Tropopause-Penetrating Convection from Three-Dimensional Gridded NEXRAD Data
Publisher: American Meteorological Society
Abstract: new method that combines radar reflectivities from individual Next Generation Weather Radars (NEXRAD) into a three-dimensional composite with high horizontal and vertical resolution is used to estimate storm-top altitudes ...
Comparison of Freezing-Level Altitudes from the NCEP Reanalysis with TRMM Precipitation Radar Brightband Data
Publisher: American Meteorological Society
Abstract: A global climatology of the altitude of the freezing level (0°C isotherm) is computed using 20 yr of 6-hourly output from the National Centers for Environmental Prediction (NCEP) reanalysis system. Mean statistics discussed ...
A Summary of Reflectivity Profiles from the First Year of TRMM Radar Data
Publisher: American Meteorological Society
Abstract: A preliminary climatology of reflectivity profiles derived from the first spaceborne precipitation radar (PR), which is on board the Tropical Rainfall Measuring Mission (TRMM) satellite, is described using the data from ...
A Comparison of Tropical Precipitation Simulated by the Community Climate Model with That Measured by the Tropical Rainfall Measuring Mission Satellite
Publisher: American Meteorological Society
Abstract: This study evaluates the simulation of tropical precipitation by the Community Climate Model, version 3, (CCM3) developed at the National Center for Atmospheric Research. Monthly mean precipitation rates from an ensemble ...
Equatorial Waves Including the Madden–Julian Oscillation in TRMM Rainfall and OLR Data
Publisher: American Meteorological Society
Abstract: Four years of outgoing longwave radiation (OLR) and rainfall data from the Tropical Rainfall Measuring Mission (TRMM) are investigated to find the dominant large-scale wave modes in the Tropics. By using space? time ...
A Comparison of Gamma and Lognormal Distributions for Characterizing Satellite Rain Rates from the Tropical Rainfall Measuring Mission
Publisher: American Meteorological Society
Abstract: This study investigates the spatial characteristics of nonzero rain rates to develop a probability density function (PDF) model of precipitation using rainfall data from the Tropical Rainfall Measuring Mission (TRMM) ...
Error Reduction and Convergence in Climate Prediction
Publisher: American Meteorological Society
Abstract: Although climate models have steadily improved their ability to reproduce the observed climate, over the years there has been little change to the wide range of sensitivities exhibited by different models to a doubling of ...
A Networked Desktop Synoptic Laboratory
Publisher: American Meteorological Society
Abstract: Over the past several years, the Department of Atmospheric Sciences at the University of Illinois has developed a computerized weather laboratory that permits interactive access to real-time data from observing sites around ...
Input Data Requirements for Lagrangian Trajectory Models
Publisher: American Meteorological Society
Abstract: r 2011 an American Geophysical Union Chapman Conference was held in Grindelwald, Switzerland, titled ?Advances in Lagrangian Modeling of the Atmosphere.? Lagrangian models are being applied to a wide range of high-impact ...
Statistical Tests of Taylor’s Hypothesis: An Application to Precipitation Fields
Publisher: American Meteorological Society
Abstract: The Taylor hypothesis (TH) as applied to rainfall is a proposition about the space?time covariance structure of the rainfall field. Specifically, it supposes that if a spatiotemporal precipitation field with a stationary ...
