由于海陆垫面受热不同产生水平气压梯度,白天空气从海洋流向陆地,夜间相反。在海陆界面附近形成昼夜不同的中小尺度的海陆风环流。它的影响高度、范围,持续时间……等对沿岸地区大气的影响,尤其对沿岸地区环境污染的作用,越来越引起人们的关注。 Due to the heating of the land surface, the surface pressure gradient is generated by the heat, and the air flows from the ocean to the land during the daytime, and at night is opposite. Around the sea and land interface formation of day and night different sea and land breeze circulation. Its influence height, range, duration ... etc. Have aroused people’s concern more and more on the atmospheric environment in coastal areas, especially on the environmental pollution in coastal areas.
