摘要
利用Weatherhawk全自动气象站对上海浦东新区沿海水杉防护林系统内外风况的时空动态进行为期3a的定位观测研究。结果表明:(1)风况分布特征与亚热带季风湿润性气候特点基本相符;(2)水杉防护林系统对风速有明显的削弱作用;(3)风速的日变化呈单峰曲线,最低值一般出现在日出时分,而峰值一般出现在正午时分;(4)随着季风环流对风向与风速的影响,防护林的防风效应也发生了一定的变化。
The temporal and spatial characteristics of wind regime have been monitored using the Weather- hawk automatic weather station for 3 years in the Shanghai Pudong coastal area. The results were as fol- lows. （1） Characteristic of the wind regime,in this study area,was in accordance with the climate of humid subtropical monsoon. （2） The wind speed was obviously reduced through the Metasequoia glyptostrobo- ides shelter forest. （3） The diurnal change of wind speed displayed a curve of single peak,with the mini- mum value at sunrise and peak value at midday. （4） The sheltering effect was changing with the circulation of monsoon.
