An h-Adaptive Finite-Element Technique for Constructing 3D Wind Fields
(American Meteorological Society, 2009)An h-adaptive, mass-consistent finite-element model (FEM) has been developed for constructing 3D wind fields over irregular terrain utilizing sparse meteorological tower data. The element size in the computational domain ... -
Development and Evaluation of a Coupled Photosynthesis-Based Gas Exchange Evapotranspiration Model (GEM) for Mesoscale Weather Forecasting Applications
(American Meteorological Society, 2009)Current land surface schemes used for mesoscale weather forecast models use the Jarvis-type stomatal resistance formulations for representing the vegetation transpiration processes. The Jarvis scheme, however, despite its ... -
A Two-Dimensional Solution of the Advection–Diffusion Equation with Dry Deposition to the Ground
(American Meteorological Society, 2008)A mathematical scheme is developed to simulate the vertical turbulent dispersion of air pollution that is absorbed or deposited to the ground. The scheme is an exact analytical solution of the atmospheric diffusion equation, ... -
A Nonstationary Extreme Value Analysis for the Assessment of Changes in Extreme Annual Wind Speed over the Gulf of St. Lawrence, Canada
(American Meteorological Society, 2008)Changes in the extreme annual wind speed in and around the Gulf of St. Lawrence (Canada) were investigated through a nonstationary extreme value analysis of the annual maximum 10-m wind speed obtained from the North American ... -
Deriving Atmospheric Temperature of the Tropopause Region–Upper Troposphere by Combining Information from GPS Radio Occultation Refractivity and High-Spectral-Resolution Infrared Radiance Measurements
(American Meteorological Society, 2008)Global positioning system radio occultation (GPS/RO) measurements from the Challenging Minisatellite Payload (CHAMP) and Satelite de Aplicaciones Cientificas-C (SAC-C) satellites are used to improve tropospheric profile ... -
An Empirical Analysis of Bulk Cn2 Models over Water
(American Meteorological Society, 2008)This article examines some of the difficulties associated with the determination of C2n over water in a coastal region using a bulk model. The analysis shows the need to supplement bulk models with elements that do not ... -
El Niño–Southern Oscillation Impacts on Rice Production in Luzon, the Philippines
(American Meteorological Society, 2009)This study uses regression analysis to evaluate the relationships among sea surface temperature anomalies (SSTA) averaged over the Niño-3.4 region (5°N?5°S, 120°?170°W), rainfall, and rice production, area harvested, and ... -
Polarimetric Signatures in Supercell Thunderstorms
(American Meteorological Society, 2008)Data from polarimetric radars offer remarkable insight into the microphysics of convective storms. Numerous tornadic and nontornadic supercell thunderstorms have been observed by the research polarimetric Weather Surveillance ... -
Estimating Spatial Variability in Atmospheric Properties over Remotely Sensed Land Surface Conditions
(American Meteorological Society, 2008)This paper investigates the spatial relationships between surface fluxes and near-surface atmospheric properties (AP), and the potential errors in flux estimation due to homogeneous atmospheric inputs over heterogeneous ... -
Use of Numerical Forecasts for Improving TMI Rain Retrievals over the Mountainous Area in Korea
(American Meteorological Society, 2008)Topographical influences on the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) rain retrievals over the terrain area of the Korean peninsula were examined using a training dataset constructed from numerical ... -
Measuring East Asian Summer Monsoon Rainfall Contributions by Different Weather Systems over Taiwan
(American Meteorological Society, 2008)The east Asian summer monsoon (EASM) is characterized by a distinct life cycle consisting of the active, break, and revival monsoon phases. Different weather systems prevail in each phase following the change of large-scale ... -
On the Role of Snow Cover in Depressing Air Temperature
(American Meteorological Society, 2008)This study empirically examines the role of snow depth on the depression of air temperature after controlling for effect of temperature changes above the boundary layer. In addition, this study examines the role of cloud ... -
Radar Measurement of Rainfall with and without Polarimetry
(American Meteorological Society, 2008)Raindrop size distributions (DSDs) for tropical convective storms are used to examine the relationships between the parameters of a gamma DSD, with special emphasis on their variation with the stage of the storm. Such a ... -
