摘要
利用GAME-Tibet1998年加强观测期安多探空观测资料与CAMP-Tibet2004年加强观测期那曲探空资料,分析了藏北高原夏季大气边界层加热(冷却)特征.结果表明:夏季,藏北高原大气边界层的大气加热(冷却)率的逐日变化特征明显,晴天时较大,多云和降雨时较小.白天大气加热率和夜晚大气冷却率的平均值都基本相当,印证了大气能量守恒.
By using the radiosonde data, the heating rate and cooling rate characteristics of atmosphere boundary layer over the North Tibet Plateau in summer are analyzed. It is found that over the North Tibet Plateau in summer, the interdiurnal variations of heating rate and cooling rate of PBLare conspicuous, and the values are larger in clear day than that in cloudy and rainy day; the mean heating rate during daytime is equivalent with the mean cooling rate during night, which proves the conservation of energy.
