Studies on monitoring of marginal sea using satellite and monitoring of the Kuroshio variation

2002年进行的研究如下。(1)We（2）准备了2000年9月和10月的逐日无云海表温度资料，并将其用于数值模式的预报。该数据集存档在记录当前研究结果的CD-ROM中。（3）在与日本海洋科学技术中心的合作研究下，利用定期往返于东京和小笠原群岛的渡船，进行了为期一年的ADCP监测。（4）利用宫城县教育委员会所属的“宫城丸”号训练船，在夏威夷与日本之间进行了每年3次的高密度XBT监测。使用这些数据与PX-37数据，我们估计热量和淡水运输通过这些线。(5)We利用TOPEX POSEIDEON高度计资料，研究了中尺度涡旋与黑潮路径变化之间的相互作用。结果表明，黑潮的小弯曲是涡旋与黑潮的碰撞造成的。（6）对XBT数据的详细分析表明，日本的几台XBT变流器都出现了所谓的“弓弯现象”。同时还发现，XBT测量系统的瞬态响应使海面至4 m的XBT数据受到影响。

Studies made in 2002 are as follows. (1)We investigated the spatio-temporal correlation analyses for the sea surface temperature (SST) data free from clouds, and we also developed the advanced method generating new generation SST(2)We prepared the daily and cloud-free SST dataset for September and October 2000, which was used in the numerical model for prediction. This dataset was archived in the CD-ROM recording the present study results.(3)Under the cooperative study with Japan Marine Science and Technology Center, we made ADCP monitoring through a year by a ferry regularly shuttling between Tokyo and Ogasawara Islands.(4)Using the training vessel, "Miyagi-Maru" belonging to Miyagi Prefectural Education Committee, we made high density XBT monitoring three times a year between Hawaii and Japan. Using these data together with the PX-37 data, we estimated heat and freshwater transports crossing these lines.(5)We investigated an interaction between mesoscale eddies and the Kuroshio path variation using TOPEX POSEIDEON altimeter data. It was found that the collision of eddy to the Kuroshio caused the small meander of the Kuroshio.(6)Detailed analyses of the XBT data showed that several Japanese XBT converters were suffered from so-called "Bowing phenomenon". It was also found that the XBT data from the sea surface to 4m were suffered from the transient response of the XBT measurement system.
