The Dvorak Tropical Cyclone Intensity Estimation Technique
T HE DVORAK TECHNIQUE LEGACY. The Dvorak tropical cyclone (TC) intensity estimation technique has been the primary method of monitoring tropical systems for more than three decades. The technique has likely saved tens of thousands of lives in regions where over one billion people are directly affected by TCs (commonly called hurricanes, typhoons, or cyclones). The Dvorak technique’s practical a...
متن کاملA Multiple Linear Regression Model for Tropical Cyclone Intensity Estimation from Satellite Infrared Images
An objectively trained model for tropical cyclone intensity estimation from routine satellite infrared images over the Northwestern Pacific Ocean is presented in this paper. The intensity is correlated to some critical signals extracted from the satellite infrared images, by training the 325 tropical cyclone cases from 1996 to 2007 typhoon seasons. To begin with, deviation angles and radial pro...
متن کاملSatellite-Derived Tropical Cyclone Intensity in the North Pacific Ocean Using the Deviation-Angle Variance Technique
The deviation-angle variance technique (DAV-T), whichwas introduced in theNorthAtlantic basin for tropical cyclone (TC) intensity estimation, is adapted for use in the North Pacific Ocean using the ‘‘best-track center’’ application of the DAV. The adaptations include changes in preprocessing for different data sources [Geostationary Operational Environmental Satellite-East (GOES-E) in the Atlan...
متن کاملEstimating Tropical Cyclone Intensity from Infrared Image Data
This paper describes results from a near-real-time objective technique for estimating the intensity of tropical cyclones from satellite infrared imagery in the North Atlantic Ocean basin. The technique quantifies the level of organization or axisymmetry of the infrared cloud signature of a tropical cyclone as an indirect measurement of its maximum wind speed. The final maximum wind speed calcul...
متن کاملA Novel Comparison Approach for Tropical Cyclone Satellite Images Using Angle Features
Conventionally, the identification of Tropical Cyclones (TCs) has been highly dependent on subjective human judgment applied to vast amounts of data extracted from satellite images. The most popular approach to comparing two given TCs is to measure the distance between various contour points of the TC extracted from a satellite image. However, this measure has a very high computational cost as ...
