Abstract

The purpose of this research is to select representative observation stations for winter observation equipment performance tests and to present indoor and outdoor conditions for performance tests by considering snowfall, snowfall days, latitude, and altitude distribution for observation stations operated by the Korea Meteorological Administration. Using the snowfall data observed during the winter for 30 years (1981-2010), ten representative observation stations are selected to consider the classification of snowfall days by class, latitude, and altitude distribution of observation stations. As a result of analysis, the suitable point for outdoor experiments was selected as Daegwallyeong, the average number of snowfall days and snowfall days of 5cm or more were 57.5 and 13.2 days, respectively. The indoor experimental conditions are considered to be suitable under temperatures of –15 to 5℃ and humidity of 50% or higher. Results of this research can be used as basic information for conditions and test beds for performance tests of equipment that can respond to heavy snow disasters in winter.

본 연구는 기상청에서 운영하고 있는 관측지점을 대상으로 강설량과 강설 일수를 위도와 고도 분포를 고려하여 겨울철 강설 측정 장비의 성능 시험을 위한 대표 관측지점과 실내외실험을 위한 조건을 제시하기 위해 수행하였다. 30년간(1981~2010) 관측한 겨울철 강설 자료를 사용하여 강설 일수의 계급별 분류, 관측지점의 위도 및 해발고도 분포를 고려하여 대표관측지점 10개소를 선정하였다. 분석결과 실외 실험에 적합한 지점은 연평균 강설 일수와 5 cm 이상의 적설 일수가 각각 57.5일, 13.2일로 나타난 대관령을 선정하였다. 실내 실험조건은 기온 –15~5℃ 습도 50% 이상의 조건이 적합하다고 사료된다. 연구 결과는 겨울철 대설재난에 대응할 수 있는 장비의 성능 시험을 위한 조건과 실외 실험장소에 대한 기초자료로 활용이 가능할 것으로 판단된다.
