초록

본 연구는 겨울철 적설 관측에 사용되는 전도형 강수량계 가열 시스템의 최적 온도, 위치, 제어 방식을 도출하기 위해 수행하였다. 수수구, 외부, 내부를 가변적으로 제어 가능한 전도형 강수량계를 제작하여 실내·외 실험을 수행하였다. 실내 실험은 강수량계 가열시스템의 성능비교와 적정온도를 도출하기 위해 항온항습챔버에서 수행되었다. 이후 다설지인 대관령에 위치한 구름물리선도센터에서 실외실험을 수행하여 실내실험 결과를 검증하였다. 분석 결과, 수수구의 가열 온도는 10~30℃, 내부 가열 온도는 70℃가 최적으로 확인되었다. 또한, 측정 지연을 최소화하기 위한 가열 장치의 최적 위치는 강수량계 외부, 수수구 테두리, 수수구 수직면으로 확인되었다. 본 연구 결과는 겨울철 고체 강수 측정을 위한 강수량계 가열 시스템의 운영 조건에 대한 기초자료로 활용이 가능할 것으로 판단된다.

The purpose of this research is to derive the optimal temperature, location, and heating control system for a tipping bucket rain gauge heating system used for observing snowfall during winter. We conducted indoor and outdoor experiments by manufacturing a tipping bucket rain gauge that can be variably controlled for heating at the funnel, exterior, and interior, and indoor and outdoor. The indoor experiments involved using a temperature and humidity chamber to compare the performance and derive the appropriate temperature of the precipitation gauge heating system. Subsequently, the outdoor experiments were carried out at the Cloud Physics Observation Center located in Daeguallyeong, heavy snowfall region, to validate the findings. The analysis result was derived that the heating temperature of the funnel should be set at the 10 to 30℃, while the internal heating temperature should be 70℃. Furthermore, the optimal locations for the heating devices, which aim to minimize measurement delay, were identified as the exterior of the rain gauge, the rim of the funnel, and the vertical surface of the funnel. Our result shows that used as the basis for the operating conditions of precipitation gauge heating systems for solid precipitation measurement in winter.
