Characteristics of the large-height swell-like waves on the east coast of Korea

Abstract

The reason for appearance of the high swell-like waves was found to be due to the long-lasting strong northeasters in the East Sea, which was formed as a result of the low pressure trough in the vicinity of the extra-tropical low pressure system that advances to East Sea from the China inland with decreasing its central pressure. Such a strong low pressure system can be occasionally developed in winter season and may cause severe disaster repeatedly on the coast of Korea. In this respect, it is required to further enhance predictability of the high swell-like waves, based on understanding of the detailed mechanism of the rapid growth of the low pressure system.re system that advances to East Sea from the China inland with decreasing its central pressure.
