On Improving 4-km Mesoscale Model Simulations
Mar 01, 2006; ... ABSTRACT A previous study showed that use of analysis-nudging four-dimensional data assimilation (FDDA) and improved physics in the fifth-generation Pennsylvania State University-National Center for Atmospheric Research Mesoscale Model (MM5) produced the best overall performance on a ...
Correcting Active Scatterometer Data for the Effects of Rain Using Passive Radiometer Data
Mar 01, 2006; ... ABSTRACT A model for the effects of rain on scatterometer data is proposed. Data from the Advanced Microwave Scanning Radiometer (AMSR) and the SeaWinds scatterometer, both on the Midori-II satellite, are used. The model includes three basic rain effects: attenuation, rain roughening of ...
Tropical Cyclone Wind Retrievals from the Advanced Microwave Sounding Unit: Application to Surface Wind Analysis
Mar 01, 2006; ... ABSTRACT Horizontal winds at 850 hPa from tropical cyclones retrieved using the nonlinear balance equation, where the mass field was determined from Advanced Microwave Sounding Unit (AMSU) temperature soundings, are compared with the surface wind fields derived from NASA's Quick ...
Bayesian Estimation of Precipitation from Satellite Passive Microwave Observations Using Combined Radar-Radiometer Retrievals
Mar 01, 2006; ... ABSTRACT Precipitation estimation from satellite passive microwave radiometer observations is a problem that does not have a unique solution that is insensitive to errors in the input data. Traditionally, to make this problem well posed, a priori information derived from physical models ...
Rainfall Climate Regimes: The Relationship of Regional TRMM Rainfall Biases to the Environment
Mar 01, 2006; ... ABSTRACT Intercomparisons of satellite rainfall products have historically focused on the issue of global mean biases. Regional and temporal variations in these biases, however, are equally important for many climate applications. This has led to a critical examination of rainfall ...
Rain Retrieval from TMI Brightness Temperature Measurements Using a TRMM PR-Based Database
Mar 01, 2006; ... ABSTRACT This study focuses on improving the retrieval of rain from measured microwave brightness temperatures and the capability of the retrieved field to represent the mesoscale structure of a small intense hurricane. For this study, a database is constructed from collocated Tropical ...
Validation of a Receptor-Dispersion Model Coupled with a Genetic Algorithm Using Synthetic Data
Mar 01, 2006; ... ABSTRACT A methodology for characterizing emission sources is presented that couples a dispersion and transport model with a pollution receptor model. This coupling allows the use of the backward (receptor) model to calibrate the forward (dispersion) model, potentially across a wide ...
On the Decay of Tropical Cyclone Winds Crossing Narrow Landmasses
Mar 01, 2006; ... ABSTRACT A method is developed to adjust the Kaplan and DeMaria tropical cyclone inland wind decay model for storms that move over narrow landmasses. The basic assumption that the wind speed decay rate after landfall is proportional to the wind speed is modified to include a factor equal ...
A Coupled Model to Simulate Snow Behavior on Roads
Mar 01, 2006; ... ABSTRACT To develop a decision-making tool for road management in winter, a numerical model resulting from the coupling of a soil model and a snow model was developed and validated using experimental results from a comprehensive experimental field campaign during three winters (1997/98, ...
Bridge Frost Prediction by Heat and Mass Transfer Methods
Mar 01, 2006; ... ABSTRACT Frost on roadways and bridges can present hazardous conditions to motorists, particularly when it occurs in patches or on bridges when adjacent roadways are clear of frost. To minimize materials costs, vehicle corrosion, and negative environmental impacts, frost-suppression ...
