The typical results were as follows: (1) The average of annual rainfall was 1203 mm at average, 1726 mm at maximum, and 666 mm at minimum. (2) The decreasing rate of the annual rainfall was 5.37 mm/year. (3) Trend of rainfall intensity in each rainfall duration showed an increase of which rate were 0.005~0.256 mm/h/year, contrary to the annual trend.
