Tropical Cyclone Floaters
|Text bulletins disseminated by 0400Z, 1000Z, 1600Z, and 2200Z describing the position and intensity estimates for tropical disturbances and tropical cyclones in the Eastern and Southern Hemispheres.||
Subjective position estimates of tropical disturbances and cyclones across the globe using a variety of microwave sensors.
The Total Precipitable Water (TPW) is a unified, meteorologically significant TPW field blending AMSU, SSM/I and GPS TPW together, for non-gap global coverage.
|The eTRaP is a simple ensemble that allows for the generation of probabilistic forecasts of rainfall in addition to deterministic rainfall totals.|
|MTCSWA combines information from several data sources to create a mid-level wind analysis which is then adjusted to the surface. Eight products are displayed, most notably an inner core scale surface wind analysis.||
The Tropical Cyclone Formation Probability Product provides an estimate of the probability of tropical cyclone formation within the next 24 hours in 1 by 1 degree latitude/longitude areas from 45S to 45N and 0 to 360E.|
|The ADT provides an automated, objectively-derived estimate of the tropical cyclone location and intensity using the latest official forecast bulletins from the Joint Typhoon Warning Center (JTWC) and from Regional Specialized Meteorological Centers (RSMC), such as the National Hurricane Center (NHC) and the Central Pacific Hurricane Center (CPHC).|

| The Joint Typhoon Warning Center (JTWC) provides tropical cyclone analysis, forecast and warning support for the Department of Defense, and other US Government assets in the Pacific and Indian Oceans. || Regional Specialized Meteorological Centers (RSMC) provide official position, intensity and forecast tracks for tropical cyclones within their areas of resonsibility.
New Delhi, India
Users are reminded that posted SPSD position and intensity estimates are based on the application of the Dvorak technique to satellite imagery. Official determinations of systems' status, location and intensity are provided by the Regional Specialized Meteorological Centers listed above.|
