Abstract: Climatologically, the equatorial western Pacific warm pool region is a local minimum in surface evaporation and a local maximum in precipitation. The moist static energy budget in this situation requires a collocated minimum ...

Abstract: In zonally averaged chemical transport models of the stratosphere, quasi-isentropic mixing is represented by diffusion in latitude. However, it is fairly certain that the real mixing is to some extent nonlocal, so that the ...

Abstract: single-column modeling approach is proposed to study the interaction between convection and large-scale dynamics using the quasigeostrophic (QG) framework. This approach extends the notion of ?parameterization of large-scale ...

Abstract: This study discusses the direct diagnosis of stratosphere?troposphere exchange. The method introduced by Wei is applied to the Goddard Earth Observation System assimilated dataset. In many respects, the results generally ...

Abstract: This paper examines the influence of imposed drying, intended to represent horizontal advection of dry air, on parameterized deep convection interacting with large-scale dynamics in a single-column model framework. Two ...

Abstract: bservational studies suggest that the stratospheric quasi-biennial oscillation (QBO) can modulate tropical deep convection. The authors use a cloud-resolving model with a limited domain, representing a convective column ...

Abstract: A model of intermediate complexity based on quasi-equilibrium theory?a version of the Quasi-Equilibrium Tropical Circulation Model with a prognostic atmospheric boundary layer, as well as two free-tropospheric modes in ...

Abstract: The authors introduce a simple model for the time-dependent evolution of tropical ?hot spots,? or localized regions where the sea surface temperature (SST) becomes unusually high for a limited period of time. The model ...

Abstract: A simple coupled model is used in a zonally symmetric aquaplanet configuration to investigate the effect of ocean?atmosphere coupling on the Asian monsoon intraseasonal oscillation. The model consists of a linear atmospheric ...

Abstract: The authors investigate the influence of western North Pacific (WNP) tropical cyclones (TCs) on their large-scale environment by lag regressing various large-scale climate variables [atmospheric temperature, winds, relative ...
