Trends of climate parameters over Tanzania

Abstract

Analysis of the climate parameters over Tanzania were done for period 57-61 years. Rainfall and wind speed had greater variability than air temperatures. Positive significant trend of dry air temperature, maximal and minimal air temperatures were detected almost for all weather stations. As well positive trends of wind speed were detected just for stations Dodoma, Arusha, Mtwara and Mwanza. While rainfall trend analysis just for station Mtwara showed negative significant trend. In absolute values wind speed increased by 0.7-1.1 m/s, rainfall decreased by 89.3-136.1 mm, dry air temperature rise up 0.5-1.0 °C, maximal and minimal air temperatures values have grown by 2.0-3.6 °C.
