기상관측에 의한 일기예보가 수치예보로 발전하면서 정확도가 획기적으로 향상되고 있다. 인류가 기원전부터 실시해온 일기예보는 하늘의 징조를 보고 예측하는 한 지점 관측시대, 여러 지역의 관측을 수집하여 예측하는 지상 일기도시대, 대지의 상공까지 관측하는 업체 분석시대를 거쳐 오늘날의 수치 예보시대로 발전한 것이다. 수치예보를 실행하기 위해서는 방대한 조직과 예산, 인원이 필요하며 한나라의 힘만으로는 불가능하여 국가간의 협력이 이루어져야 한다.

This paper is written for the purpose of obtaining the information about the weather easily by the development of weather forecast system sensing temperature, humidity, and atmospheric pressure as key information. For this, data is obtained from the Weather Bureau, and analyzed in order to set a standard of weather forecast from the collected data. The pressure sensor and temperature-humidity sensor are fabricated using the piezoresistive effect of semiconductor, which are used to collect data. The weather forecast system is made using microprocessor.

본 논문에서는 음성인식을 이용한 일기예보 서비스 시스템을 소개한다. 이 서비스는 사용자가 지역명을 말하면 음성인식을 통해 그 지역명을 인식하여 일기예보를 들려주며, 차세대 지능망(AIN: Advanced Intelligent Network)에 구현되었다. 음성인식은 IP(Intelligent Peripheral)에서 이루어지며. 음성인식 실험 결과, 실험실과 시스템 상에서 각각 95.04%와 93.81%의 인식율을 보여 주었다.

"기상 예보ㆍ통보때 예보관의 이름을 함께하는 '예보관 실명제'를 도입해 앞으로 일기예보의 적중률을 높이는데 최선을 다하겠습니다" 신임 기상청장 문승의 박사는 다짐한다. 올 여름 우리나라의 이상기상은 엘니뇨현상의 간접 영향이라고 밝힌 문청장은 앞으로 가뭄지수, 부패지수, 시도별 냉난방지수와 자외선지수 등 예보기능을 확대해 나갈 계획이라고 말했다.

The defining of weather forecasting regions is possible. since the representativeness of regional weather can by reasonably clarified in terms of weather entropy and the use of information ratio. In this paper, the weather entropy and information ratio were derived numerially from using the information theory. The typical weather characteristics were clarified and defined in the homogeneous weather forecasting regions of the southern parts of Korea. The data used for this study are the daily precipitation and cloudiness during the recent five years (1990-1994) at 42 stations in southern parts of Korea. It is divided into four classes of fine, clear, cloudy and rainy. The results are summarized as follows: 1. The maximum value of weather entropy in study area is 2.009 vits in Yosu in July, and the minimum one is 1.624 bits in Kohung in October. The mean value of weather entropy is maximal in July, on the other hand, minimal in October during four season. The less the value of entropy is, the stabler the weather is. While the bigger the value of entropy is, the more changeable the weather is. 2. The deviation from mean value of weather entropy in southern parts of Korea, with the positive and the negative parts, shows remarkably the distributional tendency of the east (positive) and the west (negative) in January but of the south (positive) and the north (negative) in July. It also clearly shows the distributional tendency of the east (postive) and the west(negative) in the coastal region in April, and of X-type (southern west and northern east: negative) in Chiri Mt. in October. 3. In southern parts, the average information ratio maximaly appear 0.618 in Taegu area in July, whereas minimally 0.550 in Kwangju in October. Particularly the average information ratio of Pusan area is the greatest in April, but the smallest in October. And in Taegu, Kwangju, and Kunsan, it is the greatest in April, January, and July, but the smallest in Jyly, July, and pril. 4.The narrowest appreance of weather representativeness is in July when the Kwangju is the center of the weather forecasting. But the broadest one is in April when Taegu is the center of weather forecasting. 5. The defining of weather forecasting regions in terms of the difference of information ratio most broadly shows up in July in Pusan including the whole Honam area and the southern parts of Youngnam when the Pusan-Taegu is the basis of the application of information ratio. Meanwhile, it appears most broadly in January in Taegu including the whole southern parts except southern coastal area.

The purpose of this study is to analyse the accuracy of weather forecasts of temperature, precipitation probability , and sky condition and to evaluate the applicability of weather forecasts for the estimation of potential evapotranspiration for irrigation scheduling. Five weather station s were selected to compare forecasted and measured climatcal data. The error between forecasted and measured temperature was calculated and discussed. The accuracy of temperature forecast using relative frequency of the error was calculated . The temperature forecasting showed considerably high accuracy. Average sunshine hours for forecasted sky conditions were calculated and showed reasonable quality. From the reliability graphs, the forecasting precipation probabililty was reliable. Potential evapotranspirations were calculated and compared using forecast and measured temperatures. The weather forecast is considered usable for irrigation scheculing.
