| Abstract: | The characteristics of the sunlight,temperature,precipitation and wind speed were analyzed with conventional meteorological data from 1957 to 2004 in Panjin wetland.The results showed that the variety of monthly sunlight appeared a double peaks curve.The peak values of sunshine occurred in May and in September,respectively,while the lower value was in July.The annual average temperature in Panjin wetland in the latest 48 years increased obviously,especially in winter,followed in spring.But the increase trend became slight in summer.The annual average extreme lowest temperature increased obviously,too.However,the annual average wind speed showed significant decrease trend in the latest 48 years.The trend of the monthly average wind speed appeared a double peaks curve. |
