Abstract

The present work intends to hindcast tidal conditions at Naval Battle of Noryang on 16th of December 1598. The works involves in calendar day conversion and tidal prediction in several centuries ago. Conversion between lunar calendar day and solar calendar day before 1900 was taken from KASI (http://astro.kasi.re.kr/Life/ConvertSolarLunarForm.aspx?MenuID=115). Among three victorious naval battles (Hansan battle on 14 August 1592, Myungryang battle on 25 October 1597 and this Norayang battle) led by Admiral Yi, we first attempt to reproduce tidal conditions during the last battle of Admiral at Noryang to set up the regional tidal hindcast of old times both by point and by numerical model simulation.We have set up Delphi based GUI tidal analysis and prediction system, MARI.E which works in Gregorian dates, and using harmonic constants derived at Yeosu (Yeosu2002.HG). A lot of information for Julian and Gregorian Calendar are exist (http://www.fourmilab.ch/documents/calendar). The Julian Calendar started in 45BC and Pope Gregory implemented the Gregorian Calendar in 1582. We hindcasted 1598 tides using MARI.E at Yeosu (Yeosu1598.PRE) for model verification. These conversions are used for MARI.E and also specifying open boundary conditions of our FEM based ROTIS (regional ocean tide simulation) for the Yellow and East China Seas. Some of preliminary results for model verification and tidal currents hindcasted at Kwand solar calendar day before 1900 was taken from KASI (http://astro.kasi.re.kr/Life/ConvertSolarLunarForm.aspx?MenuID=115).
