项目摘要

The sea off Sanriku Coast is known as complicated oceanic conditions, which is formed by the Kuroshio and Oyashio currents and many warm-core rings. Because of this feature, it is sometime called as confluence zone. Since good commercial fish grounds are formed, this sea area is important for the Japanese fisheries. The purpose of present study was to develop a prototype system for forecasting of the short-term variations relating to the warm-core rings.First, we reprocessed the NOAA-A VHRR data locally received at the Tohoku University for generation of 4-6 sea surface temperature images in a day. Through investigation of these images, we picked up 92 events of the short-term variations. Foe all of these events, we conducted simulation experiments using the contour dynamics model, which shows good performance for each event. The warm-core rings propagate from the eastern ocean into the study area, and its number density becomes high. One of the factors which activate the short-term variations in the study area is the interaction of the warm-core rings with the high-number density.We analyzed the altimeter sea-surface height together with the high-resolution Sea Surface Temperature images, and developed methodology to estimate the sea surface height and surface velocity around the warm-core rings. Throughout this study, a basic system is established to predict the positions of SST fronts, which shows the locations of warm-core rings, using the satellite altimeter and SST measurements as the initial conditions.
三陆沿岸海域是由黑潮和亲潮海流以及许多暖核环组成的复杂海洋环境。由于这一特点,它有时被称为汇合区。由于形成了良好的商业渔场,这片海域对日本渔业很重要。本研究的目的是开发一个原型系统,用于预测短期变化的暖心环。首先,我们重新处理的NOAA-A VHRR数据在本地接收的东北大学在一天内生成4-6海表温度图像。通过对这些图像的研究,我们提取了92个短期变化事件。对于所有这些事件,我们进行了模拟实验,使用轮廓动力学模型,它显示了良好的性能,为每一个事件。暖心环从东大洋向研究区传播,其数密度变高。通过对高分辨率海表温度和高度计海表高度的分析,提出了估算暖核环附近海表高度和表面速度的方法。在整个研究中,建立了一个基本的系统来预测SST锋的位置,它显示了暖心环的位置,使用卫星高度计和SST测量作为初始条件。
