호남지방 고층관측자료동화가 수치기상예보에 미치는 영향에 관한 연구 = A Study on the Influence of Aerological Observation Data Assimilation at Honam Area on Numerical Weather Prediction

다국어 초록 (Multilingual Abstract)

Aerological observation at Heuksando located in south-western part of Koran Peninsula has been started at 1 June 2003. In order to clarify the improvement of meteorological prediction quality, it is necessary to compare between
aerological data observed at Gawngju and Heuksando and to make clear the influence of Heuksando data assimilation. Therefore numerical simulations were carried out with High resolution meterological prediction system based on MM5 (The 5th Generation Mesoscale Model). The pattern of wind and temperature field observed at Heuksando and Gwangju are different due to land surface friction and sensible heat flux at surface and the wind field simulated with Gwangju and Heuksando aerological data agree well with observation wind field. Although the amount of precipitation in these experiments is underestimated, the area and starting time of precipitation around Honam province in case with Heuksando data is more reliable that without the data.
