Microwave Positions MTCSWA
Sample Microwave Graphic Subjective position estimates of tropical disturbances and cyclones across the globe using a variety of microwave sensors.

ATCF Format
Sample MTCSWA Image 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.

Sample TPW Graphic 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.
Blended TPW | TPW percent
Sample eTrap Graphic The eTRaP is a simple ensemble that allows for the generation of probabilistic forecasts of rainfall in addition to deterministic rainfall totals.

Sample TCFP Graphic 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. Sample ADT Graphic 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).

Sample NHC Image The National Hurricane Center is the Regional Specialized Meteorological Center (RSMC) for the Atlantic Basin and is a resource for official tropical cyclone positions, intensities and forecast tracks.

Sample OSEI Graphic High-resolution, detailed imagery of tropical cyclones as detected in remotely sensed data.


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.
