A computer program was developed to localize accurately low-level jet streams related to the long-distance migration of the planthoppers and to predict the time of their immigration to Japan. The program outputs the contour map of the wind speed, and mesh map of the wind direction and speed. Weather data used in this program included the wind direction and speed on the 850mb weather chart received by radio facsimile recorder from 74 meteorological stations.
