The Test for Automatic Neph-analysis Chart

/Jn£I? WB* 'WWJE&**

Shingo Osano and Masakatu Ishikawa

Abstract

The skillfulmeteorologists analysed satelliteimages with various meteorological data and

make neph-analysis charts consisted with "cloud area" by means of outlines.

Due to construct an automatic neph-analysis chart, prototype programme was made and

compared with subjectiveneph-analysis charts. It was sure that "cloud area" was just associat-

ed with meteorological disturbance and consisting of very dense cloud, and outline of "cloud

area" was considerably smoothed.
