根據廣州上空氣球升速与大氣層結構之關係推斷大氣垂直運動

A STUDY OF VERTICAL MOTION IN RELATION TO DEEP STABLE STRATIFIED LAYERS IN WINTER IN CANTON DERIVED BY MEANS OF THE ASCENSIONAL RATE OF RASONDE SYSTEM

摘要: 当氣球無洩氣情况時,300毫巴以下每升高4公里升速約增加7-8%。根據風洞及实驗大氣中氣球升速特性之实驗,指出C为雷諾数R之函数。对C來说,R有一臨界值,当R处於臨界區内,C隨R減少而增加极快,因之氣球升速也当隨R之減少而激烈下降。当R处於臨界區以外C可看為常数。

Abstract: In the winter of 1945-46,there existed frequently a deep stable layer (|∂T/∂z|<0.3℃/100M) in the lower troposphere.The upper houndary of this stable layer was at a height of about 3-4km and the lower boundary might reach the ground It was very of tenthat there might be another deep stable layer in the middle or unoer troposphere.The original data of rawind and rasonde svstems showed that as the balloons passing through these layers the rate of ascent changed noticeably.
