TLDR
In this article, the mesoscale organization of precipitation, the structures of the clouds, the air flows associated with mesoscales, and the precipitation efficiencies and the mechanisms producing precipitation in the rainbands associated with a cold front were deduced.Abstract:
Detailed information is deduced on the mesoscale organization of precipitation, the structures of the clouds, the air flows associated with mesoscale rainbands, and the precipitation efficiencies and the mechanisms producing precipitation in the rainbands associated with a cold front. Measurements were obtained with quantitative reflectivity and Doppler radars, two instrumented aircraft, serial rawinsondes and a network of ground stations. The regions of heaviest precipitation were organized into a complex mesoscale rainband in the warm-sector air ahead of the front, a narrow band of precipitation at the surface cold front, and four wide cold-frontal rainbands. The wide cold-frontal rainbands and the smaller mesoscale areas of precipitation within them moved with the velocities of the winds between ∼3—6 km. The narrow rainband, which was produced by strong convergence and convection in the boundary layer, moved with the speed of the cold front at the surface. A coupled updraft and downdraft was p...read more

Factors Determining the Impact of Aerosols on Surface Precipitation from Clouds: An Attempt at Classification
TL;DR: In this article, the dynamics and microphysics of clouds observed during the Large-Scale Biosphere-Atmosphere Experiment in Amazonia-Smoke, Aerosols, Clouds, Rainfall, and Climate (LBA-SMOCC) campaign, as well as extremely continental and extremely maritime clouds, are performed using an updated version of the Hebrew University spectral microphysical cloud model (HUCM).

Organization of clouds and precipitation in extratropical cyclones
TL;DR: A number of models accounting for the distribution of cloud and precipitation in extratropical cyclones were proposed during the 19th and early 20th centuries as mentioned in this paper, and these models culminated in the classical Norwegian polar-front cyclone model of the Bergen school.

TL;DR: In this article, the improvement of microphysical parameterization through Observational Verification Experiment (IMPROVE) was proposed to evaluate and improve the microphysical processes and hydrometeor fields simulated by BMP schemes.

TL;DR: In this article, a general circulation model called "AFES" has been fully optimized to the unique architecture of the Earth Simulator, to attain extremely high com- putational efficiency, and the ultra-high resolution global simulations with AFES are able to explicitly represent interaction among planetary, synoptic and meso-scale phenomena and the topographic modulation of mesoscale precipitation.
