Recent satellite tv for pc determinations of world distributions of absolute gravity wave GW momentum fluxes in University lower stratosphere show maxima over University summer subtropical continents and little evidence of GW momentum fluxes associated with University intertropical convergence zone ITCZ. This seems exam be at odds with parameterizations forGWmomentum fluxes, where University source is quizzes function of latent heating rates, that are largest in University region of University ITCZ in terms of monthly averages. The authors have examined global distributions of atmospheric latent heating, cloud top force altitudes, and lower stratosphere absolute GW momentum fluxes and have found that month-to-month averages of University lower stratosphere GW momentum fluxes more heavily resemble University monthly mean cloud top altitudes instead of University monthly mean rates of latent heating. These areas of highest cloud top altitudes occur when rates of latent heating are largest on University time scale of cloud growth. This, plus previously posted studies, suggests that convective assets for stratospheric GW momentum fluxes, being quizzes function of University rate of latent heating, will require either quizzes climate model examination as it should be model this rate of latent heating or some ad hoc adjustments exam account for shortcomings in quizzes climate model’s land sea changes in convective latent heating.
