RISFrequencies and Characteristics of Global Oceanic Precipitation from Shipboard Present-Weather Reports
Publisher: American Meteorological Society
Abstract: Ship reports of present weather obtained from the Comprehensive Ocean-Atmosphere Data Set are analyzed for the period 1958?91 in order to elucidate regional and seasonal variations in the climatological frequency, phase. ...
Physical and Microwave Radiative Properties of Precipitating Clouds. Part I: Principal Component Analysis of Observed Multichannel Microwave Radiances in Tropical Stratiform Rainfall
Publisher: American Meteorological Society
Abstract: Using stringent criteria pertaining to rain-cloud optical thickness and horizontal extent, 3203 multichannel microwave observations of heavy, widespread tropical precipitation over ocean were selected from 9 months of ...
Physical and Microwave Radiative Properties of Precipitating Clouds. Part II: A Parametric 1D Rain-Cloud Model for Use in Microwave Radiative Transfer Simulations
Publisher: American Meteorological Society
Abstract: A highly simplified, yet meteorologically realistic and flexible, parametric model is described for generating hydrometeor profiles and other environmental properties relevant to microwave radiative transfer calculations ...
Prevalence of Precipitation from Warm-Topped Clouds over Eastern Asia and the Western Pacific
Publisher: American Meteorological Society
Abstract: Land and ship surface synoptic reports of nondrizzle intensity precipitation in progress were matched with 3596 nearly coincident full disk 4-km resolution infrared images from the GMS-5 geostationary satellite, covering ...
Area-Average Solar Radiative Transfer in Three-Dimensionally Inhomogeneous Clouds: The Independently Scattering Cloudlet Model
Publisher: American Meteorological Society
Abstract: A new conceptual and computational basis is described for renormalizing the single-scatter and extinction properties (optical depth, single-scatter albedo, and scattering phase function or asymmetry parameter) of a ...
Prevalence of Precipitation from Warm-Topped Clouds over Eastern Asia and the Western Pacific
Publisher: American Meteorological Society
Abstract: Land and ship surface synoptic reports of nondrizzle intensity precipitation in progress were matched with 3596 nearly coincident full disk 4-km resolution infrared images from the GMS-5 geostationary satellite, covering ...
On Some Shortcomings of Shannon Entropy as a Measure of Information Content in Indirect Measurements of Continuous Variables
Publisher: American Meteorological Society
Abstract: AbstractShannon entropy has long been accepted as a primary basis for assessing the information content of sensor channels used for the remote sensing of atmospheric variables. It is not widely appreciated, however, that ...
Microwave Backscatter and Extinction by Soft Ice Spheres and Complex Snow Aggregates
Publisher: American Meteorological Society
Abstract: Coupled-dipole approximation (CDA) calculations of microwave extinction and radar backscatter are presented for nonhomogeneous (soft) ice spheres and for quasi-realistic aggregates of elementary ice crystal forms, including ...
Intercomparison of Bulk Microphysics Schemes in Model Simulations of Polar Lows
Publisher: American Meteorological Society
Abstract: Four spiraliform polar lows, two over the Sea of Japan and two over the Nordic Seas, were simulated with the Weather Research and Forecasting (WRF) model. Five mixed-phase bulk microphysics schemes (BMS) provided with WRF ...
The Sensitivity of Microwave Remote Sensing Observations of Precipitation to Ice Particle Size Distributions
Publisher: American Meteorological Society
Abstract: 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, ...
