Tsunami / sea condition monitoring and prediction device

摘要

PURPOSE: To achieve a planar and quasi-real-time maritime weather observation and to achieve an effective monitoring of maritime weather abnormality and a reliable monitoring prediction of tidal wave utilizing planar data. CONSTITUTION: A monitoring prediction device is provided with two radar devices 1A and 1B for observing a level distribution in a sea surface flow application direction in a monitoring sea area and the flat-surface distribution of wave characteristics and monitoring devices 2-6 for monitoring and predicting the presence or absence of tidal waves, the characteristics of tidal wave, and the arrival time of the tidal wave by synthesizing each plane distribution data observed by the two radar devices 1A and 1B and using the prediction pattern of tidal current, drift current, and coastal current and tidal wave arrival information and for monitoring the abnormal maritime weather using the prediction pattern of maritime weather including wave characteristics. Then, after obtaining the plane distribution of sea surface flow by performing the spectrum synthesis of the plane distribution in sea level flow application direction observed by two radar devices 1A and 1B, the abnormal plane distribution of the sea surface flow is obtained according to the difference with the prediction pattern of current, drift current, and coastal current and flow rate deviation analysis is performed to obtain the abnormal deviation distribution of a sea level flow.
