中文摘要:
      天气分析,为近年来气象学上最大之收获,气团之分布,与极面之移动既明,则短期预告,自较昔日仅凭经验之法则为准确。惟地面观测常以种种影响而不得明其真相。是故高空测候,因以日见发达。天气之预测,乃由地面之观察,进而为三度之分析。我国测候事业,尚在草创时期。测候所可用者数不满百,高空纪录,尤感缺乏。
英文摘要:
      At 2pm 16th of March,the cold Ps(Polar Siberian) air mass was on the way to invade China Proper. The discontinuity as seen by wind direction along the cold fronts extended from Inner mnngolia to North China, The warm front treaded SW-ward at a distance of about 200km, west of Nanking. The temperature in the warn setter ranged from 15℃, to 20℃,while that to the east of the front was mostly five to ten degrees lower, As showen by the sounding balloon observation taken at Pei-Chi-Ko in the afternoon of the 16th, the frontal inversion was 3,330m, in height over Nankingt which was nearly the height of A-St, observed by the pilot balloon simultaneously, The layers, from the surface to 2.22km and from 3.05km, to 3.33km, were in conditional instability, But that from 2.22km, to 3.05km, was absolutely stable, The moist and cool Yp (Polar Pacific)air mass below the frontal inversion seems to be NPs (transformed Polar Siberian),which returned from the relatively warm ocean as a SW-ly or SE-ly current, Above this inversions the tropical air mass was is a state of absolute stability which was probably due to the modification during its N-ward journey, This may explain why no preci pitation was raceived in the regions to north of the Yangtze during the passage of the frontal systems.
