安徽省灵璧县一次灾害性雷雨大风气象服务案例分析
|
摘要
从宿州市灵璧县2015年8月5日雷雨大风发生前的环流背景、能量条件和灾情发生当天的环流形势特征及临近时雷达图特征等方面,探讨此次灾害过程的成因机理及特征,且逐级再次梳理省、市、县气象预报预警服务过程,总结服务工作得失。结果表明,此次雷雨大风是受副热带高压边缘暖湿气流和高空低槽东移扩散的冷空气共同影响;副热带高压北抬加强,持续高温积累的不稳定能量有利于强对流天气的发生、发展。在此次强对流天气来袭临近前,气象部门针对此次雷雨大风天气过程及时发布了准确的预警预报信息,在此次过程中气象部门密切关注天气形势,省、市、县三级气象部门联合响应,在防灾减灾工作中发挥了较好的效果和作用。
The causes mechanism and characteristics of a thunderstorm gale on Aug. 5th,2015 in Lingbi County Suzhou City were discussed from aspects of circulation background,energy conditions,circulation features and radar chart characteristics. Provincial,city and county meteorological forecast and early warning service process was reviewed,the gains and losses were summarized. The results showed that the thunderstorm gale was affected by subtropical high edge warm air and cold air of high altitude low trough eastward diffusion; the accumulation of unstable energy was conducive to the occurrence and development of strong convection weather. Meteorological departments timely released accurate warning information and played a good role in disaster prevention and reduction.
