SPSD Tropical Program Products:

Dvorak Classifications Bulletins
Sample Dvorak Image Subjective position and intensity estimates of tropical disturbances and cyclones across the globe using the internationally recognized Dvorak technique.

ATCF Format
ATCF Info|ATCF Format Description
Sample Bulletin Image Text bulletins disseminated by 0100Z, 0700Z, 1300Z, and 1900Z describing the position and intensity estimates for tropical disturbances and tropical cyclones globally.

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

ATCF Format
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).

eTRaP TCFP
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 24to 48 hours in 1 by 1 degree latitude/longitude areas from 45S to 45N and 0 to 360E.

MTCSWA MWTC
Sample MTCSWA Graphic 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 AMUSTC Graphic Microwave-based Tropical Cyclone (TC) Products provide estimates of tropical cyclone maximum wind speed, minimum sea level pressure, radii of 34, 50, and 64 knot winds in 4 quadrants relative to the storm center, and balanced horizontal winds from 1000 to 200 mb within 600 km of the storm center.

Brazil National Institute of Meteorology NCEP International Desk
INMET Image The Brazil National Institute of Meteorology is responsible for issuing the official warning for tropical cyclones in the South Atlantic Basin. NCEP Image NOAA's Weather Prediction Center provides visiting scientists meteorological training with an emphasis on the operational use and application of numerical model products.

Disclaimer:
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.
