摘要
对位涡概念发展史进行了总结并给出位涡反演原理 ,讨论了不同近似模式的位涡表达式及其拉格朗日守恒形式 ;对位涡特性研究方面的新成果作了总结 ;考察大量应用实例并指出存在的不足 ;
The history of potential vorticity developments is reviewed and the invertibility principle for potential vorticity is presented. We discuss the various versions of potential vorticity and the Lagrangian conservation properties in the differently approximate models. Some new properties of potential vorticity are summarized. Several methods of potential vorticity inversion are discussed and compared. A lot of examples are examined and their disadvantage are also investigated. We conclude the remark by predicting some possible applications of the IPV concept and potential vorticity inversion.
