The temperature, rainfall and sunshine were analyzed based on the meteorological data in Chaoyang City in 2014. The results showed that annual average temperature was higher in Chaoyang City in 2014, and air tempera- ture varied over a much wider range. Phased low temperature in spring was obvious. The space-time distribution of less raifall was uneven and the summer drought was serious. The annual sun- shine hours were less in 2014. Summer drought, local rainstorm, mountain tor- rent, hailstone and other meteorological disasters brought greater loss for agricul- tural production and people＇s life and property.
