Abstract
The ice water content (IWC) distribution in a mixed-phase cloud system was investigated using CloudSat data, aircraft measurements, and the Weather Research and Forecasting (WRF) model. Simulated precipitation and IWC were in general agreement with rain gauge, satellite, and aircraft observations. The cloud case was characterized by a predominant cold layer and high IWC throughout the cloud-development and precipitation stages. The CloudSat-retrieved products suggested that the IWC was distributed from 4.0 to 8.0 km, with the maximum values (up to 0.5 g m-3) at 5.0-6.0 km at the earlymature stage of cloud development. High IWC (up to 0.8 g m-3) was also detected by airborne probes at 4.2 and 3.6 km at the late-mature stage. The WRF model simulation revealed that the predominant riming facilitated rapid accumulation of high IWC at 3.0-6.0 km.
