Abstract: An objective technique for estimating tropical cyclone (TC) intensity is proposed in the context of GMS-5 blackbody temperatures (TBB) from 15 TCs over the northwestern Pacific Ocean during 2001—2002 and multiple TBB factors taken form the TC intensity-representative cloud system as well as the latitude of TC cores and the data from the Tropical Cyclones Annual that are treated by stepwise regression, leading to an objective scheme for TC intensity estimation after a number of experiments, with the complex correlation coefficient being more than 0.80. The scheme-estimated TC central pressures show the complex correlation coefficient of 0.89 between 24 h running mean and the annual, used samples having ±10 hPa difference between the two sources are more than 83%, the result is close to the result reported by US researchers. Also, validations of two TCs recorded in 2000 is successful, it is likely that the scheme will replace the subjective technique of Dvorak in current use to be a new method on a operational basis.
