Variability of Graupel and Snow Observed in Tropical Oceanic Convection by Aircraft during TRMM KWAJEX
(American Meteorological Society, 2009)Empirical characterization of graupel and snow in precipitating tropical convective clouds is important for refining satellite precipitation retrieval algorithms and cloud-resolving and radiative transfer models. Microphysics ... -
Precipitation Characteristics of Trade Wind Clouds during RICO Derived from Radar, Satellite, and Aircraft Measurements
(American Meteorological Society, 2009)Precipitation characteristics of trade wind clouds over the Atlantic Ocean near Barbuda are derived from radar and aircraft data and are compared with satellite-observed cloud fields collected during the Rain in Cumulus ... -
Cirrus Microphysical Properties and Air Motion Statistics Using Cloud Radar Doppler Moments. Part II: Climatology
(American Meteorological Society, 2008)The algorithm described in Part I has been applied to the millimeter cloud radar observations from January 1999 to December 2005 at the Atmospheric Radiation Measurement Program (ARM) Southern Great Plains (SGP) and Tropical ... -
A New Value of the von Kármán Constant: Implications and Implementation
(American Meteorological Society, 2009)The von Kármán constant k occurs throughout the mathematics that describe the atmospheric boundary layer. In particular, because k was originally included in the definition of the Obukhov length, its value has both explicit ... -
Characteristics of Rain Integral Parameters during Tropical Convective, Transition, and Stratiform Rain at Gadanki and Its Application in Rain Retrieval
(American Meteorological Society, 2009)In the present study the characteristics of rain integral parameters during tropical convective (C), transition (T), and stratiform (S) types of rain are studied with the help of Joss?Waldvogel disdrometer (JWD), L-band, ... -
Freezing Drizzle Detection with WSR-88D Radars
(American Meteorological Society, 2009)This study describes a freezing drizzle detection algorithm based on the Weather Surveillance Radar-1988 Doppler (WSR-88D) measured radar reflectivity. Although radar returns from freezing drizzle and light snow are ... -
High-Resolution Large-Eddy Simulations of Scalar Transport in Atmospheric Boundary Layer Flow over Complex Terrain
(American Meteorological Society, 2008)This paper presents high-resolution numerical simulations of the atmospheric flow and concentration fields accompanying scalar transport and diffusion from a point source in complex terrain. Scalar dispersion is affected ... -
A Modified Tracer Selection and Tracking Procedure to Derive Winds Using Water Vapor Imagers
(American Meteorological Society, 2008)The remotely sensed upper-tropospheric water vapor wind information has been of increasing interest for operational meteorology. A new tracer selection based on a local image anomaly and tracking procedure, itself based ... -
Comparison of the Diurnal Cycle of Outgoing Longwave Radiation from a Climate Model with Results from ERBE
(American Meteorological Society, 2008)The diurnal cycle of outgoing longwave radiation (OLR) computed by a climate model provides a powerful test of the numerical description of various physical processes. Diurnal cycles of OLR computed by version 3 of the ... -
Empirical Modeling of Layered Integrated Water Vapor Using Surface Mixing Ratio in Nigeria
(American Meteorological Society, 2009)Using the available upper-air data for three stations in Nigeria (Lagos, a coastal station; Minna, an inland station; and Kano, a sub-Sahelian station), an intensive examination has been carried out on the linkage between ... -
Drop Size Distributions and the Lack of Small Drops in RICO Rain Shafts
(American Meteorological Society, 2009)Data from the new two-dimensional stereo (2D-S) probe are used to evaluate drop size distributions in rain shafts observed during the Rain in Shallow Cumulus over the Ocean (RICO) experiment. The 2D-S takes images of both ... -
L-Moment Estimators as Applied to Gamma Drop Size Distributions
(American Meteorological Society, 2008)The traditional approach with experimental raindrop size data has been to use the method of moments in the fitting procedure to estimate the parameters for the raindrop size distribution function. However, the moment method ... -
Lake-Effect Thunderstorms in the Lower Great Lakes
(American Meteorological Society, 2009)Cloud-to-ground (CG) lightning, radar, and radiosonde data were examined to determine how frequently lake-effect storms (rain/snow) with lightning occurred over and near the lower Great Lakes region (Lakes Erie and Ontario) ... -
Deriving the Surface Soil Heat Flux from Observed Soil Temperature and Soil Heat Flux Profiles Using a Variational Data Assimilation Approach
(American Meteorological Society, 2009)A novel approach to infer surface soil heat fluxes from measured profiles of soil temperature, soil heat flux, and observations of the vegetation canopy temperature and the incoming shortwave radiation is evaluated for the ... -
Climatology of Lake-Effect Precipitation Events over Lake Champlain
