| Abstract | Southeast Asia is a region which is highly susceptible to climate change during recent decades. Although many researches have been conducted in this region the Upper Ayeyarwady Region of Myanmar is still yet less focused in this regard. This research study focuses on historical patterns of temperature and precipitation of Upper Ayeyarwady River. Trends in temperature and precipitation are analyzed in daily, monthly, seasonal and annual scales. Six temperature and five precipitation related indices are analyzed in this study. Data sets cov- ering from 1975-2014 are used in this study. Non-parametric MK test and Sen's Slope are utilized in-order to examine the level of significance and the slopes in trends. Rainfall of Myanmar is dominated by mainly three monsoons. MK test and Sen's Slope techniques interpret that Mandalay, Myitkina and Putao showed strong increasing precipita- tion trends of 4.778, 13.561 and 15.237 mm per 40 years during Southwest monsoon. It is a significant fact that Southwest monsoons only show increasing trends in precipitation among the three seasons. Decreasing patterns in R5, RIO, CWD and increasing trends in CDD were observed in the period of 1995-2014. In general warming is observed in the basin but de- creasing trends of temperature is observed during the monsoon seasons in the upper part. The highest increase in annual precipitation was in Putao which showed an increase of 0.380 mm per year. Myitkina recorded the highest number of consecutive dry days amounted to 153 days in 1979. Myitkina was the only station to exhibit increasing trends during 1975-1994 and 1995-2014 in TNn and TNx .. |
