  • This study was conducted to investigate the characteristics of meteorological environment variation before and after construction of Nak-dong river estuary barrage. We used meteorological data(air temperature, precipitation, relative humidity, visibility, wind) at Gimhae airport meteorological station. The construction of river estuary barrage can change climate at the neighboring districts and influence human's health and vegetable. The construction of Nakdong river estuary barrage brought rise of temperature, decrease of relative humidity and increase of poor visibility frequency.

  • Dust-storm is one of the heaviest hazardous weather which frequently affects most part of northern China in spring. Satellite multi-spectral observations can provide significant information for detecting and quantitative determining the property of dust-storm . An algorithm to monitor dust-storm automatically was developed based on satellite observation. The algorithm utilizes split widows technique and spectral classification technique and also developed a new dust remote sensing product Infra -red Difference Dust Index (IDDI) proxy dust-loading dataset using GMS-5.

  • This study examined the impact of change of land-use and meteorological condition due to urbanization on heat environment in Seoul metropolitan area over a decade (2000 and 2009) using Weather Research and Forecasting (WRF)-Urban Canopy Model (UCM). The numerical simulations consist of three sets: meteorological conditions of (1) October 2000 with land-use data in 2000 (base simulation), (2) October 2009 with land-use data in 2000 (meteorological condition change effect) and (3) October 2009 with land-use data in 2009 (both the effects of land-use and meteorological condition change). According to the experiment results, the change of land-use and meteorological condition by urbanization over a decade showed different contribution to the change of heat environment in Seoul metropolitan area. There was about $1^{\circ}C$ increase in near-surface (2 m) temperature over all of the analyzed stations due to meteorological condition change. In stations where the land-use type changed into urban, large temperature increase at nighttime was observed by combined effects of meteorological condition and land-use changes (maximum $4.23^{\circ}C$). Urban heat island (UHI) over $3^{\circ}C$ (temperature difference between Seoul and Okcheon) increased 5.24% due to the meteorological condition change and 26.61% due to the land-use change. That is, land-use change turned out to be contributing to the strengthening of UHI more than the meteorological condition change. Moreover, the land-use change plays a major role in the increase of sensible heat flux and decrease of latent heat flux.

  • Low-level wind shear (LLWS) events on glide path at Jeju International Airport (CJU) are evaluated using the Aircraft Meteorological Data Relay (AMDAR) and Korea Meteorological Administration Post-Processing (KMAPP) with 100 m spatial resolution. LLWS that occurs in the complex terrains such as Mt. Halla on the Jeju Island affects directly aircraft approaching to and/or departing from the CJU. For this reason, accurate prediction of LLWS events is important in the CJU. Therefore, the use of high-resolution Numerical Weather Prediction (NWP)-based forecasts is necessary to cover and resolve these small-scale LLWS events. The LLWS forecasts based on the KMAPP along the glide paths heading to the CJU is developed and evaluated using the AMDAR observation data. The KMAPP-LLWS developed in this paper successfully detected the moderate-or-greater wind shear (strong than 5 knots per 100 feet) occurred on the glide paths at CJU. In particular, this wind shear prediction system showed better performance than conventional 1-D column-based wind shear forecast.

  • 도시화 효과가 여름 강수에 미치는 영향을 분석하기 위해 2010년 8월 13일부터 9월 3일까지 수도권 집중관측(ProbeX-2010)을 수행하였다. 분석 결과, 다음의 두 가지 현상들이 발견되었다. 첫째, 관측 기간 동안 약한 강수(${\leq}1\;mm\;hr^{-1}$)가 다른 지역보다 서울 풍하측 지역에서 더 자주 발생하였으며, 이는 최근 5년(2006-2010) 자료에서도 확인되었다. 약한 강수는 주로 서울 풍하측 산악 지역에서 야간에 더 자주 발생하였기 때문에 이는 도시지형 뿐만 아니라 산악 지형의 복합적인 효과로 여겨진다. 둘째, 간헐적으로 대류 시스템이 서울 풍하측에서 급격하게 발달해 호우를 야기했다. 이는 특히 8월 27일 1300-1500 KST의 일련의 레이더 영상에서 뚜렷하게 확인되었다. 본 연구에서는 이 강수 사례에 대한 종관 국지적 날씨 특성과 고층 대기 특성을 자세히 분석하였다. 그 결과 도시지형과 연관된 지표 현열 증가뿐만 아니라 조건부 불안정 대기 상태(특히 대기 하층)와 대기 하층의 습기 유입이 도시화 효과와 연관된 대류성 호우를 야기하는 중요한 요소로 제시되었다.

  • kDomestic studies on meteorologicaldata have been carried out, however they were mostly not constant but limited to fragment compilation. The studies on solar energy, among others, have been relatively active but the measurement of solar irradiance is also limited to some extent. This study, in an effort to identify the difference in data between solar radiance and cloud cover, was intended to compare and analyze the typical meteorological data developed by Korean Solar Energy Society with the solar irradiance calculated using the typical meteorological data and cloud cover data provided by current simulation program. Monthly average solar irradiance from the meteorological data (ISO TRY) of Korea's typical meteorological data which was actuallymeasured appeared to be far below the monthly solar irradiance from the American Department of Energy. The solar irradiance calculated based on cloud cover indicates very limited difference between the two data, so the solar irradiance measured by Korean typical metrologicaldata (ISO TRY) indicated the similar value, which demonstrates the solar irradiance data from Korean Meteorological Administration is more accurate than those US National Weather Center.

  • Journal of the Korean Meteorological Society (JKMS) is confronted by a huge challenge. Following the long-term plan of the Korean Meteorological Society (KMS), the JKMS has entered a new era in 2006 in the sense that the all papers are published in English. Tremendous efforts are needed to accomplish the original goal of JKMS becoming an internationally recognized journal. A forum was held in this connection with the subject of the vitalization of the JKMS at the Spring Meeting of the Korean Meteorological Society held at Gwangju, 2006. A number of special topics were presented at the forum and active and vigorous discussions followed. Professor Dong-Kyou Lee presented strategies to increase the number of submission to the JKMS. Professor Seon Ki Park gave a presentation on how JKMS can grow into the SCI journal. The Editor-in-Chief of JKMS, professor H. Joe Kwon introduced the on-line review system of JKMS which had launched in 2006. This manuscript is presented on the basis of the presentations and the discussions at the forum for the purpose of finding the way in aiming the direction of the long-term goal of the KMS.
