Abstract

The height of the atmospheric boundary layer indicates the peak developed when turbulence is generated by mixing heat and water vapor, and is generally determined through thermodynamic methods. Wind profilers produce atmospheric information from the scattering of signals sent into the atmosphere. A method for making the spectrum of turbulent components, turbulent kinetic energy dissipation rate, and refractive index structure coefficient was presented to determine the atmospheric boundary layer depth. Compared with the vertical distribution characteristics of potential temperature and specific humidity based on radiosonde data, the determination method of the atmospheric boundary layer height from wind profiler output was evaluated as very useful.

대기경계층 고도는 지면의 가열로 인해 발생한 난류가 경계층 내의 열, 수증기 등을 혼합하면서 생성되는 꼭대기로 일반적으로 열역학적 방법을 통해 결정한다. 윈드프로파일러는 대기 중으로 보낸 신호의 산란 정보로 대기의 정보를 산출한다. 윈드프로파일러 관측으로 대기경계층 깊이를 결정하기 위해 난류 성분의 스펙트럼 및 난류운동에너지 소산율, 굴절지수구조계수를 산출하는 방법을 제시하였다. 라디오존데 자료를 기반으로 산출한 온위와 비습의 연직 분포 특징과 비교하여 윈드프로파일러 산출물 기반의 대기경계층 고도 결정 방법이 매우 유용한 것으로 평가되었다.
