Temporal Variability of Extreme Precipitation in Jiangxi during 1961-2018
نویسندگان
چکیده
Using 58 years (1961 to 2018) of daily rainfall data, this study focuses on determining trends in the annual and seasonal precipitation extremes Jiangxi, China, by choosing four extreme indices, including strong amount (SPA), mean intensity (MPI), days (SPD), frequency (SPF). The monotonic are tested using Mann-Kendall test for Sen’s method magnitude trends. effective sample size (ESS) was used eliminate influence serial correlation test. results indicated that station Zixi had strongest precipitation, while Wanzai weakest. each index showed an obvious regional feature over Jiangxi. Increasing indices were found at almost all stations, variability pronounced, especially frequency; majority these positive shown statistical tests. In spring, exhibited significant increasing Northeast Southwest Jiangxi; however, summer, only MPI a remarkable trend across For other few stations autumn, SPF most regions SPA SPD 6 3 respectively, which scattered northern middle parts. winter, with upward mainly located region, whereas patterns south region.

Assessment of Spatial and Temporal Variability of Extreme Precipitation Indices (North and West of Iran)
The frequency of precipitation extreme event can cause flood or change the drought period. Accurate understanding of these changes is necessary to take action to reduce these effects. In this research, temporal and spatial changes of 14 precipitation indices for eight synoptic stations in the North and West of the country were investigated. For this purpose, after reconstructing the daily preci...

seasonal and annual precipitation increased, except in the summer; the annual precipitation increased by about one millimeter pre year over the last 52 years. The spring precipitation significantly increased at the 99 % confidence level, while the mean summer precipitation insignificantly decreased at the 95 % confidence level. The extreme precipitation, including the maxima and minima, also ex...

[1] The observed trends in extreme precipitation events, and those in annual and seasonal mean precipitation in China during 1961–2001 are analyzed. The results show that the annual mean precipitation increases significantly in southwest, northwest, and east China, and decreases significantly in central, north and northeast China. The increasing trends in east China occurred mainly in summer, w...

Spatial and Temporal Variability of Annual Precipitation during 1958-2007 in Loess Plateau, China
The non-parametric Mann-Kendall method and Sliding t-test were applied in this study to analyze the spatial and temporal patterns of trends of the precipitation in the Loess Plateau from 1958 to 2007. The main trends of the precipitation in this region is downward, only four upward time series have not reach the significant level. Most of the abrupt changes happened in northeast of Loess Platea...
