An Evaluation of Two Models for Estimation of the Roughness Height for Heat Transfer between the Land Surface and the Atmosphere
(American Meteorological Society, 2001)Roughness height for heat transfer is a crucial parameter in estimation of heat transfer between the land surface and the atmosphere. Although many empirical formulations have been proposed over the past few decades, the ... -
Geostatistical Analysis of Orographic Rainbands
(American Meteorological Society, 2001)Based on weather radar detection, orographic rainbands parallel to wind direction may persist for several hours over a Mediterranean mountainous region prone to stable wind and humidity conditions. A statistical analysis ... -
Snowdrift Sublimation in a Katabatic Wind Region of the Antarctic Ice Sheet
(American Meteorological Society, 2001)This paper presents snowdrift sublimation rates evaluated from meteorological and snowdrift data observed over Antarctic snow surfaces during austral summer. Snowdrift sublimation is found to be the major contributor to ... -
On the Computation of Gradients from Observations over Complex Terrain
(American Meteorological Society, 2001)A mathematical scheme is developed to compute the gradients of observations taken over complex terrain. The method is applied to an artificial example to demonstrate the scheme. An application is made to surface pressure ... -
First- and Second-Order Closure Models for Wind in a Plant Canopy
(American Meteorological Society, 2001)Katul and Chang recently compared the performance of two second-order closure models with observations of wind and turbulence in the Duke Forest canopy, noting that such models ?alleviate some of the theoretical objections ... -
Fluid Modeling and the Evaluation of Inherent Uncertainty
(American Meteorological Society, 2001)Atmospheric dispersion models are widely used to estimate the impact of nonreactive pollutant releases into the atmosphere. Most such models predict the ensemble-average concentration field, the average over a large ... -
Solar Radiation Mapping from NOAA AVHRR Data in Catalonia, Spain
(American Meteorological Society, 2001)A statistical model is presented for the determination of hourly global solar radiation from the National Oceanic and Atmospheric Administration advanced very high resolution radiometer (NOAA AVHRR) satellite data, which ... -
The Evolution of the Goddard Profiling Algorithm (GPROF) for Rainfall Estimation from Passive Microwave Sensors
(American Meteorological Society, 2001)This paper describes the latest improvements applied to the Goddard profiling algorithm (GPROF), particularly as they apply to the Tropical Rainfall Measuring Mission (TRMM). Most of these improvements, however, are ... -
Contribution of Tropical Cyclones to the North Atlantic Climatological Rainfall as Observed from Satellites
(American Meteorological Society, 2001)The tropical cyclone rainfall climatological study performed for the North Pacific was extended to the North Atlantic. Similar to the North Pacific tropical cyclone study, mean monthly rainfall within 444 km of the center ... -
A Satellite Method to Identify Structural Properties of Mesoscale Convective Systems Based on the Maximum Spatial Correlation Tracking Technique (MASCOTTE)
(American Meteorological Society, 2001)A simple, fully automated, and efficient method to determine the structural properties and evolution (tracking) of cloud shields of convective systems (CS) is described. The method, which is based on the maximum spatial ... -
A Synoptic Weather Pattern and Sounding-Based Climatology of Freezing Precipitation in the United States East of the Rocky Mountains
(American Meteorological Society, 2001)An analysis of 411 winter storms that produced freezing precipitation events in the United States east of the Rocky Mountains over the 25-yr period of 1970?94 is presented to identify specific weather patterns associated ... -
Cloud Type and Macrophysical Property Retrieval Using Multiple Remote Sensors
(American Meteorological Society, 2001)A cloud detection algorithm based on ground-based remote sensors has been developed that can differentiate among various atmospheric targets such as ice and water clouds, virga, precipitation, and aerosol layers. Standard ... -
Computational Modeling of the Turbulent Penetrative Convection above the Urban Heat Island in a Stably Stratified Environment
(American Meteorological Society, 2001)A three-equation model of the turbulent transport of momentum and heat for simulating a circulation structure over the heat island in a stably stratified environment under nearly calm conditions is formulated. The turbulent ... -
A Comparison between Polarimetric Radar and Wind Profiler Observations of Precipitation in Tropical Showers
(American Meteorological Society, 2001)This paper describes the results of an experiment that combines the data from a 5-cm-wavelength polarimetric radar and multiple-frequency wind profilers to examine the polarimetric signatures associated with the microphysical ... -
Comparison of Planetary Boundary Layer Model Winds with Dropsonde Observations in Tropical Cyclones
