RISCloud Predictions Diagnosed from Mesoscale Weather Model Forecasts
Publisher: American Meteorological Society
Abstract: Observed cloud characteristics, such as cloud cover, type, and base and top altitude, are of interest to the U.S. Air Force operational community for mission support. Predictions of such cloud characteristics are useful ...
Alternative Forms of Humidity Information in Global Data Assimilation
Publisher: American Meteorological Society
Abstract: Global data analysis procedures were developed to perform data assimilation for observed geopotential heights wind components, and relative humidity. These procedures were implemented in conjunction with a global spectral ...
Cloud Predictions Diagnosed from Global Weather Model Forecasts
Publisher: American Meteorological Society
Abstract: The U.S. Air Force has a long history of investment in cloud analysis and prediction operations. Their need for accurate cloud cover information has resulted in routine production of global cloud analyses (from their RTNEPH ...
Diagnosis and Correction of Systematic Humidity Error in a Global Numerical Weather Prediction Model
Publisher: American Meteorological Society
Abstract: Accuracy of humidity forecasts has been considered relatively unimportant to much of the operational numerical weather prediction (NWP) community. However, the U.S. Air Force is interested in accurate water vapor and cloud ...
Analysis and Prediction of Cirrus-Top Altitude and Ice Water Path in a Mesoscale Area
Publisher: American Meteorological Society
Abstract: Vertical distributions of clouds have been a focus of many studies, motivated by their importance in radiative transfer processes in climate models. This study examines the horizontal distribution of cirrus clouds by means ...
The Structure and Properties of African Wave Disturbances as Observed During Phase III of GATE
Publisher: American Meteorological Society
Abstract: A compositing method is used to determine the average structure and properties of eight wave disturbances observed over west Africa and the eastern Atlantic during the period 23 August-19 September, 1974, a period marked ...
The Energetics of African Wave Disturbances as observed During Phase III of GATE
Publisher: American Meteorological Society
Abstract: Fields of the meteorological variables in composite wave disturbance constructed for the region from IOOE to 31°W and 1°S to 26°N and for land and ocean subregions are used to diagnose energy transformations in African ...
A Characterization of Cirrus Cloud Properties That Affect Laser Propagation
Publisher: American Meteorological Society
Abstract: Future high-altitude laser systems may be affected by cirrus clouds. Laser transmission models were applied to measured and retrieved cirrus properties to determine cirrus impact on power incident on a target or receiver. ...
Assessment of the Impact of Simulated Satellite Lidar Wind and Retrieved 183 GHz Water Vapor Observations on a Global Data Assimilation System
Publisher: American Meteorological Society
Abstract: A series of observing system simulation experiments (0SSEs) was conducted to assess the impacts on the Air Force Geophysics Laboratory (GL) global data assimilation system (GDAS) of a satellite Doppler wind lidar sounding ...
