Abstract

Based on the NOAA climate datasets, trends, regional features, and possible causal relationships of interannual variations in water temperature on the surface (SST) and in the upper 750-meter layer of the subarctic Pacific with variations in the fields of air temperature, air pressure, wind, and climate indices over the past four decades are identified. The results revealed a degree of heterogeneity of the study region response to the ongoing global climate change, identified isolated areas, and quantified the warming rate in these areas. It is shown that in the west of the region, the SST trends are much higher than in the east, and in the warm season, they are about twice higher than in the cold season. Changes in water temperature and heat content anomalies in the water column of different regions are extremely uneven. The phases of alternating warm and cold periods are consistent with trends in the characteristics of the atmospheric centers of action, climate indices, and different climatic parameters.

亚北太平洋水温年际变化的区域特征

摘要

基于 NOAA 气候数据集、趋势、区域特征以及亚北极太平洋表面 (SST) 和上 750 米层水温年际变化与气温、空气确定了过去四年的压力、风和气候指数。结果揭示了研究区域对正在进行的全球气候变化的响应存在一定程度的异质性，确定了孤立的区域，并量化了这些区域的变暖率。结果表明，该地区西部海温变化趋势远高于东部，暖季比冷季高一倍左右。不同区域水体水温变化和热含量异常极不均匀。
