| Abstract: | With routine meteorological data from 1951 to 2009 at Jinzhou city,the variation characteristics of the temperature,precipitation,sunlight,wind speed and evaporation were analyzed.The results showed that the annual average temperature increased significantly and sunshine decreased in the last 59 years at Jinzhou city.Annual precipitation and the average speed were significantly decreased.Evaporation augmented and the average evaporation was 2.1 times than the average Precipitation.The sunshine time was positively correlated with evaporation and was negatively correlated with annual precipitation. |
