摘要
统计1959～2008年抚顺市冰雹天气,分析冰雹气候规律和天气形势环流特征,总结冰雹对农业影响。结果表明:抚顺地区50年冰雹年变化趋势明显减少。冰雹出现在每年的4～11月,5、6月出现频率最高。冰雹地理分布特点西部地区最多,北部地区次之,南部地区最少。冰雹出现次数与平均气温有较好的对应关系,低温年与多雹年对应年份较多,高温年与少雹年对应年份较多。冰雹天气500hPa环流分为冷涡及冷涡后部型、高空槽型和槽后西北气流型。冰雹出现对农业带来严重危害,应采取必要措施,减少冰雹灾害造成的损失。
Based on hail weather data in Fushun from 1959 to 2008,the law of hail climate and synoptic situation circulation characteristics were analyzed,and then the impacts on agriculture were summarized.It shows that the annual variation trend of 50-year hail is evidently decreasing in Fushun region.The hail appears in 4-11 month annually.The most frequency appears in May and June.The specialty of the hail geographical distribution is its most appearance frequency in Westward and the second in Northleast and the least in South.The 500hPa circulation patterns of hail weather include cold vortex,cold vortex rearward type,upper trough type,northwest airflow type behind trough.Hail brings seriously hazard to agriculture.Therefore,some necessary measurements should be adopted,reducing the loss of hail damage.
