摘要
利用1961—2010年伊吾县地面气象观测资料,统计分析了气温、相对湿度、日照、风速、降水量、大风日数的变化特征及其时空分布情况。伊吾县极端最低气温为-31.9℃,出现-30.0℃以下的年份仅有3年,冬季冷空气活动较少,≥10℃积温2 492.4℃,平均气温10℃以上的天数一般在160 d左右;4—9月月平均日照时数均在280.0 h以上,光照非常充足;平均风速3.5 m/s,平均相对湿度50%,具备发展特色林果业的气象条件。
Based on the surface meteorological observation data in Yiwu County from 1961 to 2010, the changing characteristics and temporal and spatial distribution of air temperature, relative humidity, sunshine hours, wind speed,precipitation and gale days were analyzed. The extreme minimum temperature was-31.9℃ in Yiwu County, and only three years were lower than-30℃.The activity of cold air was unfrequent in winter. ≥10℃ accumulated temperature was 2 492.4℃. The days of average temperature above 10℃ was 160 days. The sunshine was enough, and mean monthly sunshine hour was above 280.0 hours from April to September. The average wind speed was 3.5 m/s, and the average relative humidity was 50%. These meteorological conditions were suitable to develop distinctive forestry and fruit industry in Yiwu County.
