RISParameterization of Generalized Cloud Overlap for Radiative Calculations in General Circulation Models
Publisher: American Meteorological Society
Abstract: New radiative parameterizations have been developed for the National Center for Atmospheric Research (NCAR) Community Atmospheric Model (CAM). The CAM is the next version of the NCAR Community Climate Model (CCM). This ...
The Operational Complex Quality Control of Radiosonde Heights and Temperatures at the National Centers for Environmental Prediction. Part I: Description of the Method
Publisher: American Meteorological Society
Abstract: The quality control of meteorological data has always been an important, if not always fully appreciated, step in the use of the data for analysis and forecasting. In most quality-control approaches, erroneous data are ...
The Operational Complex Quality Control of Radiosonde Heights and Temperatures at the National Centers for Environmental Prediction. Part II: Examples of Error Diagnosis and Correction from Operational Use
Publisher: American Meteorological Society
Abstract: The method of complex quality control of radiosonde heights and temperatures (CQCHT) has been under continuous development and improvement at the National Centers for Environmental Prediction since 1988. Part I of this ...
Effects of Enhanced Shortwave Absorption on Coupled Simulations of the Tropical Climate System
Publisher: American Meteorological Society
Abstract: The effects of enhanced shortwave absorption on coupled simulations of the tropical climate have been tested using the National Center for Atmospheric Research Climate System Model. The enhancement in cloudy-sky shortwave ...
A Comparison of Explicit and Semi-Implicit Model Calculations of Geostrophic Adjustment
Publisher: American Meteorological Society
Abstract: The adjustment properties of numerical models are important both from the Point of view of the handling of noise and the ability to produce proper quasi-geostrophic states from physically derived imbalances between mass ...
Complex Quality Control of Significant Level Rawinsonde Temperatures
Publisher: American Meteorological Society
Abstract: Rawinsonde heights and temperatures have been quality controlled using complex quality control at the National Centers for Atmospheric Prediction since December 1988 when an algorithm using only hydrostatic checking was ...
OPERATIONAL-EXPERIMENTAL NUMERICAL FORECASTING FOR THE TROPICS
Publisher: American Meteorological Society
Abstract: A primitive equation barotropic forecast model is employed independently at 700 mb. and 300 mb. to produce a wind forecast to 36 hr. once daily (from 1200 gmt real data analyses) for the entire tropical belt between 48°N. ...
First-Order Structure Function Analysis of Statistical Scale Invariance in the AIRS-Observed Water Vapor Field
Publisher: American Meteorological Society
Abstract: he power-law scale dependence, or scaling, of first-order structure functions of the tropospheric water vapor field between 58°S and 58°N is investigated using observations from the Atmospheric Infrared Sounder (AIRS). ...
Comprehensive Hydrostatic Quality Control at the National Meteorological Center
Publisher: American Meteorological Society
Abstract: The Comprehensive Hydrostatic Quality Control (CHQC) of rawinsonde data on height and temperature at mandatory isobaric surfaces designed and implemented at the National Meteorological Center in Washington is described in ...
Effects of Black Carbon Aerosols on the Indian Monsoon
Publisher: American Meteorological Society
Abstract: A six-member ensemble of twentieth-century simulations with changes to only time-evolving global distributions of black carbon aerosols in a global coupled climate model is analyzed to study the effects of black carbon ...
