RISA Probabilistic Multispectral Pattern Recognition Method for Detection of Overshooting Cloud Tops Using Passive Satellite Imager Observations
Publisher: American Meteorological Society
Abstract: eep convective updrafts often penetrate through the surrounding cirrus anvil and into the lower stratosphere. Cross-tropopause transport of ice, water vapor, and chemicals occurs within these ?overshooting tops? (OTs) along ...
Identifying the Uncertainty in Determining Satellite-Derived Atmospheric Motion Vector Height Attribution
Publisher: American Meteorological Society
Abstract: This study investigates the assignment of pressure heights to satellite-derived atmospheric motion vectors (AMVs), commonly known as cloud-drift and water vapor?motion winds. Large volumes of multispectral AMV datasets are ...
Application of Satellite-Derived Atmospheric Motion Vectors for Estimating Mesoscale Flows
Publisher: American Meteorological Society
Abstract: This study demonstrates methods to obtain high-density, satellite-derived atmospheric motion vectors (AMV) that contain both synoptic-scale and mesoscale flow components associated with and induced by cumuliform clouds ...
Forecasting Convective Initiation by Monitoring the Evolution of Moving Cumulus in Daytime GOES Imagery
Publisher: American Meteorological Society
Abstract: This study identifies the precursor signals of convective initiation within sequences of 1-km-resolution visible (VIS) and 4?8-km infrared (IR) imagery from the Geostationary Operational Environmental Satellite (GOES) ...
On the Development of Above-Anvil Cirrus Plumes in Extratropical Convection
Publisher: American Meteorological Society
Abstract: xpansive cirrus clouds present above the anvils of extratropical convection have been observed in satellite and aircraft-based imagery for several decades. Despite knowledge of their occurrence, the precise mechanisms and ...
A Method for Calculating the Height of Overshooting Convective Cloud Tops Using Satellite-Based IR Imager and CloudSat Cloud Profiling Radar Observations
Publisher: American Meteorological Society
Abstract: ssigning accurate heights to convective cloud tops that penetrate into the upper troposphere?lower stratosphere (UTLS) region using infrared (IR) satellite imagery has been an unresolved issue for the satellite research ...
Validation of Satellite-Based Objective Overshooting Cloud-Top Detection Methods Using CloudSat Cloud Profiling Radar Observations
Publisher: American Meteorological Society
Abstract: wo satellite infrared-based overshooting convective cloud-top (OT) detection methods have recently been described in the literature: 1) the 11-?m infrared window channel texture (IRW texture) method, which uses IRW channel ...
Comparisons of Satellite-Derived Atmospheric Motion Vectors, Rawinsondes, and NOAA Wind Profiler Observations
Publisher: American Meteorological Society
Abstract: Geostationary satellite-derived atmospheric motion vectors (AMVs) have been used over several decades in a wide variety of meteorological applications. The ever-increasing horizontal and vertical resolution of numerical ...
A Statistical Evaluation of GOES Cloud-Top Properties for Nowcasting Convective Initiation
Publisher: American Meteorological Society
Abstract: The goal of this project is to validate and extend a study by Mecikalski and Bedka that capitalized on information the Geostationary Operational Environmental Satellite (GOES) instruments provide for nowcasting (i.e., 0?1-h ...
Examining Deep Convective Cloud Evolution Using Total Lightning, WSR-88D, and GOES-14 Super Rapid Scan Datasets
Publisher: American Meteorological Society
Abstract: he Geostationary Operational Environmental Satellite-14 (GOES-14) Imager operated in 1-min Super Rapid Scan Operations for GOES-R (SRSOR) mode during summer and fall of 2012 to emulate the high temporal resolution sampling ...
