%0 Journal Article %T On derivation and interpretation of Kuo-Eliassen equation %A Jun-Ichi Yano %J Journal of Advances in Modeling Earth Systems %D 2011 %I %R 10.1029/2011ms000058 %X The Kuo¨CEliassen equation provides a balance condition for both tropical¨Ccyclone like vortex systems as well as zonally¨Csymmetric meridional circulations. This condition is examined with the former application more in mind. The condition is derived more ped- agogically based on the bounded derivative method. Some physical interpretations as well as basic mathematical remarks on this condition are provided. Analogy with quasi¨Cgeostrophic system is also remarked. %K tropical cyclone dynamics %U http://james.agu.org/index.php/JAMES/article/view/v3n2
