摘要
水陆交界地区出现的向岸风、离岸风局地环流使海岸附近排放的污染物限制在环流中较长时间,易造成大气高浓度污染状况。本文利用上海石化地面气象常规观测资料,确定了简单易用向岸风、离岸风划分方法,通过对气象数据库中1981～2005年24h逐时风资料分析,获得了向岸风、离岸风的各项长期特征。
The local air circulation, which is formed by the onshore-offshore wind in the regions where water and land meet, tends to retain the pollutants from the coastal area in the local circulation for a long time, causing highly polluted air conditions. This article presents a simple and easy-to-use method of onshore-offshore wind division by using the meteorological routine ground observation data, and acquires many long-term characteristics of the onshore-offshore winds through an analysis of the hourly wind data in the meteorological database from 1981 to 2005.
