RISThe Naval Research Laboratory’s Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS)
Publisher: American Meteorological Society
Abstract: The three-dimensional Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS) has been developed by the Naval Research Laboratory. COAMPS consists of an atmospheric data assimilation system comprising data quality ...
Operational Tropical Cyclone Model Results in the Pacific During 1979
Publisher: American Meteorological Society
Abstract: A statistical comparison is made between two versions of a tropical cyclone model tested on Pacific storms during 1979. One version of the model uses periodic boundary conditions on the cast and west and free-slip walls ...
Description and Evaluation of NORAPS: The Navy Operational Regional Atmospheric Prediction System
Publisher: American Meteorological Society
Abstract: A complete regional forecast system (NORAPS) has been developed for the Navy. The forecast grid is globally relocatable and can be set to any size and resolution. NORAPS performs wind and mass analyses, a static initialization, ...
Evaluation of a Regional Model with an Update Cycle
Publisher: American Meteorological Society
Abstract: Improvements have been made to the Navy Operational Regional Atmospheric Prediction System (NORAPS). A complete description of the latest version of NORAPS is presented. Also, tests have been performed to determine the ...
The Effect of the Physical Parameterizations and the Land Surface on Rainfall in Poland
Publisher: American Meteorological Society
Abstract: igh-resolution numerical experiments were conducted over two separate months to study the effect of different physical parameterizations and different representations of the land surface on the prediction of rainfall events ...
The Fleet Numerical Weather Central Tropical Cyclone Model: Comparison of Cyclic and One-Way Interactive Boundary Conditions
Publisher: American Meteorological Society
Abstract: One of the major problems in the development of limited-area models is the specification of reasonable boundary conditions. In this paper, the results of the use of one-way interactive boundary conditions in the Fleet ...
A vorticity Budget over the Marshall Islands During the Spring and Summer Months
Publisher: American Meteorological Society
Abstract: Objectively analyzed wind fields from the tropical western Pacific in the area of the ITCZ (Marshall Islands, April?July 1958) were used to evaluate average monthly values of the large-scale terms in the vorticity equation. ...
Effect of Two-Way Air–Sea Coupling in High and Low Wind Speed Regimes
Publisher: American Meteorological Society
Abstract: A recent advance in the Coupled Ocean?Atmosphere Mesoscale Prediction System (COAMPS) is described and used to study two-way air?sea coupling and its impact on two different weather scenarios. The first case examines the ...
Naval Research Laboratory Multiscale Targeting Guidance for T-PARC and TCS-08
Publisher: American Meteorological Society
Abstract: As part of The Observing System Research and Predictability Experiment (THORPEX) Pacific Asian Regional Campaign (T-PARC) and the Office of Naval Research?s (ONR?s) Tropical Cyclone Structure-08 (TCS-08) experiments, a ...
The Impact of Ice Phase Cloud Parameterizations on Tropical Cyclone Prediction
Publisher: American Meteorological Society
Abstract: he impact of ice phase cloud microphysical processes on prediction of tropical cyclone environment is examined for two microphysical parameterizations using the Coupled Ocean?Atmosphere Mesoscale Prediction System?Tropical ...
