中文摘要: 利用中尺度地面观测资料,以广东省阳江—电白之间沿岸近似东西向的海岸线为例分析了东西向海岸线对局地性降水的作用。结果发现:夏季,在梯度风较弱的背景下,这一带沿海的海陆风环流非常显著,在海陆风环流更替的后半夜—早晨和午后—傍晚期间,海风锋随着更替的局地性环流移经上述两地区沿岸,在其它条件的配合下可造成局地性降水天气。

Abstract:Based on the meso-scale surface observations, the effect of zonal coastline, as an example, from Yangjiang to Dianbai, on local precipitation is analyzed. The results show that in summer, sea and land breeze circulation appears obviously under weak gradient wind condition. In the early morning, and from the afternoon to evening, the sea breeze front moves along the coast with the replacement of the sea and land breeze circulation, local precipitation could appear under certain conditions.
