This paper is a study on the distribution of the climatic elements, characteristics of change and correlation among the meteorological variable in the Chollado area. For this study the MONTHLY WEATHER REPORTS over the last ten year(1971~1980) were u^tilized. Weather station were nine in number, those of Kunsan, Puan, Chonju, Cho^ng-up, Imshil, Namwon, Kwangju, Hampyong and Mokpo. The meteorological variable include relative humidity, evaporation, precipitation, air temperature, etc. As the result of this study, each climatic element showed the same aspects of change. During the summer, relative humidity, evaporation and precipitation, and air temperature reached their highest points, and wind speed, wind direction and diurnal temperature range fell to their lowest points, and the highest point appeared two times. The values of the climatic variables differed greatly among the different observatories. Integrated interpretation is also needed because there is more or less correlation among all the meteorological elements.

To explain quantitatively the statistical characteristics of typhoons on the south-western coastal areas of Korea, this paper mainly deals with the phenomena at Mogpo area. The sources of applied data chiefly are those of 'Typhoon report of Korea', 'Annual climatological report of Korea' (published by Korea central meteorological office) and 'Annual tropical cyclone report'(by J.T.W.C.). The quoted data are those observed during 86 years, from 1904 to 1989. The main contents are about the analysis of frequency, monthly distribution, location, track, intensity, accompanying wind, and arrival period. According to the analysis, the total number of the typhoons influencing the southwestern coastal area is 136 times. It comes under 5.5% of all. Monthly frequency centered on the months between July and September, 128 times which is 94% of all. Especially it occurred most often in August(57 times). Most of the typhoons occurred in 10∼20˚N and 125∼150˚E areas. The location of occurrence changed variously during a year. Generally occurred in lower latitudes and approached toward the northern areas. But it turned to the southern area again after September. It moved from the west to the east in the longitude. The track of typhoon drew the slow curve in earlier seasons, beginning in the westward of the lower latitude, and the quick curve in later seasons, beginning in the eastward of the higher latitude. The point of recurvature changed from the westward of lower latitude to the eastward of higher latitude and finally to the westward of lower latitude. The intensity of all the typhoons acting at Mogpo was under C class, often accompanied with over 80mm rainfall. The direction of winds is conspicuous in S direction series, but often N direction series appeared in May, June, and November. On the average it took 7 days for the typhoon to occurrence and arrive in Mogpo area.

柳贊洙 조선대학교 기초과학연구소 1985 自然科學硏究 Vol.8 No.1

This paper will show the numerical relation between all meteorological elements and meteorological factors. For this purpose, the multiple regression analysis is used, with the Computer (HB-3000) being utilized for precipitation, sea level and temperature measurements. On the results, it has been found that the multiple correlation coefficient of the total meteorological elements and meteorological factors is larger than the correlation coefficient of each meteorological element and factor, or the meteorological elements and factors' correlation coefficient. The numerical relation of the precipitation, sea level and temperature in this study area is expressed as follows; P=4.154+0.013H+0.892T.

Average maximum and minimum temperatures for the months of January and August in each year from 1940 to 1979 in the Kwang-Ju area revealed. The following overall trends: For the month of Jenuary, the maximum average temperature increased by 1.24℃ and the average temperature by 2.8℃; for the month of August, the average maximum increased by 0.23℃ and the average minimum by 0.26℃. In determining the relationship between maximum period of sun-spit activity and temperatures, it was found that in the three years leading to maximum activity there was an increasing in temperatures, whereas in the three years following maximum activity temperatures decreased by 0.33℃ per year. There was seem to be almost no influence of maximum and minimum sun-spot activity on temperature changes.

韓國 南西部 內陸 海岸 島嶼地域의 氣候要素 分布 및 變化

According to the classification of climate by Ko^‥ppen and McCune, the Korean peninsula belongs to the C (temperate) and D(polar) climatic divisions. This division is further divided into a local climatic area, thus the climate of the southwest inland area, seacoast and islands belong to CSW and CS climatic types. The climate of the northwest monsoon area which is affected bf the oceanic and the chinese continent climatic type is classified by the distribution of land and sea. For this study, two sites in the CSW and CS areas and the boundary area between the CSW and CS areas were selected, and the distribution of climatic elements were examined according to such weather data of the last ten year (1972 to 1981) as air temperature, amounts of precipitation and evaporation, relative humidity, duration of sunshine, wind speed and fog days. The air temperature showed a wide annua1 range in the order of Jeonju, Gwangju, Goheung, Mogpo, Yeosu and Wando, so the temperature was identical with the theoretical numbers. The precipitation was conspicuously high on island, showing a temperate type precipitation and large annual variation. It is a peculiar phenomenon that the coastal areas had the least annual mean precipitation. The humidity of Inlands, seacoast, and islands areas was similar to one another. The humidity in summer showed a high measurement, thus Indicating that the theoretical numbers were different from the actual measurements. The duration of sunshine in the selected sites was longest in May and August and shortest in June and July. and the duration on islands was longer than that of inlands. The amount of evaporation was similar to the duration of sunshine, so the amount was high in May and August, and low in December and January. The small amount of evaporation in June is connected with the duration of sunshine. It is a peculiar phenomenen that the amount of evaporation in Gwangju area was higher than that of the other areas. The wind speed in winter was higher than in summer, and the seacoast area's wind speed was particularly high. The fog days were very frequent in June and July in the coastal areas of Yeosu, Mogpo and Wando, and the other areas showed similar fog days all the year round. Especially, Yeosu showed conspicuously frequent annual mean fog days compared with the other areas.

The change of Climatic elements over a long period is functionally related. Among the climatic elements, air temperature and precipitation are the most important. In order to show the correlation between air temperature and precipitation, data over a 40-year-period (1941∼1980) were statistically analyzed, obtaining the following correlation equation : P=76.4T+180.5 (0.1mm, r=0.82) Gwangju's annual mean temperature is 12.9℃, its precipitation is 1280.8mm, its average precipitation days are 127, and 62.1% of the annual precipitation is concentrated in June, July, August and September. There are distinct periods of minimum precipitation (8.5 years), which occur during the period of Sunspot or one or two years defore or after the Sunspot period. The aridity index is 55.9 and coefficient of variation in precipitation is 2.34.

In an attempt to make oceanophysical observations of the coastal areas of Mogpo and Soheugsando 150km away from the southwestern coast, the periodical function formula of the surface-water temperature of the two areas was obtained by applying Fourier's processing theory and by examining and analyzing the records of the past 41 years in Mogpo and of the past 46 years in Soheugsando based on the original observation record of "Oceanographic data of the shore station." Variations of temperature were compared as well as the year-average surface temperatures and air temperatures. Their minimum value, minimum water temperature value, ten-days minimum value, and specific gravity were appeared to be low around Mogpo and the maximum value, yearly difference and daily variation appeared, on the reverse, to be high around Mpgpo. These facts are a energy reaches the earth. The conclusion is that since Mogpo is a coastal area with shallow water it has been greatly influenced by the radiation energy of the land specific heat.
