Toward Automated Interpretation of Satellite Imagery for Navy Shipboard Applications
Publisher: American Meteorological Society
Abstract: The U.S. Navy has plans to develop an automated system to analyze satellite imagery aboard its ships at sea. Lack of time for training, in combination with frequent personnel rotations, precludes the building of extensive ...
Prediction of Tropical Cyclone Turning and Acceleration Using Empirical Orthogonal Function Representations
Publisher: American Meteorological Society
Abstract: Prediction of tropical cyclone motion in terms of cross-track (CT) and along-track (AT) components is proposed as an alternative to geographic (zonal and meridional) components. Since the CT and AT components are defined ...
An Evaluation of Tropical Cyclone Forecast Aids Based on Cross-Track and Along-Track Components
Publisher: American Meteorological Society
Abstract: Official and objective forecast aids for tropical cyclone tracks in the western North Pacific during 1979?83 are evaluated in terms of cross-track (CT) and along-track (AT) components relative to an extrapolated track based ...
Selection of Optimal Tropical Cyclone Motion Guidance Using an Objective Classification Tree Methodology
Publisher: American Meteorological Society
Abstract: A number of tropical cyclone track forecast aids are available to the forecasters at the Joint Typhoon Warning Center (JTWC) at Guam. These aids typically provide conflicting guidance and no single aid provides consistently ...
Segmentation of Satellite Imagery Using Hierarchical Thresholding and Neural Networks
Publisher: American Meteorological Society
Abstract: A significant task in the automated interpretation of cloud features on satellite imagery is the segmentation of the image into separate cloud features to be identified. A new technique, hierarchical threshold segmentation ...
Dynamical–Statistical Model Forecasts of Southern Hemisphere Tropical Cyclones
Publisher: American Meteorological Society
Abstract: The Navy Nested Tropical Cyclone Model (NTCM) is evaluated for performance on Southern Hemisphere storms near Australia. East of 135°E the model exhibits mean forecast errors of 246, 467, and 694 km at 24, 48, and 72 h, ...
An Expert System Approach for Prediction of Maritime Visibility Obscuration
Publisher: American Meteorological Society
Abstract: An Expert system for Shipboard Obscuration Prediction (AESOP), an artificial intelligence approach to forecasting maritime visibility obscurations, has been designed, developed, and tested. The problem-solving model for ...
Machine Learning of Maritime Fog Forecast Rules
Publisher: American Meteorological Society
Abstract: In recent years, the field of artificial intelligence has contributed significantly to the science of meteorology, most notably in the now familiar form of expert systems. Expert systems have focused on rules or heuristics ...
Beta Test of the Systematic Approach Expert System Prototype as a Tropical Cyclone Track Forecasting Aid
Publisher: American Meteorological Society
Abstract: The authors have developed error mechanism conceptual models with characteristic track departures and anomalous wind or sea level pressure patterns for dynamical tropical cyclone track predictions primarily occurring in ...
Forecasting Tropical Cyclone Motion Using Empirical Orthogonal Function Representations of the Environmental Wind Fields
Publisher: American Meteorological Society
Abstract: Tropical wind fields from the U.S. Navy Global Band Analyses (GBA) are studied to depict the synoptic flow surrounding tropical cyclones. The composite fields of the zonal and meridional wind components on a grid centered ...
