摘要
本文通过对昆明地区30年的6~9月地面十四点气压场,温度场和湿度场的观测资料进行逐日功率谱分析,得出昆明地区上述要素场存在5~7d的周期振荡,从而为中短期天气预报提供客观依据.
It states there is a oscillatory periodicty as long as 5~ 7 days for the weather element fields in Kunming region to be given out by using power spectral analysis method. Some advices are given out on the weather forcast.
