Abstract: Arakawa and Schubert?s cumulus parameterization is formulated under the two asymptotic limits: σ ? 0 and τc/τL ? 0, where σ is the fractional area occupied by cumulus convection, and τc and τL are the characteristic ...

Abstract: The Wind-Induced Sea?Air Heat Exchange (WISHE) Model of the 30?60-day oscillation developed by Emanuel is improved by adding downdrafts to the representation of convection and by coupling the troposphere to a passive ...

Abstract: A systematic scale analysis is performed for large-scale dynamics over the tropics. It is identified that two regimes are competing: 1) a dynamics characterized by balance between the vertical advection term and diabatic ...

Abstract: he present paper presents a simple theory for the transformation of nonprecipitating, shallow convection into precipitating, deep convective clouds. To make the pertinent point a much idealized system is considered, ...

Abstract: AbstractThe Madden?Julian oscillation (MJO), a planetary-scale eastward-propagating coherent structure with periods of 30?60 days, is a prominent manifestation of intraseasonal variability in the tropical atmosphere. It ...
