项目摘要
Research Institute for Applied Mechanics, Kyushu University has been monitoring the current structures on the vertical section along the cruise line of a regular ferryboat (Camellia) between Hakata and Pusan using ADCP(Acoustic Doppler Current Profiler) mounted to the ferryboat since February in 1997. The ferryboat made round trips three times a week until February in 2004 and the new ship introduced from July in 2004 makes six times a week. Observed data were recovered once a month before the middle of 2001 from the beginning. However, the newly introduced real time data transferring system using telephone network by this scientific research fund made possible almost real time monitoring of the Tsushima current. Data were recovered three times a week until February in 2004 from the middle of 2001 and six times a week since the introduction of new ship in July in 2004. Those data were used for the research of the Japan Sea circulation and the prediction system of the Japan Sea as boundary conditions. Parts of these data are also accessible through our web page(http://nmg.riam.kyushu-u.ac.jp/~camellia/).Those data clarified many aspects of the Tsushima Current such as the current structure and volume transport, and those seasonal and inter annual variabilities. An empirical equation was proposed to estimate the volume transport of the Tsushima Current using sea level differences between Hakata, Izuhara and Pusan. This equation makes also possible the estimation of past change of volume transport as long as sea level data were obtained. In addition, one hour interval of sea level data made a great progress in the study of short term(a couple of days) variabilities which are greatly attributed to non-isostatic response of the Japan Sea to atmospheric pressure disturbances with energy peak at 3-5 days.
九州大学应用力学研究所自1997年2月以来一直使用安装在渡轮上的ADCP(声学多普勒水流剖面仪)监测博田至釜山之间一艘常规渡轮(山茶花)邮轮沿线垂直部分的水流结构。直到2004年2月,渡轮每周往返三次,从2004年7月开始推出的新船每周往返六次。观测数据从开始到2001年年中之前每月恢复一次。然而,该科研基金新引入的利用电话网络进行实时数据传输的系统,使对马流几乎可以实时监测成为可能。从2001年年中到2004年2月,每周恢复三次数据,自2004年7月引入新船以来,每周恢复六次。这些资料被用作研究日本海环流和日本海预报系统的边界条件。这些数据的一部分也可以通过我们的网络获取,page(http://nmg.riam.kyushu-u.ac.jp/~camellia/).Those数据阐明了对马流的许多方面,如当前的结构和体积输送,以及那些季节和年际变化。提出了利用博田、井原和釜山之间的海平面差来估算对马流的流量输送的经验公式。只要获得海平面数据,这个方程就可以估计过去运量的变化。此外,1小时间隔的海平面资料在研究短期(几天)变化方面取得了很大进展,这主要归因于日本海对大气压力扰动的非均衡响应,能量峰值在3-5天。
