【摘要】 本文提出了1000mb 面及500mb 面图解法数值预报的新方法.其特点是:(1)考虑了整个对流圈的铅直结构.用 Sawyer-Bushby 模式进行计算;但方法可推广到其他模式,例如Eliassen 模式.(2)500mb 面不当作无辐散层,无辐散层可置于其他适当的等压面上.方法的要点是利用 Bolin 定义的等效斜压层上某些平流来计算1000mb 及500mb 面的变高.讨论了一些实际试验结果.更多还原

【Abstract】 A new method of preparing 1000 mb and 500 mb prognostic charts bygraphical integration is proposed.Its main features are:(1)The verticalstructure of whole troposphere is taken into consideration.Sawyer-Bushby’smodel is used in actual computation;but the method can be extended to othermodels,e.g.Eliassen’s model.(2)500 mb surface is not taken as the levelof non-divergence,which may be placed at other appropriate isobaric surface.The proposed method consists essentially in calculating the height changes of1000 mb and 500 mb surfaces by means of certain advections on equivalentbaroclinic levels defined by Bolin.Some results of the experiment are discussed.更多还原
