RISObjectively Assessing Characteristics of Mesoscale Convective Organization in an Operational Convection-Permitting Model
Publisher: American Meteorological Society
Coupling between Gravity Waves and Tropical Convection at Mesoscales
Publisher: American Meteorological Society
Abstract: n idealized cloud-system-resolving model simulation is used to examine the coupling between a tropical cloud population and the mesoscale gravity waves that it generates. Spectral analyses of the cloud and gravity wave ...
Long-Lived Mesoscale Systems in a Low–Convective Inhibition Environment. Part I: Upshear Propagation
Publisher: American Meteorological Society
Abstract: ynamical models of organized mesoscale convective systems have identified the important features that help maintain their overarching structure and longevity. The standard model is the trailing stratiform archetype, featuring ...
A 10-Year Austral Summer Climatology of Observed and Modeled Intraseasonal, Mesoscale, and Diurnal Variations over the Maritime Continent
Publisher: American Meteorological Society
Abstract: AbstractThe Maritime Continent is one of the wettest regions on the planet and has been shown to be important for global budgets of heat and moisture. Convection in the region, however, varies on several interrelated scales, ...
Some Influences of Background Flow Conditions on the Generation of Turbulence due to Gravity Wave Breaking above Deep Convection
Publisher: American Meteorological Society
Abstract: Deep moist convection generates turbulence in the clear air above and around developing clouds, penetrating convective updrafts and mature thunderstorms. This turbulence can be due to shearing instabilities caused by strong ...
Convectively Generated Gravity Waves and Their Effect on the Cloud Environment
Publisher: American Meteorological Society
Abstract: This study uses a two-dimensional cloud-resolving model to examine how convectively generated gravity waves modify the environment of an isolated convective cloud. The model is initialized with an idealized sounding, and ...
Toward an Understanding of Vertical Momentum Transports in Cloud-System-Resolving Model Simulations of Multiscale Tropical Convection
Publisher: American Meteorological Society
Abstract: his study examines the characteristics of convective momentum transport (CMT) and gravity wave momentum transport (GWMT) in two-dimensional cloud-system-resolving model simulations, including the relationships between the ...
Long-Lived Mesoscale Systems in a Low–Convective Inhibition Environment. Part II: Downshear Propagation
Publisher: American Meteorological Society
Abstract: art II of this study of long-lived convective systems in a tropical environment focuses on forward-tilted, downshear-propagating systems that emerge spontaneously from idealized numerical simulations. These systems differ ...
On the Identification of the Large-Scale Properties of Tropical Convection Using Cloud Regimes
Publisher: American Meteorological Society
Abstract: he use of cloud regimes in identifying tropical convection and the associated large-scale atmospheric properties is investigated. The regimes are derived by applying cluster analysis to satellite retrievals of daytime-averaged ...
Sensitivities of Orographic Precipitation to Terrain Geometry and Upstream Conditions in Idealized Simulations
Publisher: American Meteorological Society
Abstract: his study examines how variations in relatively simple terrain geometries influence orographic precipitation and its spatial patterns of sensitivity to small changes in upstream conditions. An idealized three-dimensional ...
