This study examines the impact of three-dimensional variational data assimilation (3DVAR) on prediction two heavy rainfall events over Southern China by using a real-time storm-scale forecasting system. Initialized from European Centre for Medium-Range Weather Forecasts (ECMWF) high-resolution data, system is characterized combining Advanced Research and Forecasting (WRF-ARW) model Regional Prediction System (ARPS) 3DVAR package. Observations Doppler radars, surface Automatic Station (AWS)...
This study presented airborne measurements of ice particle properties in three stratiform precipitating clouds over northern China. By using horizontal observations at selected altitudes, the distributions water content (IWC), habits, and size spectrum parameters were investigated. The cloud cases characterized by high IWC values due to existence embedded convective cells. Liquid contents rather low with maxima less than 0.3 g m −3 general 0.1 . occurrence large dendritic crystals as well...
In this study, we investigated the macro- and microstructures of layered precipitation clouds in spring Jilin Province, China. The premise campaign was to observe cloud particles melting layer (ML). weather developed under influence Mongolia cyclone, which brought a large range northeast. Combining Droplet Measurement Technology (DMT) Particle Measuring Systems (PMS) data, small accounted for majority all at each level above below ML. our observations, both ice crystals (50–300 μm)...
Based on cloud-probe data and airborne Ka-band cloud radar collected in Baoding 5 August 2018, the microphysical structural characteristics of cumulus (Cu) at precipitation stage were investigated. The droplets Cu found to be significantly larger than those stratiform (STF) cloud. In cloud, most particles between 7 10 μm diameter, while STF majority grew no 2 μm. sensitivity properties aerosols varied with height. droplet effective radius showed a negative relationship aerosol number...
Abstract As a key factor influencing the cloud life cycle and radiative properties, liquid‐ice mass partitioning remains major source of uncertainties in modeling mixed‐phase clouds. One unresolved problems is that mixing highly inhomogeneous, but it has not been well understood quantified for parameterization. In this study, homogeneity ( χ ) using information‐theoretic entropy based on airborne measurements. It demonstrated positively correlated with condensed water content (CWC). Cloud...
Abstract A fast inverse algorithm based on the half-V cycle scheme (HV) of multigrid technique is developed for cloud tomography. Fourier analysis shows that slow convergence problem caused by smoothing property iterative can be effectively alleviated in HV performing iterations from coarsest to finest grid. In this way, resolvable scales information contained observations retrieved efficiently coarser grid level and unresolvable are left as errors finer level. Numerical simulations indicate...
The ice crystal habits, distributions and growth processes in two snowfall cloud cases on 29 November 2009 3 March 2012 northern China were compared analyzed with aircraft data. results showed that habits affected by the height of clouds. Ice crystals clouds top temperatures −12.6 °C predominantly needle, plate, dendrite irregular. When temperature was lower than −19.5 °C, plates, dendrites irregular observed addition to needles, capped-column middle layers clouds, column upper layer liquid...
Pulse hailstorms over southwestern China generally produce small hailstones with diameters less than 20 mm, causing considerable damage to crops such as tobacco and cotton. This study examines the mechanisms behind typical pulse which frequently occur in plateau regions China. Utilizing radar observations Cloud Model 1 (CM1) numerical model, influence of environmental factors on associated is investigated. The results indicate that: firstly, are primarily generated from frozen droplets,...
