摘要: 利用EOF、REOF、M-K突变检验等方法,分析了台湾地区1961-2008年降水量的变化情况,结果表明:台湾本岛年降水量丰沛,澎湖列岛的年降水较少。台湾岛年降水的空间分布既有一致性,也存在东-西部、南-北部的差异。台湾岛的年降水可分为3个气候区,即北部、中西部和东南部。除台湾岛东南部外,整个台湾地区的年降水量均有增加趋势和突变现象。

关键词: 台湾地区, 降水, EOF, REOF, 突变分析

Abstract: Changes of precipitation in the Taiwan area in 1961-2008 was analyzed by using EOF, REOF, M-K abrupt change analysis. The results show that the annual precipitation was great in the Taiwan Island, but far smaller in the Pescadores. The spatial distribution of annual precipitation in the Taiwan Island not only had the coherence in the whole area, but also showed variations from east to west and from south to north. The annual rainfall field in the Taiwan Island can be divided into north, mid-west and southeast sub-regions. The annual precipitation displayed an increasing trend and abrupt changes in the island except the southeast sub-region.

Key words: Taiwan area, precipitation, EOF, REOF, trend analysis, abrupt change analysis
