SHANGHAI URBAN INFLUENCE ON FOG
-
摘要: 上海是我国最大的工商业城市,城市气候效应十分显著1。本文应用上海气象台(位于市区龙华)气象资料1)和上海十个郊县气象资料2),来分析上海城市对雾的影响。Abstract: By comparing the simultaneous meteorological records in Shanghai urban area with those in its suburbs, we find the urban influence on fog is very remarkable. There are some favorable conditions for the formation of fog (such as weaker wind velocity and more heavy pollution products actingas atmospheric condensation nuclei) and some are unfavorable (such as heat island effect tended to diminish temperature inversion and relative humidity).
