Research Abstract

Downscaleprediction system of meso-scale phenomena has been developed with its applications to agriculture and aviation. To advance its predictive skill, further efforts are required to improve physics parameterization, and to optimize initial and lateral boundary conditions. In agriculture, predictabilities have been studied on local sever wind (Kiyokawadashi) and potential forecast of Magnaporthe grisea. Feasibility study has been made on monitoring/very short-range prediction system for aviation weather on the basis of data assimilation of Doppler lidar into downscale system.
