RISFeedback of Deep Moist Convection to Its Near Environment as Diagnosed from Three-Dimensional Numerical Model Output. Results from an Early Experiment
Publisher: American Meteorological Society
Abstract: This paper presents preliminary results from an investigation into the feedback between convective storms and their new surroundings, using output from a three-dimensional anelastic cloud-scale model. Convective feedback ...
A Three-Dimensional Numerical Model of an Isolated Thunderstorm. Part II: Dynamics of Updraft Splitting and Mesovortex Couplet Evolution
Publisher: American Meteorological Society
Abstract: This study analyzes the dynamics of an isolated convective storm embedded within marked ambient vertical wind shear dominated by low-level veering, as simulated by a three-dimensional anelastic numerical modeling experiment. ...
Overshooting Thunderstorm Cloud Top Dynamics as Approximated by a Linear Lagrangian Parcel Model with Analytic Exact Solutions
Publisher: American Meteorological Society
Abstract: This Paper Presents results for a linear Lagrangian entraining parcel model of an overshooting thunderstorm cloud top. The model is based on that of Adler and Mack, but differs in that it achieves analytic, exact solutions ...

Mature Thunderstorm Cloud-Top Structure and Dynamics: A Three-Dimensional Numerical Simulation Study
Publisher: American Meteorological Society
Abstract: An anelastic three-dimensional model is used to investigate the effects of vertical wind shear regime on cloud-top structure and internal properties of mature isolated midlatitude thunderstorms. Four comparative experiments, ...
Effects of the Pressure Perturbation Field in Numerical Models of Unidirectionally Sheared Thunderstorm Convection: Two versus Three Dimensions
Publisher: American Meteorological Society
Abstract: Two- and three-dimensional anelastic numerical modeling experiments with common environmental profiles are used to study two aspects of the pressure perturbation field in strongly sheared convective storms: 1) the physical ...
A Numerical Model of Deep Moist Convection: Part II. A Prototype Experiment and Variations Upon It
Publisher: American Meteorological Society
Abstract: This study involves the dynamics of a deep convective cloud in conditionally unstable surroundings with moderate mid-tropospheric shear. A two-dimensional, anelastic numerical model is used to simulate convection of the ...
