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

2002年的研究结果如下：(1)研究了无云海表温度的时空相关分析，并提出了生成新一代海表温度的先进方法。(2)制备了2000年9月和10月的日海表温度和无云海表温度数据集，并将其用于数值模式预测。该数据集存档在记录本研究结果的CD-ROM中。(3)在与日本海洋科学技术中心的合作研究中，我们通过定期往返于东京和小笠原群岛之间的轮渡进行了为期一年的ADCP监测。(4)利用宫城县教育委员会所属的“宫城丸”号训练船，每年三次在夏威夷和日本之间进行高密度XBT监测。利用这些数据和PX-37数据，我们估计了穿越这些线的热量和淡水输送。(5)利用TOPEX POSEIDEON高度计资料研究了中尺度涡旋与黑潮路径变化的相互作用。研究发现，涡旋与黑潮的碰撞导致了黑潮的小曲流。(6)对XBT数据的详细分析表明，日本的几台XBT转换器存在所谓的“弯曲现象”。从海面到4m的XBT数据受到XBT测量系统的瞬态响应的影响。

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.
