赣南地区近58年来极端气候变化趋势分析
Trends of Extreme Climate in South Jiangxi from 1956 to 2013
摘要
Abstract
Extreme weather events have huge impact on human and the environment. In this article, Mann-Kendall test and linear trend method were adopted to examine the trend of eight indicators according to temperature and pre-cipitation data in south Jiangxi Province from 1956 to 2013. The indicators include average value of daily maximum temperature difference ( MxT) , average value of daily minimum temperature ( MnT) , average value of daily tem-perature difference (△T) , total precipitation ( P) , annual maximum 1-day rainfall ( AM1R) , annual maximum 3-day rainfall ( AM3R) , annual maximum 5-day rainfall ( AM5R) , and annual maximum 7-day rainfall ( AM7R) . Results showed that 1 ) there was no significant change in annual precipitation index, but the seasonal variations were obvious;2) temperature indicators showed the same trend both in year scale and in season scale, and in al-most all the sites MxT and MnT showed significant upward trend, in particular, MnT in autumn had the largest in-crease of 0.39 ℃ per decade. △T decreased except in spring;3) extreme precipitation events showed an upward trend, and AM1R and AM3R increased significantly, especially in winter. The research results suggest that the temperature trend in Southern Jiangxi is in accordance with global warming trend, and extreme precipitation events are intensifying.关键词
