Thermal and Geometric Controls on the Rate of Surface Air Temperature Changes in a Medium-Sized, Midlatitude City
(American Meteorological Society, 2007)Gradual cooling in the evening forms a wintertime nocturnal urban heat island. This work, with a mesoscale model involving urban canopy physics, is an examination of how four thermal and geometric controls?anthropogenic ... -
Daily Microwave-Derived Surface Temperature over Canada/Alaska
(American Meteorological Society, 2007)The land surface temperature variation over northern high latitudes in response to the increase in greenhouse gases is challenging because of the lack of meteorological stations. A new method to derive the surface temperature ... -
Fine Structure of Vertical Motion in the Stratiform Precipitation Region Observed by a VHF Doppler Radar Installed in Sumatra, Indonesia
(American Meteorological Society, 2007)Vertical motion W profiles in the stratiform precipitation region of mesoscale cloud clusters were investigated using wind data observed by VHF Doppler radar installed in western Sumatra Island (0.2°S, 100.32°E). A special ... -
New Categorical Metrics for Air Quality Model Evaluation
(American Meteorological Society, 2007)Traditional categorical metrics used in model evaluations are ?clear cut? measures in that the model?s ability to predict an ?exceedance? is defined by a fixed threshold concentration and the metrics are defined by ... -
On the Evaporation Duct for Inhomogeneous Conditions in Coastal Regions
(American Meteorological Society, 2007)Evaporation ducts are ubiquitous phenomena over the oceans, and they are responsible for much of the over-the-horizon propagation occurring with millimeter and microwave radars. The height of the evaporation duct depends ... -
Model-Generated Predictions of Dry Thunderstorm Potential
(American Meteorological Society, 2007)Dry thunderstorms (those that occur without significant rainfall at the ground) are common in the interior western United States. Moisture drawn into the area from the Gulfs of Mexico and California is sufficient to form ... -
Scattering of Ice Particles at Microwave Frequencies: A Physically Based Parameterization
(American Meteorological Society, 2007)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 ... -
Possible Misidentification of Rain Type by TRMM PR over Tibetan Plateau
(American Meteorological Society, 2007)Rain-type statistics derived from Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) standard product show that some 70% of raining pixels in the central Tibetan Plateau summer are stratiform?a clear ... -
Intercomparison of Single-Column Numerical Models for the Prediction of Radiation Fog
(American Meteorological Society, 2007)The short-term forecasting of fog is a difficult issue that can have a large societal impact. Radiation fog appears in the surface boundary layer, and its evolution is driven by the interactions between the surface and ... -
Comparison of Efficient Explicit Schemes for Shallow-Water Equations—Characteristics-Based Fractional-Step Method and Multimoment Eulerian Scheme
(American Meteorological Society, 2007)Two explicit schemes for the numerical solution of the shallow-water equations are examined. The directional-splitting fractional-step method permits relatively large time steps without an iterative process by using a ... -
Urban Modification in a Mesoscale Model and the Effects on the Local Circulation in the Pearl River Delta Region
(American Meteorological Society, 2007)The Pearl River Delta (PRD) region, located in the southern part of Guangdong Province in China, is one of the most rapidly developing regions in the world. The evolution of local and regional sea-breeze circulation (SBC) ... -
Uses of NOAA-16 and -18 Satellite Measurements for Verifying the Limb-Correction Algorithm
(American Meteorological Society, 2007)The Advanced Microwave Sounding Unit (AMSU) images display strong dependence on the scanning angle because of the temperature gradient of the atmosphere and the change in the optical pathlength between Earth and the ... -
An Empirical Orthogonal Function Iteration Approach for Obtaining Homogeneous Radiative Fluxes from Satellite Observations
(American Meteorological Society, 2007)Conventional observations of climate parameters are sparse in space and/or time, and the representativeness of such information needs to be optimized. Observations from satellites provide improved spatial coverage over ... -

Daily NDVI Relationship to Cloud Cover
(American Meteorological Society, 2007)A normalized difference vegetation index (NDVI) cloud index (NCI) was derived from Pathfinder Advanced Very High Resolution Radiometer (AVHRR) daily NDVI data and compared with observed cloud amounts and a sunshine ... -
Bulk Scattering Properties for the Remote Sensing of Ice Clouds. Part III: High-Resolution Spectral Models from 100 to 3250 cm−1
(American Meteorological Society, 2007)This study reports on the development of bulk single-scattering models for ice clouds that are appropriate for use in hyperspectral radiative transfer cloud modeling over the spectral range from 100 to 3250 cm?1. The models ... -
Parameterization of Convective Transport in a Lagrangian Particle Dispersion Model and Its Evaluation
(American Meteorological Society, 2007)This paper presents the revision and evaluation of the interface between the convective parameterization by Emanuel and ?ivkovi?-Rothman and the Lagrangian particle dispersion model ?FLEXPART? based on meteorological data ... -

The Shear Layer above and in Urban Canopies
(American Meteorological Society, 2007)The nature and role of the shear layer, which occurs at the level of the average building height in urban canopies, are poorly understood. Velocity data are analyzed to determine the characteristics of the shear layer of ... -
Significant Inversions and Rapid In Situ Cooling at a Well-Sited Oklahoma Mesonet Station
(American Meteorological Society, 2007)The El Reno Oklahoma Mesonet (ELRE) site is one of a few Oklahoma Mesonet sites that has measured inversions of 10°C or greater between 1.5 and 9 m. Historical analyses revealed that strong inversions at ELRE have occurred ...
