Retrieving the Root-Zone Soil Moisture from Surface Soil Moisture or Temperature Estimates: A Feasibility Study Based on Field Measurements
(American Meteorological Society, 1998)The bulk soil water content must be estimated accurately for short- and medium-term meteorological modeling. A method is proposed to retrieve the total soil moisture content as well as the field capacity from observed ... -
Remote Sensing of Ice Water Characteristics in Tropical Clouds Using Aircraft Microwave Measurements
(American Meteorological Society, 1998)An ice water path retrieval algorithm, using airborne Millimeter-Wave Imaging Radiometer brightness temperatures at 89, 150, and 220 GHz, is developed for tropical clouds. This algorithm is based on the results of radiative ... -
Modeling of Submillimeter Passive Remote Sensing of Cirrus Clouds
(American Meteorological Society, 1998)The scattering properties of cirrus clouds at submillimeter-wave frequencies are analyzed and characterized in this paper. This study lays a theoretical foundation for using radiometric measurements to investigate and ... -
Assessment of the Effects of Drop Size Distribution Variations Retrieved from UHF Radar on Passive Microwave Remote Sensing of Precipitation
(American Meteorological Society, 1998)Vertical profiles of drop size distribution (DSD) parameters are produced from data collected with the National Oceanographic and Atmospheric Administration 915- and 50-MHz Doppler radars at Darwin, Australia, for the ... -
Evaluation of an AVHRR Cloud Detection and Classification Method over the Central Arctic Ocean
(American Meteorological Society, 1998)A cloud classification method that uses both multispectral and textural features with a maximum likelihood discriminator is applied to full-resolution AVHRR (Advanced Very High Resolution Radiometer) data from 100 NOAA ... -
Observations and Numerical Simulations of Winds within a Broad Forested Valley
(American Meteorological Society, 1998)The Tennessee River Valley in the eastern part of Tennessee is a broad valley with a moist climate and extensive forest cover. A series of 50?100-m-high parallel ridges forms corrugations along the floor of the valley. ... -
A Statistical Modeling Approach to Passive Microwave Rainfall Retrieval
(American Meteorological Society, 1998)A new empirical algorithm for retrieving rainfall rates from passive microwave (particularly Special Sensor Microwave/Imager) data is presented. Errors caused by spatial and temporal variation of surface temperature, ... -
Physical Mechanism for the Tallahassee, Florida, Minimum Temperature Anomaly
(American Meteorological Society, 1998)Nighttime minimum temperatures at the Tallahassee Regional Airport (TLH) are colder in comparison with surrounding locations and other parts of the city, especially during the cool season (TLH minimum temperature anomaly). ... -
The Coupling of Vertical Velocity and Signal Power Observed with the SOUSY VHF Radar
(American Meteorological Society, 1998)The perturbations to the static stability (and hence to the radar reflectivity) and to the velocity in a vertically propagating gravity wave are correlated, and the sign of the correlation depends on whether the wave is ... -
Polarimetric Method for Ice Water Content Determination
(American Meteorological Society, 1998)Two variants of a polarimetric method to determine ice water content are presented. One uses specific differential phase and differential reflectivity and the other uses specific differential phase; both quantities are for ... -
Meteorological Processes Relevant to Forest Fire Dynamics on the Spanish Mediterranean Coast
(American Meteorological Society, 1998)The Valencian region on the Spanish east coast has experienced a significant increase in wildfires in the last 20 years, as have other areas in the Mediterranean basin. Experimental data and modeling results, obtained ... -
Dynamic Characteristics of Regional Flows around the Pyrénées in View of the PYREX Experiment. Part II: Solution of a Linear Model Compared to Field Measurements
(American Meteorological Society, 1998)This paper considers a linear hydrostatic model of a stable, uniform, constant rotational airflow over three- dimensional, elliptic, cross-sectional families of mountains in a z system. The surface pressure and the winds ... -
Bayesian Probability and Scalar Performance Measures in Gaussian Models
(American Meteorological Society, 1998)The transformation of a real, continuous variable into an event probability is reviewed from the Bayesian point of view, after which a Gaussian model is employed to derive an explicit expression for the probability. In ... -
Calculations of Aircraft Contrail Formation Critical Temperatures
(American Meteorological Society, 1997)Forecasts of condensation trail (contrail) formation are an extremely important consideration in military aircraft operations, particularly in the operation of stealth aircraft. Some recently published works have claimed ... -
