An objective technique for estimating present tropical cyclone locations

A techhique is developed and tested for estimating objectively the location of a tropical cyclone from a variety of fixes. The western North Pacific climatology and persistence track forecast technique is used to generate a potential track from each fix. A tentative warning position is interpolated from a smooth curve that is fit to the future and past positions. When multiple fixes are available, weighting functions are applied to account for the expected accuracy and the timeliness of each fix. Thus, the objective technique provides an efficient tool for the forecaster to use in establishing the present location of the tropical cyclone. -from Authors
