This area is an arid to semi-arid zone with low rainfall, intense heat and degraded soil conditions. The dry zone is one of the most vulnerable areas to climate change impacts as compared to other parts of the country affecting ecosystem services and communities living in this region. The main objective of this study was to improve our understanding of the long term variations and extreme changes in temperature and precipitation in this dry zone region. Such information is necessary for quantifying the impacts of climate change. Temperature and precipitation data over 41-year period (1975-2015) from five selected meteorological stations (Mandalay, Monywa, Meikthila, Minbu, Pyinmana) as proxies for changes in this region were analyzed. The results indicated the increase in maximum temperature by 0.25oC~0.35oC/decade and minimum temperature by 0.04oC~0.27oC/decade. Between 1975 and 2015, most of the temperature extremes showed significant warming trends. Trends in annual total pre c i p i t a t i o n and number o f heavy precipitation days indicate a slight increase with 2~28 mm/decade and 0.25~0.97 mm/ decade, respectively. Therefore, it is evident that significant changes in climate patterns and extreme climate parameters have occurred in this area.
