Description

Patterns of total ozone distribution around typhoons were studied on NIMBUS-7 TOMS (Total Ozone Mapping Spectrometer) data, where the typhoon positions were determined by the typhoon track charts provided by Japan Meteorological Agency (JMA). Out of 185 samples on typhoon in the area 0-45N in latitude and 100-180E in longitude, in the period of four months, July through October (typical typhoon season), each year from 1979 through 1989, 80 typhoons showed definite signatures. Characteristic patterns were recognized in 243 samples. The patterns were roughly classified into 2 types : Central Dense (CD)-type and Spiral (S)-type. A CD-type has a dense ozone core on the typhoon position surrounded by a thin density fosse. An S-type shows a pattern, into which ozone dense stripes swirled. It is found that the S-type appears when a typhoon is coupled with a trough of a large scale pressure system in a westerly wind zone, and that the life time of the CD-type is comparatively short.
