초록
Representative tidal gauging (TG) stations are selected to cover the tidal characteristics of the Korean peninsula coastal seas, and the statistical parameters of the data are analysed from the perspective of the probabilitydistribution at that TG station. The shape of the distribution in the Incheon and Gunsan TG stations, which are tidedominatedareas, shows two clear modes at HWONT and LWONT in the distributions, and in the Mokpo station,shows an asymmetric double peak distribution. In contrast, the frequency distribution shape shows a smoothed flatpeak in the Jeju, Yeosu and Busan TG stations, and a single peak in the Pohang and Sokcho TG stations. Theemersion and submersion equations suggested as the 6-parameter Gaussian mixture models in this study areaccurate, and well fitted to the observed tidal elevation data. The μ1, μ2 parameters are highly correlated to theLWONT and HWONT, and the σ1 and σ2 parameters are also closely correlated to the mean tidal range. The μ1 andμ2 parameters coincide with the modes of the suggested probability distribution of the hourly tidal level data.
Abstract
Representative tidal gauging (TG) stations are selected to cover the tidal characteristics of the Korean peninsula coastal seas, and the statistical parameters of the data are analysed from the perspective of the probabilitydistribution at that TG station. The shape of the distribution in the Incheon and Gunsan TG stations, which are tidedominatedareas, shows two clear modes at HWONT and LWONT in the distributions, and in the Mokpo station,shows an asymmetric double peak distribution. In contrast, the frequency distribution shape shows a smoothed flatpeak in the Jeju, Yeosu and Busan TG stations, and a single peak in the Pohang and Sokcho TG stations. Theemersion and submersion equations suggested as the 6-parameter Gaussian mixture models in this study areaccurate, and well fitted to the observed tidal elevation data. The μ1, μ2 parameters are highly correlated to theLWONT and HWONT, and the σ1 and σ2 parameters are also closely correlated to the mean tidal range. The μ1 andμ2 parameters coincide with the modes of the suggested probability distribution of the hourly tidal level data.
