GOES Wind Index (WINDEX)

14

GOES Dry Microburst Potential Index (DMPI)

Likelihood of high based, low precipitation microbursts - West/Central US

15

GOES Microburst Day Potential Index

This index is useful for showing the potential for wet microbursts in the southeast United States. An index value approaching 1 represents a high risk.

16

GOES High Density Winds

Winds Derived in Several Categories

• Cloud-Drift IR Winds (Imager)

• Water Vapor Winds (Imager)

• Visible Winds (Imager)

• Water Vapor Winds (Sounder)

Implementation Schedule/Issues

Prioritized AWIPS Satellite Product Requirements Completed by NWS/OM;Incorporated Into SPSRB (Satellite Products and Services Review Board) List for Resource Allocation

AWIPS ‘Build 5’ is First Opportunity for Including New Products/Applications in AWIPS System - Early/Mid 2000

NWS Will Accept “Experimental” Products Pending Operational Implementation at NESDIS; ORA (Office of Research and Applications) Will Distribute Routine “Experimental” Products

Many New AWIPS Products Currently Available on Internet

AWIPS Applications Software Needed for Product Display and Analysis
