摘要
综合分析罗斯贝、辛普森、拉欣和桑德斯等关于空气的干绝热和湿绝热过程的研究,从定义出发,严格推出罗-辛假相当位温(θses)的精确计算公式,包含罗斯贝假相当位温(θse)与辛普森假相当位温(θss),编制出5种假相当位温变量表,对比分析了文献[12]及其计算结果与本文相应结果的差异,并分析指出差异的原因。
The present study analyzed the research of Rossby, Simpson, Lasheen and Saunders on dryadiabatic process and wet-adiabatic process of atmosphere and proposed the accurate formula of Rossby-Simpson pseudo-equivalent potential temperature base on the definition. The formula included the Rossby pseudo-equivalent potential temperature(θse) and the Simpson pseudo-equivalent potential temperature(θss).Five checking tables were presented, and the reason why the values differed from that of previous studies was discussed.
