RISHadley Circulations in Radiative–Convective Equilibrium in an Axially Symmetric Atmosphere
Publisher: American Meteorological Society
Abstract: Hadley circulations in radiative?convective equilibrium are investigated using an idealistic axially symmetric model. Calculations show that the distribution of temperature in the Hadley cell is controlled by the moist ...
Conservative Scheme for the Compressible Nonhydrostatic Models with the Horizontally Explicit and Vertically Implicit Time Integration Scheme
Publisher: American Meteorological Society
Abstract: A new dynamical scheme with the conservative forms of the equations of density, momentum, and internal energy is proposed for the nonhydrostatic models. With this scheme, the conservations of the mass and the total energy ...
Conservative Scheme for a Compressible Nonhydrostatic Model with Moist Processes
Publisher: American Meteorological Society
Abstract: A conservative scheme for a compressible nonhydrostatic model including moist processes is formulated and is tested for experiments involving a squall line. The scheme is based on the flux form equations of total density, ...
Statistics on High-Cloud Areas and Their Sensitivities to Cloud Microphysics Using Single-Cloud Experiments
Publisher: American Meteorological Society
Abstract: Statistics on high-altitude cloud areas associated with deep cumulus clouds and their sensitivities to cloud microphysics are studied in the framework of single-cloud experiments with an explicit cloud system?resolving ...
On the Warm Core of a Tropical Cyclone Formed near the Tropopause
Publisher: American Meteorological Society
Abstract: n the basis of numerical results of a three-dimensional model diagnosed using balance dynamics, a mechanism by which the upper-level warm core of tropical cyclones (TCs) forms is proposed. The numerical results reveal that ...
Response of Ice and Liquid Water Paths of Tropical Cyclones to Global Warming Simulated by a Global Nonhydrostatic Model with Explicit Cloud Microphysics
Publisher: American Meteorological Society
Abstract: loud feedback plays a key role in the future climate projection. Using global nonhydrostatic model (GNHM) simulation data for a present-day [control (CTL)] and a warmer [global warming (GW)] experiment, the authors estimate ...
Dynamical Roles of Mixed Rossby–Gravity Waves in Driving Convective Initiation and Propagation of the Madden–Julian Oscillation: General Views
Publisher: American Meteorological Society
Abstract: Motivated by the previous case study, this work shows that dynamical variations of mixed Rossby–gravity waves with tropical depression-type circulations (MRGTDs) are one possible drivers of convective initiation and ...
A Synoptic-Scale Cold-Reservoir Hypothesis on the Origin of the Mature-Stage Super Cloud Cluster: A Case Study with a Global Nonhydrostatic Model
Publisher: American Meteorological Society
Abstract: his chapter proposes a working assumption as a way of conceptual simplification of the origin of Madden?Julian oscillation (MJO)-associated convection, or super cloud cluster (SCC). To develop the simplification, the ...
Evaluation of Precipitating Hydrometeor Parameterizations in a Single-Moment Bulk Microphysics Scheme for Deep Convective Systems over the Tropical Central Pacific
Publisher: American Meteorological Society
Abstract: loud microphysics of deep convective systems over the tropical central Pacific simulated by a cloud system?resolving model using satellite simulators are evaluated in terms of the joint histogram of cloud-top temperature ...
Diversity of the Madden–Julian Oscillation: Initiation Region Modulated by the Interaction between the Intraseasonal and Interannual Variabilities
