Abstract: For a linearized system such as ??/?t = ??, singular vector analysis can be used to find patterns that give the largest or smallest ratios between the sizes of ?? and ?. Such analyses have applications to a wide range of ...

Abstract: Gross moist stability (GMS), a measure of how efficiently divergent flow exports column-integrated moist static energy (MSE), is a widely used quantity in current simplified models of the tropical mean circulation and ...

Abstract: An approach is presented for the construction of linear response functions of a cumulus ensemble to large-scale temperature and moisture perturbations using a cloud system?resolving model (CSRM). A set of time-invariant, ...

Abstract: ock Walker cells driven by weak sea surface temperature (SST) forcing are studied using planetary-scale cloud system?resolving simulations and a simplified framework that represents convection with its linear response ...

Abstract: A limited-domain cloud system?resolving model (CSRM) is used to simulate the interaction between cumulus convection and two-dimensional linear gravity waves, a single horizontal wavenumber at a time. With a single horizontal ...

Abstract: A simple model of two vertical modes is constructed and analyzed to reveal the basic instability mechanisms of convectively coupled waves. The main novelty of this model is a convective parameterization based on the ...

Abstract: AbstractA procedure is presented to systematically construct simple models for the linear stability of moist convecting atmospheres. First, linear response functions of a cumulus ensemble constructed from cloud-system-resolving ...

Abstract: AbstractThe linear response function (LRF) of an idealized GCM, the dry dynamical core with Held?Suarez physics, is used to accurately compute how eddy momentum and heat fluxes change in response to the zonal wind and ...
