| 摘 要： | 目的]研究玉溪市低温冷害成因和天气环流特征。方法]分析了玉溪市发生低温冷害的成因,介绍玉溪市低温冷害类型及其对农作物的影响,并分析总结了冷空气影响路径和发生低温冷害天气的典型环流特征。结果]玉溪市低温冷害是由于其地形地势的影响和气候成因造成的,低温冷害包括霜冻、春季低温、秋季低温3种类型;玉溪市冷空气的影响路径有东北、北方、西北和偏东4条路径。降雪天气的环流特征主要是南支槽、强冷空气型和冷锋切变型;高空冷平流与低层冷高压控制下长时间夜间晴空辐射、冷却、降温是重霜冻形成的主要环流特征;8月低温的环流背景就是有利于较强冷空气在盛夏入侵玉溪市的高空环流,影响玉溪市的环流主要为北冷槽南低压型。结论]该研究为天气预报和相关专业科技人员提供参考。
