摘要
Rossby在“从局地高空纪录估计天气”一文中引用高空变压与地面变压的关系■(1)上式p_(0)是地面壓力,p是高空z处的壓力,P爲中間空氣柱的平均密度,C爲風速,θ爲風向舆东向所成的角度,■爲風向量用極坐標繪出所包括面積的两倍.
The method of the computation of the upper-air tendency field due to Rossby[1]and Miller and Thompson[2]is marred by their arbitrarily cutting off of some terms wihch appear to be of the same order of magnitude but of the opposite sign.It is difficult,or practically impossible,to justify their method theoretically.In this paper,instead of using the equation of continuity as they have done,-we employ the advective conservation of temperature for the derivation d the upper-air tendency field.It is ismilar but with some corrections.It is proposed that this formula(10),instead of their orginal formula,may be used with advantage for the work.
