【摘要】 基于风廓线雷达（简称WPR）水平风资料并结合地面资料,采用局地环流分离与判定方法,对蓬莱海陆风进行计算识别。结果表明:WPR能清晰完整地捕捉到海陆风的时空演变与结构特征,据此构建了海陆风时空结构模型;WPR资料识别出蓬莱2014年84天海陆风日,时空变化特征显著,海风生消盛行时间分别为10—12时、17—18时,且随高度增加滞后1～2 h;陆风顶高（最大1180 m、平均674 m）较海风顶高（最大940 m、平均450 m）大且两者有较好的相关性;海风强度总体大于陆风,二者最大风速分别为6.7、5.1 m·s^-1。识别出4—9月共15天海风环流,昼间海风顶高（513 m）较陆风的（951 m）低,海风最大强度(6.0 m·s^-1)较陆风的(3.9 m·s^-1)大,海风与陆风风向的反相夹角在83.7°～174.9°,均值125.6°。海风和陆风其各自风层内风向均呈现随高度、时间向顺时针方向偏转趋势,风速一般是先增大后减小。更多还原

【Abstract】 Based on the wind profile radar（WPR） horizontal wind data combined with the ground data, the local circulation separation and determination method is used to calculate and identify the Penglai sea-land breeze. The results show that WPR could capture the spatial and temporal evolution and structural characteristics of sea-land breeze in a clear and complete way, so a sea-land breeze spatio-temporal structure model is constructed on this basis. Out of the WPR data, Penglai’s 84 sea-land breeze days in 2014 are identified with significant spatio-temporal variations. The times of sea breeze generation and extinction appear from 10 to 12 o’clock and 17 to 18 o’clock respectively, delayed by 1—2 h with the increase of height. The top height of land breeze（maximum 1180 m, averaged 674 m） is higher than the top height of sea breeze（maximum 940 m, averaged 450 m） and they show a good correlation to each other. The sea breeze strength is generally stronger than the land breeze, with peak wind speed of 6.7 m·s^-1and 5.1 m·s^-1, respectively. There are a total of 15 sea-breeze circulation days identified from April to September. During the daytime, the top height of sea breeze（513 m） is lower than the land breeze（951 m）. The maximum sea breeze strength(6.0 m·s^-1) is larger than the land breeze(3.9 m·s^-1) with the inverted angle between the directions of the two ranging from 83.7° and 174.9°, and an average of 125.6°. The wind directions in each wind layer of sea breeze and land wind show a tendency to deflect in a clockwise direction along with the changes of height and time, and generally the wind speed increases first and then decreases.更多还原
