Analysis for Vertical Wind Shear Change at Coastal Area according to the Sea Surface Temperature

Abstract

This study is to analyze the effect of the sea surface temperature (SST) on the distribution of vertical wind speed in the atmospheric boundary layer of coastal area. It is generally known that coastal areas are more susceptible to various weather factors due to interannual variation of sea surface temperature than inland areas. Therefore, the goal of this study is to analyze the relationship between sea surface temperature using the Era-interim reanalysis data and wind speed data based on the meteorological tower data of Hovsore, wind power test bed area in the Danish coastal area. Furthermore, the possibility of disaster caused by vertical wind shear due to sea surface temperature change is discussed. As a result of correlation analysis between the wind data of the meteorological tower and the sea surface temperature of the reanalysis data, the wind speed and the vertical wind shear from the sea are stronger than those from the inland and they are sensitive to the seasonal sea surface temperature changes.
