Abstract
Using PSU/NCAR mesoscale model MM5, database of 3km×3km local meteorological fields over Chubu and Kinki districts was created for one year from April 2001 to March 2002. The meteorological elements (wind velocity and direction, pressure, temperature, mixing ratio, solar radiation and precipitation) included in the database were validated with surface observations from 42 stations. As a result, it was found that the accuracies of calculation for pressure, temperature and mixing ratio are enough to be used for practical applications as hourly values. Calculated wind speed and direction have root-mean-square errors of about 3.0m/s and 40 to 50 degrees respectively, which are somewhat large to be used as substitutes for hourly observations. For solar radiation and precipitation, their accuracies of calculation are overall not sufficient due to the inaccurate reproduction of clouds in the model, but the calculated values can reach to a practical level as far as they are used as long-term averages such as monthly or yearly values.
