An Alternate to the HURRAN (Hurricane Analog) Tropical Cyclone Forecast System.

COM7210351

Publication Date	1972
Personal Author	Neumann, C. J.
Page Count	34
Abstract	The HURRAN (Hurricane Analog) system is one of several techniques from which the National Hurricane Center derives objective guidance preparatory to the issuance of tropical cyclone track forecasts. One shortcoming of the HURRAN system is its inability to provide objective guidance when insufficient analogs are found. Accordingly, an alternate regression equation system known as CLIPER (Climatology and Persistence) was developed. This paper describes the derivation, application and errors of the CLIPER system.
