Trend Analysis for Some Climate Variables of Selected Stations in Iraq


Abstract:This search deal with the effect of worldwide global warming on surface air temperature, relativityhumidity and rainfall for selected stations in Iraq. Monthly surface air temperature, relativity humidity andrainfall were analysed to get temporal trends variation with the period (1984-1999) by using Mann-Kendalltest to detect the significant trend. The test showed that surface air temperature and relativity humidity hada positive trend at all station with a highest value in Basrah station (0.085) and (0.344) respectively, whilethe test for rainfall showed a negative trend at all stations with a highest decreasing value (-1.606) in Basrahstation too.
