[AOS29-06] Formulation and application of phase-independent evergy conversions for quasi-geostrophic eddies
Keywords:quasi-geostrophic eddy, energy conversion, low-frequent variability in the extra-tropics
In this study, a new formulation of energy conversions for quasi-geostrophic eddies is proposed under an assumption that a eddy is almost a plane wave in the WKB sense. Because of a phase-independent form, the new formulation can be applicable to estimating energy conversions for stationary eddies or snapshot of transient eddies. Actual applications of the new form of the energy conversions to the data analysis will also be given.
