The Development of Midlatitude Cirrus Models for MODIS Using FIRE-I, FIRE-II, and ARM In Situ Data
(American Meteorological Society, 2002)Detailed in situ data from cirrus clouds have been collected during dedicated field campaigns, but the use of the size and habit distribution data has been lagging in the development of more realistic cirrus scattering ... -
An Estimation-Based Precipitation Retrieval Algorithm for Attenuating Radars
(American Meteorological Society, 2002)A new method for retrieving rainfall profiles from a spaceborne radar is introduced. As a result of the frequencies necessary in spaceborne radar applications, attenuation by both rainfall and liquid cloud particles is ... -
UHF Radar Detection and Numerical Simulation of an Episode of Foehn and Lee Waves over the Northern Coast of Iberia
(American Meteorological Society, 2002)This work shows an episode of foehn- and lee-wave activity over the sea-facing slopes of the Cantabrian Mountain Range, on the northern coast of Iberia, as detected by a wind profiler radar (WPR?LAP 3000 at 1290 MHz) at ... -
A Regularized Neural Net Approach for Retrieval of Atmospheric and Surface Temperatures with the IASI Instrument
(American Meteorological Society, 2002)In this paper, a fast atmospheric and surface temperature retrieval algorithm is developed for the high-resolution Infrared Atmospheric Sounding Interferometer (IASI) spaceborne instrument. This algorithm is constructed ... -
Aircraft Icing Conditions in Northeast Colorado
(American Meteorological Society, 2002)The in-flight icing environment in northeastern Colorado is described through remote and in situ measurements. Four field efforts in the winters of 1990 through 1994 were conducted in the area, and comprehensive datasets ... -
Validation and Sensitivity Analysis of a New Atmosphere–Soil–Vegetation Model
(American Meteorological Society, 2002)This paper describes details, validation, and sensitivity analysis of a new atmosphere?soil?vegetation model. The model consists of one-dimensional multilayer submodels for atmosphere, soil, and vegetation and radiation ... -
A Gradient Wind Correction for Surface Pressure Fields Retrieved from Scatterometer Winds
(American Meteorological Society, 2002)Given a field of geostrophic winds and at least one pressure observation, a pressure field can be computed. If the winds are in reality gradient winds, then a correction must be applied to calculate the actual geostrophic ... -
On the Separation of Tropical Convective and Stratiform Rains
(American Meteorological Society, 2002)This work resolves an apparent conflict between the results of Yuter and Houze and Atlas et al. concerning relations between radar reflectivity factor Z and rainfall rate R derived from essentially the same drop size data ... -
Analytical Land–Atmosphere Radiometer Model
(American Meteorological Society, 2002)Conversion of radiometric land surface temperature (?r) to an equivalent isothermal (aerodynamic) surface temperature (?i) is important in balancing the land surface energy budget with satellite-based ?r measurements. An ... -
Microphysical Observations of Tropical Clouds
(American Meteorological Society, 2002)The results from airborne in situ sampling of convective tropical storms in the Amazon and Kwajalein are presented. Three cases from the Amazon and two from Kwajalein are compared and provide examples of the much larger ... -
Evaluating the Quality of Ground-Based Microwave Radiometer Measurements and Retrievals Using Detrended Fluctuation and Spectral Analysis Methods
(American Meteorological Society, 2002)Time series both of microwave radiometer brightness temperature measurements at 23.8 and 31.4 GHz and of retrievals of water vapor and liquid water path from these brightness temperatures are evaluated using the detrended ... -
When is Rain Steady?
(American Meteorological Society, 2002)By definition, steady rain should have a nearly constant rainfall rate. Thus far, however, the criteria for determining when rain is steady remain qualitative and arbitrary. The authors suggest a definition for steadiness ... -
Economic Impacts of Climate Variability in South Africa and Development of Resource Prediction Models
(American Meteorological Society, 2002)An analysis of food and water supplies and economic growth in South Africa leads to the realization that climate variability plays a major role. Summer rainfall in the period of 1980?99 is closely associated (variance = ... -
Distribution of Rainfall Parameters near the Coasts of France and Senegal
(American Meteorological Society, 2002)Because of a lack of data, the structural characteristics of rain fields over the sea are poorly documented. Coastal radars offer an opportunity to observe the distribution of rain parameters at the land?sea transition. ... -
Local Circulations Developed in the Vicinity of Both Coastal and Inland Urban Areas: A Numerical Study with a Mesoscale Atmospheric Model
(American Meteorological Society, 2002)A numerical study was conducted of the effects of two nearby urban areas, one coastal and one inland, on the local circulations and transport of urban pollutants, using a 3D mesoscale incompressible and hydrostatic atmospheric ... -
Observations of the Afternoon Transition of the Convective Boundary Layer
(American Meteorological Society, 2002)This manuscript uses 915-MHz wind profiler reflectivity and Doppler spectral width data in time versus altitude to characterize general behaviors of the ending of the daytime convective boundary layer. From a wide variety ... -
Evaluation of a Data Assimilation Technique for a Mesoscale Meteorological Model Used for Air Quality Modeling
(American Meteorological Society, 2002)An observational data assimilation (ODA) technique was evaluated based on both its direct effect on meteorological model fields and its indirect effect on the results of two air quality models that input these meteorological ... -
A Comparison of Cloud and Rainfall Information from Instantaneous Visible and Infrared Scanner and Precipitation Radar Observations over a Frontal Zone in East Asia during June 1998
(American Meteorological Society, 2000)The comparison between cloud information and rainfall is studied using infrared and radar data from the Tropical Rainfall Measuring Mission. Cloud information from the visible and infrared scanner was compared with rain ... -
