Abstract:

This paper describes temporal variation of annual precipitation trend from 1771 to 1991 at Seoul, Korea. Analysis of the series shows no distinct trend over years. A linear trend would be drawn though, it is insignificant statistically. The reason for that the series does not show any distinct trend could be its large interannual variations. The series has an extremely dry spell lasted for twenty-six year period from 1884 to 1910. Estimates shows that, during this dry period, 58.4 percent of streamflow reduction occurred owing to 29.3 percent of precipitation decrease compared to the rest of the series.
