Abstract: | With black-body temperature(TBB) from GMS infrared cloud imagery for 16 tropical cyclones in 1996-1997 and domestic and overseas reports of gale by tropical cyclones as well as some conventional andshipboard wind reports, a number of conceptual charts are statistically summarized to determine ranges of gales on near gale and 10 of the storm. A method by which the radius of gale is operationally useful has beed tested. |
