Microphysical Processes in Precipitation Mechanism

Microphysical and Dynamical Characteristics of Low-Precipitation and Classic Supercells

The sensitivity of supercell morphology to the vertical distribution of moisture is investigated in this study using a cloud-resolvingmodel with 300-mhorizontal grid spacing. Simulated storms are found to transition from classic (CL) to low-precipitation (LP) supercells when the strength of elevated dry layers in the environmental moisture profile is increased. Resulting differences in themicro...

Precipitation and microphysical processes observed by three polarimetric X-band radars and ground-based instrumentation during HOPE

This study presents a first analysis of precipitation and related microphysical processes observed by three polarimetric X-band Doppler radars (BoXPol, JuXPol and KiXPol) in conjunction with a ground-based network of disdrometers, rain gauges and vertically pointing micro rain radars (MRRs) during the High Definition Clouds and Precipitation for advancing Climate Prediction (HD(CP)2) Observatio...

Radar observations of the kinematic, microphysical, and precipitation characteristics of two MCSs in TRMM LBA

[1] Dual-Doppler and polarimetric radar observations are used to analyze two mesoscale convective systems (MCSs) that occurred during the Tropical Rainfall Measuring Mission Large-Scale Biosphere-Atmosphere field campaign. The MCSs formed in different meteorological regimes, based on profiles of atmospheric wind and thermodynamic data. The first MCS event (26 January 1999) was a squall line tha...

Precipitation processes in the Middle East

A regional climate model, RegCM2, is used to investigate the relative importance of storm tracks and topography in generating precipitation in the Middle East. The model is run for five years (1990 thru 1994) at 25km horizontal resolution forced at the boundaries by the ECMWF-TOGA analysis. Six subregions that exhibit precipitation regimes disparate from one-another are identified and examined....
