文勝義,水縝 부산대학교 과학교육연구소 1979 교사교육연구 Vol.6 No.2
The annual and monthly precipitations in Pusan area for 1904-1974 were classified into five anomaly, levels and were analyzed statistically to know the frequency distribution and its characteristcs of each anomaly level. The results of this study are as follows: 1) The maximum frequency of anomaly levels occurs on LN-level and a level is not denoted higher or lower than S-lvel or GA-level in the annual precipitation. 2) In the monthly precipitations, there are no EA-levels in January, March, June, July, September, December and no MEA-levels except in January, February, June, and October.

The characteristics on the transtion probabilities and periodicity for the daily precipitation occurrence in Korean peninsula are investigated by applying the Markov chain properties to daily precipitation occurrence. In order to examine the responses of Markov Chain properties to the applied period and their magnitudes, three cases (Case A: 1956∼1985 at 14 stations, Case B: 1965∼1994 at 14 stations, and Case C: 1985∼1994 at 63 stations) are considered in this study. The transition probabilities from wet day to wet day for all cases are about 0.50 and in summer, especially July, are higher. In addition, considering them in each station we can find that they are the highest at Ullung-do and lowest at Inchon for all cases. The annual equilibrium probabilities of a wet day appear 0.31 in Case A, 0.30 Case B, and 0.29 Case C, respectively. This may explain that as the data-period used becomes shorter, the higher the equilibrium probability is. The seasonal distributions of equilibrium probabilities are appeared the lowest(0.23∼0.28) in winter and the highest(more than 0.39) in spring and monthly in July and in October, repectively. The annual mean wet duration for all cases is 2.04 days in Case A, 1.99 Case B, and 1.89 Case C, repectively. The weather cycle obtained from the annual mean wet and dry duration is 6.54∼6.59 days, which are closely associated with the movement of synoptic systems. And the statistical tests show that the transitions of daily precipitation occurrence for all cases may have two-state first Markov chain property, being the stationarity in time and heterogeneity in space.

The main purpose of this study is to clarify the difference of surface air climatology between the east and west coasts of the Korean Peninsula using the surface climatic elements. It was clarified that some climatic elements (precipitation, temperatures, rainy day, vapor pressure, relative humidity, surface air pressure) except diurnal range of temperature and wind speed show considerable difference between the east and west coasts of the Korean Peninsula. It was examined synoptically the reason which concern the regional difference. The effect of monsoon, adding the effect of Jangma front in summer produce the difference of surface air climatology between the east and west coasts of the Koreane Peninsula. Seasonal change of the surface climate along the east and west coasts of the Korean Peninsula was also dealt in this study.

There are f reezing phenonena in summer at so called "Ice-valley" in the south-eastern part of the Korean peninsula. The purpose of this paper is to examine the causes of this ice-forming phenomena which can be explained by following causes. (1) As the valley is very deep and is toward the North, the insolations to the "Ice-valley" are very little through the year. Therefore, the under ground (15m from the surface) temperatures maintain about 6°C in summer. (2) The upper capillary zone is considered as a adiabatic situation because this zone is insulated from the solar radiation by the Talus having very large boulders(50-20G<* in dia.) (3) As the defferences of saturated vapor pressure between upper capillary zone and outside of the Talus are very high, the evaporization will be occur on the upper capillary zone. (4) Consequently, water is frozen by the loss of evaporization heat due to the evaporation at the upper capillary zone.

Through the comparison of old and new high school earth science curriculum, we can draw the following results about structualization of the new high school earth science curriculum. 1) It shows a change of displine centered to humanistic centered curriculum in new ones. 2) By deviding the earth science curriculum into Ⅰand Ⅱ, more over being taken course of them in all high school, the importance of education of earth science is more emphasized. 3) The reason why the structure is considered importantly in Ecucation is to enhance the efficiency of understanding the subject, planning of curriculum, selection of basic knowledge, understanding of discipline, and teaching. 4) For this kind of strutualization, mode of structualization and selection of basic elements of content are required. Major modes of structualion are: method by mode of representation, method by substantive structure and syntactival structure, and method by hierarchical order. The basic element of content for structualization selected at the levels of the following criteria: ideas and themes, rules of principles, basic concepts and factual knowledge.

The abnormal cold waves of 1976-77 winter which caused lots of damages to overall of the Korean Peninsula were analyzed statistically and synoptically using the temperature data (1904-77) at Busan Station. The statistical results of this cold waves are summarized as follows: 1. The average temperature of January 1977 is -1.0℃, the rank is the 5th. The average minimum temperature of January 1977 is -4.5℃, the rank is only the 7th. 2. The number of successive cold days of this cold waves, namely, the number of days which lasted successively below 0℃ in daily average temperature, was the longest one (a total of 30 days) since 1905. The number of days which lasted below -5.0℃ in the average minimum temperature was also the longest one (20 days). 3. The temperature oscillation of more than 20.0℃ was respectively onetime in other cold years, on the other hand, 4 times in this winter, and the most marked oscillation was 27.2℃ in 3 days (February, 13-16, 1977). The results of synoptic analysis are as follows: 1. The influence of Siberian High during this cold period was greater than that of any other years, and also Aleutian Low was developed intensively, so thewest-high and east-low pressure system lasted for a ling time. 2. The pressure distribution of the upper level was similar to that of 1963 which resembles Baur Model C. So, the upper level temperature was very cold. The cause of this record-breaking cold waves was regarded as the southward movement of cold vortex from the Arctic region to the middle latitudes.

We have attempted to estimate short period flood warning at Hweonpung in the mid-Nagdong river area, on the basis of the correlations between average area precipitation of catchment area of upstream of Hyeonpung and the precipitation and the discharge, and the water level at Hyeonpung. Furthermore, the period of annual maximum overflow level has been analysed. The results are as follows : 1) The correlation of June and August between the average area precipitation" of catchment area of upstream of Hyeonpung and the water level at Hyeonpung shows “moderate connection" with the highest value in August. 2) The correlation between the average area precipitation of upstream1 catchment area of Hyeonpung and the precipitation at Hyeonpung lies in ^intimate connection”. 3) It is-asumed that we can forecast the water level at Hyeonpung immediately from the precipitation at Hyeonpung-according to the results of 1) and 2). 4) Because of low correlation between average area precipitation of upstream catchment area of Hyeonpung and the discharge at Hyeonpung, it hardly seems to help forcast short period flood warning. 5) Finally, we have come to know that the period of annual maximum overflow' level is about 11-12 years.

The purpose of this study is to analyze synoptically some characteristics of the surface inversion at Kori, southeastern part of Korea and to be useful for a searching examination of the air pollution potenial at a coastal industrial region. The data used in this study are the temperatures at 20m and 1.5m above the surface, wind velocity and wind direction observed hourly at the monitoring station which is located at Gilcheon-ri (N35˚19'44", E129˚17'20") near Kori in Korea, from December, 1967 to November, 1970. By analyzing these data statistically and synoptically, the following results were acquired. 1) The occurence frequency of the surface inversion is the highest in November and the lowest in June. In seasonal variation, autumn has the highest and summer has the lowest occurrence frequency. 2) The modes of the onset and dispersion times of the surface inversion are 18:00 and 08:00 respectively. The annual mean duration of the surface inversion is 11.3 hours. 3) The aspects of annual variations of inversion intensity and occurrence frequency with time are similar to each other and also have a close connection with sunrise, sunset and the changing time of land and sea breezes. 4) According to Pasquill's stabillity classification in inversion cases, it was proved that there are the classes of E, F and G being stable in inversion cases at Kori.
