Tropical Cyclone Track Forecasts Using an Ensemble of Dynamical Models
Publisher: American Meteorological Society
Abstract: The relative independence of the tropical cyclone track forecasts produced by regional and global numerical weather prediction models suggests that a simple ensemble average or consensus forecast derived from a combination ...
Impact of Satellite Observations on the Tropical Cyclone Track Forecasts of the Navy Operational Global Atmospheric Prediction System
Publisher: American Meteorological Society
Abstract: The tropical cyclone (TC) track forecasts of the Navy Operational Global Atmospheric Prediction System (NOGAPS) were evaluated for a number of data assimilation experiments conducted using observational data from two ...
An Improved Method for Determining Measurement System Noise Spectra
Publisher: American Meteorological Society
Abstract: A simultaneous equations solution technique is developed to estimate the noise variance density spectra of three or more independent measurement systems observing the same input. Using dew-point data collected during a ...
Prediction of Consensus Tropical Cyclone Track Forecast Error
Publisher: American Meteorological Society
Abstract: The extent to which the tropical cyclone (TC) track forecast error of a consensus model (CONU) routinely used by the forecasters at the National Hurricane Center can be predicted is determined. A number of predictors of ...
Effect of Ship Heating on Dry-Bulb Temperature Measurements in GATE
Publisher: American Meteorological Society
Abstract: The effect of ship heating on dry-bulb temperature measurements made during GATE is investigated. It is found that measurements taken on a bow boom are less affected than those taken on the ship's bridge. It is also seen ...
Satellite Data Assimilation Using NASA Data Systems Test 6 Observations
Publisher: American Meteorological Society
Abstract: Two assimilation schemes are described in which continuous indirect insertion of satellite-derived temperatures is performed, using a global primitive equation forecast model. Both schemes employ a relatively simple indirect ...
The Navy's Operational Atmospheric Analysis
Publisher: American Meteorological Society
Abstract: In January of 1988, significant upgrades were made to the Navy Operational Global Atmospheric Prediction System (NOGAPS). Among these improvements was the implementation of a multivariate optimum interpolation analysis ...
Assimilation of Synthetic Tropical Cyclone Observations into the Navy Operational Global Atmospheric Prediction System
Publisher: American Meteorological Society
Abstract: In June 1990, the assimilation of synthetic tropical cyclone observations into the Navy Operational Global Atmospheric Prediction System (NOGAPS) was initiated at Fleet Numerical Oceanography Center (FNOC). These observations ...
Variance Spectrum Analysis of Aircraft Dew-Point Measurement System Noise
Publisher: American Meteorological Society
Abstract: A cross-spectral analysis method is developed to estimate the noise variance spectra of three or more independent measurement systems observing the same input. The noise is modeled using a first-order autoregressive process. ...
Prediction of Consensus Tropical Cyclone Intensity Forecast Error
Publisher: American Meteorological Society
Abstract: he extent to which the tropical cyclone (TC) intensity forecast error of IVCN and S5YY, consensus models routinely used by forecasters at the National Hurricane Center and the Joint Typhoon Warning Center, respectively, ...
