The nocturnal gust of greater than 15KTS, occurring in the stable weather conditions due to the influence of the high-pressure system at Daegu Airport, has been carefully analyzed by the synoptic scale, mesoscale and topographical analysis. This process ends up with following results.
First of all, the synoptic analysis of the 850hPa upper air always shows the thermal trough in the korean Eastern Sea, which causes the surface of discontinuity, as the land is relatively warmer than the sea.
Then, it is classified into sea-breeze front-like pattern and the other by the mesoscale analysis.
Lastly, the topographical analysis proves that Daegu is susceptible to an easterly wind, which tends to become faster when passes through Gyeongsan. It happens as Daegu Airport is located in a valley, which is 70km away from Pohang in a straight line, and this region is joined easterly.
