(American Meteorological Society, 2001)In this study, an automatic algorithm for monitoring areas of cold cloud tops within mesoscale convective systems that produced floods in Greece is developed. The technique is based on Meteosat infrared and water vapor ... -
Approximation and Inversion of a Complex Meteorological System via Local Linear Filters
(American Meteorological Society, 2001)Dynamical models involving systems of numerous differential equations are commonly used to describe meteorological behavior. Approximations to such systems are often desired, particularly for inversion problems when the ... -
Lake Michigan Lake Breezes: Climatology, Local Forcing, and Synoptic Environment
(American Meteorological Society, 2001)A method was developed to identify the occurrence of lake-breeze events along the eastern, western, and both shores of Lake Michigan during a 15-yr period (1982?96). Comparison with detailed observations from May through ... -
Variational Retrieval of Cloud Parameters from GOES Sounder Longwave Cloudy Radiance Measurements
(American Meteorological Society, 2001)The optimal nonlinear inversion or one-dimensional variational (1DVAR) method was used to retrieve the cloud-top height and effective cloud amount from Geostationary Operational Environmental Satellite (GOES) sounder ... -
REMO Cloud Modeling: Improvements and Validation with ISCCP DX Data
(American Meteorological Society, 2001)The grid-scale cloud properties of the Regional-Scale Model (REMO) are compared with the cloud retrievals derived from the International Satellite Cloud Climatology Project (ISCCP) ?DX? datasets for the Baltic Sea Experiment ... -
Diurnal Variation of Summer Rainfall over Taiwan and Its Detection Using TRMM Observations
(American Meteorological Society, 2001)A surface-based rainfall monitoring network reveals that summer rainfall over Taiwan exhibits a prominent diurnal variation. In this study, an attempt has been made to detect the diurnal variability of Taiwan rainfall using ... -
The Sensitivity of Microwave Remote Sensing Observations of Precipitation to Ice Particle Size Distributions
(American Meteorological Society, 2001)This study investigates the effect of variable size distribution and density of precipitation ice particles on microwave brightness temperatures. For this purpose, a set of self-consistent relationships among rain rate, ... -
A Case Study of the Simultaneous Development of Multiple Lake-Breeze Fronts with a Boundary Layer Forecast Model
(American Meteorological Society, 2001)A fast-response boundary layer forecast mesoscale model has been used to simulate and to study the complex three-dimensional circulation associated with lake breezes in southwestern Ontario. The simultaneous development ... -
Application of Principal Component Analysis to High-Resolution Infrared Measurement Compression and Retrieval
(American Meteorological Society, 2001)A simulation study is used to demonstrate the application of principal component analysis to both the compression of, and meteorological parameter retrieval from, high-resolution infrared spectra. The study discusses the ... -
Simulation of Three-Dimensional Turbulent Velocity Fields
(American Meteorological Society, 2001)New algorithms for the simulation of three-dimensional homogeneous turbulent velocity fields are compared with standard spectral domain algorithms. Results are presented for a von Kármán model of the covariance tensor. For ... -
Statistical Contrail Forecasting
(American Meteorological Society, 2001)The current operational Air Force Weather Agency condensation trail (contrail) forecast technique is based on the Appleman algorithm, developed in the 1950s, with minor modifications. The Appleman algorithm requires accurate ... -
A New Method to Estimate Diffusion in Stable, Low-Wind Conditions
(American Meteorological Society, 2001)Sonic anemometer observations were made 10 m above ground level for a period of 1 yr. From these data, Eulerian autocorrelation functions were computed for the horizontal and vertical wind velocity fluctuations for low ... -
Multifractal Analysis of Line-Source Plume Concentration Fluctuations in Surface-Layer Flows
(American Meteorological Society, 2001)A codimension multifractal methodology was used to analyze and to model scalar concentration fluctuations within sulfur hexafluoride tracer gas plumes from a line source in atmospheric surface-layer flows. Correspondence ... -
