| One of the approaches usedtoinvestigate trend step changes in precipitation isstatistical techniques.The main objective ofthis paper is toidentify and analyze thetrend ofchanges in annual and seasonalprecipitation overthe studied area.The current study employs monthly precipitation data from 1951 to 2010 derived from a weather station in Kermanshah. Using non-parametric Mann-Kendall test and graphic based methods depicting total annual and seasonal (cold and warm seasons) precipitation, the research analyzes trend changes of Kermanshah over different time series. Primarily, data changes in studied seasons and years are analyzed. Then, type and time of these changes are identifed. Averages of monthly precipitation overKermanshah during warm and cold seasons are determined as 47.9±33.64 Mm and 169.68±54.56 Mm, respectively. There is no signifcant trend in annual precipitation over Kermanshah. Analysis of averages precipitation of warm and cold seasons indicates no signifcant trend; however, warm season seems to follow a decreasing trend in general. Yet, there are leaps in the average levels of both annual and seasonal precipitation. The obtained results show that general trend of change in average precipitation during warm seasons is downward with leaps of average during the studied period. But, in general, there is no signifcant trend of change in the averages of annual and seasonal precipitation during the studied time. |
