| 摘 要： | 根据倒春寒灾害性天气的标准，对1960～2004年的倒春寒过程进行了统计分析，描述了倒春寒过程的天气特征和造成的严重灾害，发现其中的最严重的倒春寒过程的特征，对倒春寒过程进行了分类，并且提出建立较为统一的倒春寒标准的建议。对云南冷空气过程进行了路径分析，发现云南冷空气路径有4条，它们是：西北路径、北方路径、东北路径和偏东路径，而倒春寒过程的冷空气路径主要是北方路径和东北路径，东北路径是云南省最多的一条冷空气路径，而北方路径却造成云南省最强的一次倒春寒过程。

| Abstract: | The processes of strong cold air in spring in Yunnan from 1960 to 2004 according to the standard of the processes has been statistical analysis, and the weather features of the processes causing serious damage of crops has been described. The processes of strong cold air in spring in Yunnan are classified, and a proposal of the united standard has been posed. The four route of the processes of strong cold air in Yunnan has been found: the northeast route, the northern route , the northwest route , the eastern route .The most route is northeast route, but the process in a northern route has caused the most serious damage in Yunnan. |
