Abstract

With the development of technology and the advancement of weather forecasting models and prediction methods, higher performance weather forecasting software has been developed, and more precise and accurate weather forecasting is possible by performing software using supercomputers. In this paper, the weather forecast model used by six major countries is investigated and its characteristics are analyzed, and the Korea Meteorological Administration currently uses it in collaboration with the UK Meteorological Administration since 2012 and explains the GloSea However, the existing GloSea was conducted only on the Meteorological Administration supercomputer, making it difficult for various researchers to perform detailed research by specialized field. Therefore, this paper aims to establish a standard experimental environment in which the low-resolution version based on GloSea6 currently used in Korea can be used in local systems and test it to present the localization of low-resolution GloSea6 that can be performed in the laboratory environment. In other words, in this paper, the local portability of low-resolution Globe6 is verified by establishing a basic architecture consisting of a user terminal-calculation server-repository server and performing execution tests of the software.

컴퓨터 기술의 발전과 기상예보 모델 및 예측방식의 고도화에 따라 더 고성능의 기상예측 소프트웨어가 개발되었으며 슈퍼컴퓨터를 활용한 소프트웨어 수행으로 더욱 정밀하고 정확한 기상예보가 가능하게 되었다. 본 논문에서는 주요 6개국이 사용하고 있는 기상예측 예보 모델을 조사하여 그 특징들을 분석하고 현재 한국 기상청에서 영국 기상청과 2012년부터 협업하여 사용하고 GloSea 소프트웨어에 대하여 설명한다. 그런데 기존의 GloSea는 기상청 슈퍼컴퓨터에서만 수행되어 다양한 연구자들의 전문 분야별 세분화된 연구에 어려움이 있었다. 따라서 본 논문에서는 현재 우리나라에서 사용하고 있는 GloSea6 기반의 저해상도 버전을 로컬시스템에 사용할 수 있는 표준 실험환경을 구축하고 이를 테스트해봄으로써 연구실 환경에서 수행 가능한 저해상도 GloSea6의 로컬화를 제시하고자 한다. 즉, 본 논문에서는 사용자 단말기-계산서버-리퍼지토리 서버로 구성되는 기본 아키텍처를 구축하고 해당 소프트웨어의 실행 테스트를 수행함으로써 저해상도 GloSea6의 로컬 이식성을 검증한다.
