Major Oceanographic and Climatological Findings, Implications and Suggestions on the Central North Pacific Transition Zone

Abstract

The Central North Pacific Transition Zone (CNPTZ) is the continuation and intersection area of the western boundary intensified dynamic systems of high and low latitudes, an outstanding concentration area of large-scale, meso and small-scale ocean processes, and a key area for studying multi-scale thermodynamic processes of the ocean and air-sea coupled system, as well as the climate, environment and ecological effects. This paper reviews the scientific research achievements in relative regions of the CNPTZ from the perspective of oceanography and climatology, and puts forward research suggestions on associated scientific issues. The results show that the CNPTZ has important reference for understanding such as critical conditions, critical states, cross-border triggers, channel mechanisms of ocean and climate changes under the background of global warming. It is suggested to lead the joint marine survey in relevant regions through international cooperation, systematically build a climatic change observation system, develop interaction and cross feedback mechanism on multi-scale process and predictability research, create a bionic emulational multi-function coupling model, and break through the key technology of hazard and disaster risk projection and zoning, and thus to provide solid scientific and technological support for the deep understanding of ocean and climate changes, disaster prevention and mitigation, as well as regional marine governance and marine environment and ecological security.
