Ambient Wind Effects on the Initiation and Development of Cumulus Clouds over Mountains
Publisher: American Meteorological Society
Abstract: The effects of ambient winds on the initiation and development of cumulus clouds over mountains are investigated. A case with the atmosphere initially at rest is compared with a case in which a wind increasing linearly ...
EFFECTS OF HIGHER ORDER ADVECTION TECHNIQUES ON A NUMERICAL CLOUD MODEL
Publisher: American Meteorological Society
Abstract: Crowley's second- and fourth-order nonconservative techniques for treating the advection term in numerical solutions of the hydrothermodynamic equations are tested on a model of cumulus cloud growth over mountains. The ...
Numerical Modeling of Precipitation and Cloud Shadow Effects on Mountain-Induced Cumuli
Publisher: American Meteorological Society
Abstract: The effects of precipitation on a model of cumulus cloud initiation and development over mountains are studied by numerically integrating the equations of motion, equations of conservation of water substance, and the ...
Numerical Modeling of Hailstorms and Hailstone Growth. Part I: Preliminary Model Verification and Sensitivity Tests
Publisher: American Meteorological Society
Abstract: This paper is the first in a three part series describing numerical simulations of hailstorms and hailstone growth using a two-dimensional, time-dependent cloud model. In this model. cloud water, cloud ice and rain are ...
A Numerical Model of a Hail-Bearing Cloud
Publisher: American Meteorological Society
Abstract: A numerical model of a hail-bearing cumulus cloud is presented. The model is one-dimensional and time-dependent, and it employs extensive parameterization of the microphysical processes. The raindrop and hailstone size ...
Numerical Simulation of a 4-Day Early Spring Storm Period in the Black Hills
Publisher: American Meteorological Society
Abstract: This paper illustrates the potential for mesoscale models to depict the distribution of precipitation in orographic situations. The study covers a 4-day time period in April 1995. The domain of the numerical model covers ...
Radar Reflectivity Factor Calculations in Numerical Cloud Models Using Bulk Parameterization of Precipitation
Publisher: American Meteorological Society
Abstract: This paper describes and compares various methods for calculating radar reflectivity factors in numerical cloud models that use bulk methods to characterize the precipitation processes. Equations sensitive to changes in ...
