Abstract: linear stochastic model is presented for the dynamics of water vapor and tropical convection. Despite its linear formulation, the model reproduces a wide variety of observational statistics from disparate perspectives, ...

Abstract: Cumulus clouds involve processes on a vast range of scales?including cloud droplets, turbulent mixing, and updrafts and downdrafts?and it is often difficult to determine how processes on different scales interact with each ...

Abstract: quatorial long-wave theory applies where a small horizontal aspect ratio between meridional and zonal length scales is assumed. In an idealized setting, the theory suggests that (i) meridional wind is small, (ii) geostrophic ...

Abstract: Convective momentum transport (CMT) plays a central role in interactions across multiple space and time scales. However, because of the multiscale nature of CMT, quantifying and parameterizing its effects is often a ...

Abstract: It is known that gravity waves in the troposphere, which are often excited by preexisting convection, can favor or suppress the formation of new convection. Here it is shown that in the presence of wind shear or barotropic ...

Abstract: simple stochastic model is designed and analyzed in order to further understand the transition to strong convection. The transition has been characterized recently in observational data by an array of statistical measures, ...

Abstract: minimal, nonlinear oscillator model is analyzed for the Madden?Julian oscillation (MJO) ?skeleton? (i.e., its fundamental features on intraseasonal/planetary scales), which includes the following: (i) a slow eastward phase ...

Abstract: AbstractPrecipitating versions of the quasigeostrophic (QG) equations are derived systematically, starting from the equations of a cloud-resolving model. The presence of phase changes of water from vapor to liquid and vice ...

Abstract: he Madden?Julian oscillation (MJO) skeleton model offers a theoretical prediction of the MJO?s structure. Here, a method is described for identifying this structure in observational data. The method utilizes projections ...

Abstract: onvectively coupled equatorial waves (CCEWs) are often identified by space?time filtering techniques that make use of the eigenvalues of linear shallow water theory. Here, instead, a method is presented for identifying ...
