abstract

From the results of observations in Nong Saeng Village, Khon Kaen Province, Northeast Thailand from May 2002 to February 2005, precipitation was concentrated from evening to early morning in the middle of the rainy season. However, at the end of the rainy season, the concentration of precipitation during these hours decreased and the precipitation ratio in the morning increased. Extraordinary precipitation in the dry season had the same tendency as at the end of the rainy season. The frequency of gusty rain against all rain was lower than the frequency of the previous and following month during the middle of the rainy season. These results are a reference for development of water control systems and erosion control with cropping systems that are adjusted for precipitation patterns.
