Responses of Shallow Cumulus Convection to Large - scale 1 Temperature and Moisture Perturbations : a comparison of 2 large - eddy simulations and a convective parameterization based
7 Responses of shallow cumuli to large-scale temperature/moisture perturbations are examined 8 through diagnostics of large-eddy-simulations (LES) of the undisturbed Barbados Oceano9 graphic and Meteorological Experiment (BOMEX) case and a stochastic parcel model. The 10 perturbations are added instantaneously and allowed to evolve freely afterwards. The par11 cel model reproduces most of the c...
متن کاملResponses of Shallow Cumulus Convection to Large-Scale Temperature and Moisture Perturbations: A Comparison of Large-Eddy Simulations and a Convective Parameterization Based on Stochastically Entraining Parcels
Responses of shallow cumuli to large-scale temperature/moisture perturbations are examined through diagnostics of large-eddy simulations (LESs) of the undisturbed Barbados Oceanographic and Meteorological Experiment (BOMEX) case and a stochastic parcel model. The perturbations are added instantaneously and allowed to evolve freely afterward. The parcel model reproduces most of the changes in th...
متن کاملThe Environment of Precipitating Shallow Cumulus Convection
Quantitative estimates of precipitation in a typical undisturbed trade wind region are derived from 2 months of radar reflectivity data and compared to the meteorological environment determined from soundings, surface flux, and airborne-lidar data. Shallow precipitation was ubiquitous, covering on average about 2% of the region and contributing to at least half of the total precipitation. Echo ...
متن کاملreview of cumulus convective parameterization schemes in large and meso- scale models
cumulus convection, as a meso-scale phenomenon, results in the release of latent heat and vertical drift of energy that by part could affect the large scale field of energy, humidity, and momentum of the atmosphere. since the current numerical models are unable to resolve the singular cumulus convective clouds that are important from a meteorological point of view, it is used to apply some sort...
متن کاملEvaluation of the atmospheric transport in a GCM using radon measurements: sensitivity to cumulus convection parameterization
The radioactive species radon (222Rn) has long been used as a test tracer for the numerical simulation of large scale transport processes. In this study, radon transport experiments are carried out using an atmospheric GCM with a finite-difference dynamical core, the van Leer type FFSL advection algorithm, and two state-of-the-art cumulus convection parameterization schemes. Measurements of sur...
