Abstract:
Using daily precipitation and air temperature data of Lhasa to analyze the nightrain rate in rainy season (May-September) during years 1955-2007, the results could be summarized as follows: The variations of nightrain rate was comparatively stable in whole rainy season, without obvious interdecadal changes during the past 50 years. The nightrain rate was significantly associated with daily precipitation, and the nightrain rate increased with the enhancement of precipitation when rainfall was below 25 mm, it was the minimum 75.2% when daily rainfall was below 1 mm, and it was the maximum 93.4% when daily rainfall was 25 mm. There is a significantly negative correlation between night rain rate and daily temperature. In the meantime, the nightrain is related with the terrain. The high nightrain rate has its advantageous aspect, but also it will bring some negative influences.
