Abstract:

Storm Motion SM is a planned initial Operational Capability IOC algorithm of the FAAs Integrated Terminal Weather System ITWS. As currently designed, this algorithm will track the movement of stormscells and convey this tracking information to the ITWS user by means of a graphic display of vectors for direction with accompanying numeric reports of storm speed, rounded to the nearest 5 nmihr increment. Recognizing that there are occasions when ITWS users could benefit from a more extended product format, Storm Extrapolated Position SEP was conceived to supplement the SM product and thereby increase its accessibility as a planning aid. This communication describes a prototype SEP design along with an analysis of its accuracy and observed performance during 1993 ITWS demonstrations in Orlando FL and Dallas TX.
