| Outline of Final Research Achievements |
Submesoscale disturbances on the scale of several kilometers to several tens of kilometers play an important role in the energy cascade and the material transport in the ocean. As a foundation for investigating the wide-area distribution of submesoscale disturbances, a method to detect submesoscale disturbance by using temperature/salinity intrusion structure from the vertical profile data of Argo profiling float array deployed over the global ocean.
In order to understand the process to form a high vertical wave number structure associated with the development of submesoscale phenomena, unique intensive shipboard observation was carried out in the east coast of Honshu, enabling us to grasp this process directly and in detail. This observation quantitatively and theoretically supported the above identification method.
