RISFORECASTING 700-MB. DEWPOINT DEPRESSION BY A 3-DIMENSIONAL TRAJECTORY TECHNIQUE
Publisher: American Meteorological Society
Abstract: Quasi 3-dimensional forecasts of 700-mb. dewpoint depression are made for periods up to 36 hours using observed 700-mb. charts and initial and 12-hr. forecast vertical motion charts from the JNWP Unit's ?thermotropic model.? ...
RECORDED PRESSURE DISTRIBUTION IN THE OUTER PORTION OF A TORNADO VORTEX
Publisher: American Meteorological Society
Abstract: Records are presented from nine barographs located in a small area close to the path of a tornado. The pressure profile in the range from 720 to 2,300 feet from the path of the tornado center as determined from the barograph ...
Assessing the Accuracy of the Cloud and Water Vapor Fields in the Hurricane WRF (HWRF) Model Using Satellite Infrared Brightness Temperatures
Publisher: American Meteorological Society
Abstract: n this study, cycled forecast experiments were performed to assess the ability of different cloud microphysics and cumulus parameterization schemes in the Hurricane Weather Research and Forecasting (HWRF) Model to accurately ...
Assimilation of High-Resolution Satellite-Derived Atmospheric Motion Vectors: Impact on HWRF Forecasts of Tropical Cyclone Track and Intensity
Publisher: American Meteorological Society
Abstract: t is well known that global numerical model analyses and forecasts benefit from the routine assimilation of atmospheric motion vectors (AMVs) derived from meteorological satellites. Recent studies have also shown that the ...
Geostationary Doppler Radar and Tropical Cyclone Surveillance
Publisher: American Meteorological Society
Abstract: he potential usefulness of spaceborne Doppler radar as a tropical cyclone observing tool is assessed by conducting a high-resolution simulation of an intense hurricane and generating synthetic observations of reflectivity ...
Probabilistic Prediction of Tropical Cyclone Intensity with an Analog Ensemble
Publisher: American Meteorological Society
Abstract: AbstractAn analog ensemble (AnEn) technique is applied to the prediction of tropical cyclone (TC) intensity (i.e., maximum 1-min averaged 10-m wind speed). The AnEn is an inexpensive, naturally calibrated ensemble prediction ...
A Feed Forward Neural Network Based on Model Output Statistics for Short-Term Hurricane Intensity Prediction
Publisher: American Meteorological Society
Abstract: AbstractA feed forward neural network (FFNN) is developed for tropical cyclone (TC) intensity prediction, where intensity is defined as the maximum 1-min average 10-m wind speed. This deep learning model incorporates a ...
