초록

GPS 라디오존데는 정밀 기상 센서와 GPS 위성 네트워크에서 생성된 데이터를 사용하여 풍선이 터질 때까지 상승하면서 종관 규모의 연직 관측을 수행하도록 설계되었다. GPS 라디오존데는 정밀한 온도, 습도 및 기압 센서를 내장하고 있다. GPS 라디오존데를 사용하여 2016년 3월 9일 18시부터 2016년 3월 12일 06시까지 서해의 세 섬에서 대기경계층을 집중관측하였고, 야간 안정층이 억제되고 오히려 야간 혼합층이 발달되는 사례를 조사하였다. 야간 혼합층은 3월 9일에 지표 열플럭스에 의해 발달된 반면에 3월 10일 혼합층 높이가 가장 높았던 21시에는 시어 생성이 가장 높았다. 난류운동에너지를 생산하는 수평 바람의 연직 층밀림과 표면 열플럭스가 야간에도 혼합층을 성장시키는 데 중요한 역할을 하였다.

The GPS radiosonde is designed to conduct a full synoptic sounding to balloon burst using data generated from precision meteorological sensors and the GPS satellite network. The GPS radiosonde include proven, accurate temperature, humidity and capacitance aneroid pressure sensors. The atmospheric boundary layer was intensively observed in three islands of the west sea from 18 LST on March 9, 2016 to 06 LST on March 12, 2016. We investigated the restriction of nocturnal stable layer and rather the development of the mixed layer at night. On March 9, nocturnal mixed layer was developed by buoyancy heat flux. On the other hand, on March 10, the shear production was higher especially at 21 LST when the mixed layer height was the highest during the intensive observation period. The wind shear and the surface heat flux which produce the turbulent kinetic energy played an important role to grow the mixed layer even at night.
