摘要
利用辽东湾温坨子地区大气扩散试验资料,采用风场诊断模式,对拟建核电站厂区冬季水平风场的分布特征进行了研究。结果表明:冬季该地区水平风场分布主要有3种形式:(1)呈偏南风型的风场;(2)偏北风型的风场;(3)厂址附近位于高低压中心之间,或整个区域是一均压场,这时系统风弱,局地风(包括山谷风及海陆风)明显,整个区域地面风场比较混乱。夏季该地区水平风场分布主要有4种形式:(1)受季风控制,呈偏南风型的风场;(2)系统风较弱,呈海陆风型的风场;(3)锋前低压控制,产生切变型的风场;(4)受季风控制呈偏北风型的风场。
Using the wind field diagnostic model and atmospheric diffusion experimental data in winter and summer in Wentouzi area of Liaodong Bay, the distribution characteristic of horizontal wind field at nuclear power station have been analyzed. The result show that there are mainly three patterns for distribution of horizontal wind fields at this area in winter, they are: (1) southerly wind pattern, (2) northerly wind one and (3) the local wind one, the nuclear power station is between high and low pressures, or in a homogeneous pressure field, the mountainvalley wind flowed obviously, this kind of surface wind field of this aera is favourable to the confusion. There are mainly four patterns for distribution of horizontal wind field at this area in summer, they are: (1) sountherly wind patten, (2) sealand wind one, (3) shear wind one and (4) northerly wind one.
