1965—2016年乌审旗冰雹时空分布特征
|
摘要
利用乌审旗3个站的1965—2016年逐时、逐日冰雹资料,分析乌审旗近52a来冰雹发生的空间分布、年际变化、月际变化和持续时间等特征。结果表明,乌审旗近52a平均降雹日数总体呈减少趋势,平均每10a减少0.8d;1965-1990年冰雹较多;2000—2015年相对较少;3—10月为降雹月,主要集中在6—9月,其中8月最多;一日发生降雹的时间主要集中在14—18时,以15—16、17—18时最多;降雹持续时间以5min以内居多;空间分布为北部降雹日数多于中部及南部。
The spatial distribution, interannual variation, monthly variation, and duration of hail occurrence were analyzed in Uxin Banner utilizing the hourly and daily hail data from the three stations of Uxin Banner from 1965 to 2016 during the past 52 years. The results showed that the average number of days of haggling in Uxin Banner was generally decreasing during the last 52 years, with an average of 0.8 days per 10 years; hail was higher in 1965-1990; relatively less in 2000-2015; and in March and October, it was mainly in From June to September, the most in August; The time of day falling occurs mainly at 14-18 hours, with a maximum of 15-16 and 17-18 hours;the duration of hail falls within 5 min; the spatial distribution is that the hail days in the north are more than those in the middle and south.
