Since Late Proterozoic era, the Korean Peninsula has been evolved into a state with relatively stable regions and orogenic beltswhich were developed differently each other. The Late Paleozoic (Late Carboniferous－Early Triassic) sediments are well developed in the Korean Peninsula, and called the Pyongan System. The Pyongan System from Late Carboniferous to Lower Triassic is distributed in the Pyongnan and Hyesan-Riwon Basins, and Rangrim Massif, and divided into Hongjom (C2 ) , Ripsok (C2 ) , Sadong (C2-P1 ) , Kobangsan and Rokam ( Taezhawon) ( P2-T1 ) sequences. The sediments of the Tumangang Orogenic Belt are called Tuman System which is composed of the Amgi Series, consisting of clastic formation with mafic effusive material, overlaid by the Kyeryongsan Series, consisting mainly of mafic volcano sediments. The Songsang Series which rests on the Kyeryongsan Series mainly consists of clastic formation with minor felsic effusive material. In the Tuman- gang Orogenic Belt the tectonic movement, called Tumangang Tectonic Movement, occurred in the Lower Permian－Lower Triassic.  相似文献

韩国济洲岛下西归浦组的时代归属一直存在着争论。该段地层中浮游有孔虫 Globigerina calida calida、Beella digitata、 Globigerina bermudezi和 Globoquadrina conglomerata的发现表明了它应为中更新世 (晚 N 2 2带、即 Globigerina calida calida亚带 ,不晚于 40万年前 )的沉积。底栖、浮游有孔虫的定量统计分析揭示了下西归浦组沉积环境的变化 :下部的沉积环境为岸外中陆架暖水 ,而向上则演变成近岸内陆架温凉水。有孔虫组合的更替反映了下西归浦组沉积是一个由次一级的 3个亚海退和 2个亚海进组成的海退序列。  相似文献   

Spatio-temporal variability in sea surface wind stress near and off the east coast of Korea   总被引：1，自引：1，他引：0

Sea surface wind stress variabilities near and off the east coast of Korea, are examined using 7 kinds of wind datasets from measurements at 2 coastal (land) stations and 2 ocean buoys,satellite scatterometer (QuikSCAT), and global reanalyzed products (ECMWF,NOGAPS,and NCEP/NCAR). Temporal variabilities are analyzed at 3 frequency bands; synoptic (2-20 d), intra-seasonal (20-90 d),and seasonal (>90 d).Synoptic and intra-seasonal  相似文献   

Long-term variability of cold surges in Korea     

Kwang-Yul Kim  Seoyeon Lee  Maeng-Ki Kim  Chun-Ho Cho 《Asia-Pacific Journal of Atmospheric Sciences》2014,50(4):519-529

Cold surge statistics have been analyzed from the 52-year (1961–2012) winter temperature data archived at Korea Meteorological Administration. Despite a significant winter warming in South Korea, there is no statistically affirmable sign of the occurrence frequency, duration and total days of cold surges to have changed in the record; there is little abatement in the frequency, duration, and total days of cold surges. Thermal advection anomalies were also derived from the NCEP/NCAR and ERA interim reanalysis datasets. Cold surges defined in terms of thermal advection anomalies do not exhibit any statistically significant change either. The increased mean and the decreased variance of thermal advection both indicate that cold advection from north has, in fact, decreased gradually in South Korea. It appears that cold surges are statistically rare enough to be affected by increased mean and decreased variance of thermal advection. Polar warming is often interpreted as weakening of jet stream and increasing southward flux of cold air. Analysis of thermal advection, on the other hand, does not show increased advection of cold air from north in South Korea.  相似文献   

The impact of cumulus parameterizations and microphysics schemes under different combinations on typhoon track prediction   总被引：2，自引：1，他引：1

This study examines the effects of cumulus parameterizations and microphysics schemes on the track forecast of typhoon Nabi using the Weather Research Forecast model. The study found that the effects of cumulus parameterizations on typhoon track forecast were comparatively strong and the typhoon track forecast of Kain-Fritsch (KF) was superior to that of Betts-Miller (BM). When KF was selected, the simulated results would be improved if microphysics schemes were selected than otherwise. The results from Ferrier, WSM6, and Lin were very close to those in the best track. KF performed well with the simulations of the western extension and eastern contraction changes of a North Pacific high as well as the distribution and strength of the typhoon wind field.  相似文献   

Fault tectonic analysis of Kii peninsula,Southwest Japan: Preliminary approach to Neogene paleostress sequence near the Nankai subduction zone     

POM‐YONG CHOI  SATOSHI NAKAE  HYEONCHEOL KIM 《Island Arc》2011,20(4):455-476

The southern part of the Outer Zone of Southwest Japan including the Kii peninsula belongs to the tectonic ‘shadow zone’, where fewer conspicuous active faults and less Quaternary sediments develop than in the Nankai subduction zone and Inner Zone of Southwest Japan. In order to study the paleostress sequence of the Kii peninsula, we analyzed fault‐slip data and tension gashes at pilot sites of Early–Middle Miocene forearc sediments and Late Cretaceous accretionary complex. According to the results, six faulting events are reconstructed in sequence: (i) east–west extension (normal faulting); (ii) east–west compression and north–south extension (strike‐slip faulting); (iii) NNW–SSE compression and ENE–WSW extension (strike‐slip faulting); (iv) northeast–southwest compression and northwest–southeast extension (strike‐slip faulting); (v) WNW–ESE compression (strike‐slip or reverse faulting); and (vi) NNE–SSW extension. The north–south to NNW–SSE trending dyke swarm of Middle Miocene age in the Kii peninsula is thought to be related to Event 3, implying that Event 3 was active at least during the Middle Miocene. Because Event 6 is recognized solely at a site, the overall latest faulting event seems to be Event 5. Assuming that the compression results from the motion of the crust or plate, the compression direction of Event 5 is in good accordance with the present‐day WNW crustal velocity vectors of the Kii peninsula. The stress trajectory map of Southeast Korea and Southwest Japan reveals that the current compression directions of the Kii peninsula correspond to the combinatory stress fields of the Himalayan and Philippine Sea tectonic domains.  相似文献
