提要：利用各种气象观测资料，研究了2010年1月28日和1月30日发生在粤东地区的两次海陆风生消的演变特征和环流背景，并通过数值模拟揭示了海陆风环流的结构特征。主要结论有：（1）两次海陆风出现时。粤东分别位于冷高压底部和入海高压后部，境内为均压场，后期随着冷高压南压或低压倒槽东移，粤东转受偏北风或偏南风控制．海陆风特点消失；（2）陆1风环流盛行时高空存在返回气流，没有贴地逆温，但在风向切变区域有逆温出现，海风环流高空无明显返回气流，无逆温出现；（3）高分辨率的模拟结果揭示，处于高压后部的海风环流在持续时间、垂直厚度和水平范围上都比高压底部的海风环流强。

Using available meteorological observation data, the evolution characteristics and circulation background of two sea-land breezes cases over eastern Guangdong province in Jan. 28 and Jan. 30 in 2010 were studied. The structure characteristics of sea-land breezes circulation were also discussed through numerical simulation. The major conclusions include: 1 ) When two land-sea breezes appears, There is equalizing-pressure field within Guangdong. Eastern Guangdong are located respectively at the bottom of the cold high and the rear of the into-sea high pressure. With the cold high pressure east, Eastern Guangdong was controlled by northerly or moving south or inverted trough of low pressure moving southerly winds, sea breeze disappearing.2)When land breeze circulation is prevailing, there is a return airflow (no temperature inversion) in high altitude (near surface ).There exists temperature inversion in wind shear region. There is no return airflow and no temperature inversion in high altitude of sea breeze circulation area. 3) Through the high - resolution simulation test, the duration, the vertical thickness and the horizontal extent of the sea breeze circulation in high-pressure rear are stronger than those of the sea breeze circulation at the bottom of high-pressure.
