茂名地区极端降水时空分布特征分析
Temporal and Spatial Distributions of Extreme Precipitation in Maoming Area
摘要
Abstract
Based on the daily rainfall data of 45 meteorological stations in Maoming area, this paper analyzed the temporal and spatial distribution characteristics of the extreme precipitation events in Maoming. The analysis showed that the threshold and intensity of extreme precipitation decreased from south to north, the average annual total precipitation decreased from west to east, and the frequency of extreme precipitation decreased from northwest to southeast. The occurrence of extreme precipitation events peaked in June and the total precipitation peaked in August. The total precipitation, frequency,and intensity of extreme precipitation in Maoming area tended to increase, and the inter-annual variation was distinct. The characteristics of sudden change of extreme precipitation index were not obvious. The annual total precipitation and frequency exist quasi-3a short cycle, 12a long cycle.关键词
