The strong wind fields over Kyushu Island were simulated numerically during Typhoon Songda passed by in 2004. The mesoscale climate model, JMA NHM (Japan Meteorological Agency nonhydrostatic model) was used for the calculation. The predicted wind fields were examined comparing with the observed records. The wind speeds and directions were recorded by the anemometer's network, NeWMeK, in Kyushu Island. The time variation of calculated wind speed with 1km horizontal meshes was equivalent to the ten-minutes time averaged values of observed wind speed. The values of calculated wind speed were higher than the ten-minutes time averaged wind speed. But the calculated wind speed were well correlated to the maximum wind gust of NeWMek observation in the area with strong wind. The variation of wind direction showed good correlation
