RISUtilizing Spaceborne Radars to Retrieve Dry Snowfall
Publisher: American Meteorological Society
Abstract: A dataset consisting of one year of CloudSat Cloud Profiling Radar (CPR) near-surface radar reflectivity Z associated with dry snowfall is examined in this study. The CPR observations are converted to snowfall rates S using ...
The Structure and Evolution of a Numerically Simulated High-Precipitation Supercell Thunderstorm
Publisher: American Meteorological Society
Abstract: The structure and evolution of a high-precipitation (HP) supercell thunderstorm is investigated using a three-dimensional, nonhydrostatic, cloud-scale numerical model (TASS). The model is initialized with a sounding taken ...
Global Distribution of Snow Precipitation Features and Their Properties from 3 Years of GPM Observations
Publisher: American Meteorological Society
Abstract: AbstractUsing a 3-yr Global Precipitation Mission (GPM) Ku-band Precipitation Radar (KuPR) dataset, snow features (SFs) are defined by grouping the contiguous area of nonzero solid precipitation. The near-surface wet bulb ...
Mechanisms of Cell Regeneration, Development, and Propagation within a Two-Dimensional Multicell Storm
Publisher: American Meteorological Society
Abstract: In this study, mechanisms of cell regeneration, development, and propagation within a two-dimensional multicell storm are investigated using a numerical cloud model. The cell regeneration is explained by the advection ...
Uncertainty Analysis for CloudSat Snowfall Retrievals
Publisher: American Meteorological Society
Abstract: A new method to derive radar reflectivity?snow rate (Ze?S) relationships from scattering properties of different ice particle models is presented. Three statistical Ze?i relationships are derived to characterize the best ...
Scattering of Ice Particles at Microwave Frequencies: A Physically Based Parameterization
Publisher: American Meteorological Society
Abstract: This paper presents a new, purely physical approach to simulate ice-particle scattering at microwave frequencies. Temperature-dependent ice particle size distributions measured by aircraft in midlatitude frontal systems ...
Triple-Frequency Radar Reflectivity Signatures of Snow: Observations and Comparisons with Theoretical Ice Particle Scattering Models
Publisher: American Meteorological Society
Abstract: n observation-based study is presented that utilizes aircraft data from the 2003 Wakasa Bay Advanced Microwave Scanning Radiometer Precipitation Validation Campaign to assess recent advances in the modeling of microwave ...
Uncertainties in Microwave Properties of Frozen Precipitation: Implications for Remote Sensing and Data Assimilation
Publisher: American Meteorological Society
Abstract: A combined active/passive modeling system that converts CloudSat observations to simulated microwave brightness temperatures (TB) is used to assess different ice particle models under precipitating conditions. Simulation ...

A Shallow Cumuliform Snowfall Census Using Spaceborne Radar
Publisher: American Meteorological Society
Abstract: he first observationally based near-global shallow cumuliform snowfall census is undertaken using multiyear CloudSat Cloud Profiling Radar observations. CloudSat snowfall observations and snowfall rate estimates from the ...
