摘要
干雷暴是一种在防火期内极易造成森林火灾的天气过程,国外已将其作为火险天气预报的重要组成部分进行了数十年研究,但在国内可供借鉴和参考的相关内容并不多。文中从干雷暴的特征和形成条件、预测及应用等方面梳理了国内外研究脉络,并对存在的问题和未来研究趋势进行了探讨和展望。基于我国林区探空监测站不足的特点,建议使用地面气象资料模拟输出探空数据,并借鉴国外闪电活跃等级、RF99等干雷暴预测研究成果,结合加拿大火险天气指数,在我国干雷暴引发雷击火较多的大兴安岭地区进行探索性应用,以减少这种灾害性天气对生态环境的危害。
Dry thunderstorm is a weather process that easily causes forest fires during the fire danger season,and it has been studied abroad for decades as an important part of the fire weather forecast.However,there is little study that can be learned and referred in China.This paper reviewed literature about the characteristics,formation conditions,forecasting methods and applications of dry thunderstorms at home and abroad,analyzed and discussed the existing problems and future study on the field.In light of the problem that upper-air meteorological stations is short of,it was then proposed to simulate and output upper-air meteorological data with above-ground meteorological data,and carry out experimental application of the fire weather index developed by Canada by referring to the study results of lightening active level and RF99 in Daxing＇an Mountains where dry thunderstorms often induce forest fires.The study is aimed at reducing the damage on forest eco-environment by such disastrous weather.
