Abstract: An axisymmetric warm cloud model including 36 classes of droplets from 1 to 4096 ?m is developed. A reference spectrum is prescribed for the formation of droplets around condensation nuclei. Other microphysical processes ...

Abstract: Axisymmetric and slab-symmetric cumulus cloud models with Kessler's parameterizations for microphysical processes are developed. By using a staggered grid arrangement and applying a modified upstream difference scheme, ...

Abstract: A cumulus cloud population is determined over the trade-wind region under an undisturbed weather condition from the large-scale heat and moisture budgets. The BOMEX data during the period 22?23 June 1969 are used. Six ...

Abstract: The vertical transport of horizontal momentum in a convective tropical rainband is studied using a two-dimensional cloud ensemble model. Twelve simulations are made under the same large-scale conditions. The vertical ...

Abstract: A three-dimensional numerical cloud ensemble model has been developed to investigate the collective feedback effects of cloud systems on the large-scale environment. An observed large-scale lifting is imposed continuously ...

Abstract: Short-period cycles in the large-scale atmospheric circulation were investigated with time series of kinetic energy, its generation and outflow, which were computed twice a day for a 5-year period over the North American ...

Abstract: Two- and three-dimensional configurations of a cloud ensemble model are used to study the statistical properties of cloud ensembles under an observed large-scale condition. The basic design of the model has been presented ...

Abstract: A two-dimensional, time-dependent, and nonhydrostatic numerical cloud model is used to study the development and structure of a subtropical squall line that occurred during TAMEX (Taiwan Area Mesoscale Experiment). The ...

Abstract: A numerical cloud model is used to evaluate the performance of several ice parameterizations. Results from simulations using these schemes are contrasted with each other, with an ice-free control simulation, and with ...

Abstract: he Weather Research and Forecasting (WRF) model is evaluated by conducting various sensitivity experiments over central California including the San Francisco Bay Area (SFBA), with the goal of establishing a WRF model ...
