人口死亡率与天气有一定的关系，以广州、上海两市１０个冬季和夏季的逐日死亡资料和气象资料，利用统计学和天气学方法得出，在最高温度达３４℃的“热日”，各类死亡数明显增多；而冬季死亡数随最低温度的下降而略有增加；广州夏季最大死亡率出现在“阴凉型”天气，而上海则是在“晴热型”天气，且上海死亡率受最高温度的影响大于广州；广州和上海冬季死亡率最大的天气均是“严寒型”，但广州死亡率受低温的影响要比上海大．在其他气象要素相似的情况下，风速对死亡率有一定的影响．
The mortality rate of the population has a certain relationship with the weather. Based on the daily death data and meteorological data of 10 winter and summer seasons in Guangzhou and Shanghai, the author uses the statistics and the synoptic method to find out that in the “hot day” with the maximum temperature of 34 ℃, , The number of deaths increased significantly; while the number of deaths in winter increased slightly with the decrease of the minimum temperature; the summer maximum death rate in Guangzhou appeared in “shady” weather, while that in Shanghai was in “sunny day” and the death in Shanghai The rate of maximum temperature was greater than that of Guangzhou. The highest winter and winter mortality in Guangzhou and Shanghai were all “cold type”, but Guangzhou’s mortality rate was more affected by low temperature than that of Shanghai. Wind speed has a certain impact on mortality in other meteorological elements.
