Abstract

The results of assessing long–term changes in water temperature in the northern part of the Atlantic Ocean (0°–70° N, 8°–80° W) according to the data of ocean reanalyses and objective analyses for the periods of 1961–2011 and 1980–2011 are presented. The obtained estimates are based on the use of a nonparametric method of regression analysis (quantile regression) for the monthly mean ocean temperature for a quantile value of 0.5. In 1961–2011 the warming was mainly recorded in the upper 400-m layer in the region from the equator to 70° N. Over this 51-year period, the increase in the median monthly ocean temperature was ~0.5°C on average in the analyzed water area, while in the Gulf Stream–North Atlantic Current system, it was ~1°C. During the period of 1980–2011, the warming in the northern part of the Atlantic Ocean occurred mainly in the upper 1-km layer at high latitudes (50°–65° N). Over this 32-year period, the median monthly mean ocean temperature increased in the subpolar gyre in the upper 400-m layer by ~1°C.

根据海洋再分析数据，大西洋北部水温变化的长期趋势

摘要

根据1961-1961年期间海洋再分析和客观分析数据，评估大西洋北部（北纬0°–70°，西经8°–80°）水温长期变化的结果介绍了 2011 年和 1980-2011 年。获得的估计值基于对分位数值为 0.5 的月平均海洋温度使用非参数回归分析方法（分位数回归）。 1961年至2011年，变暖主要发生在赤道至北纬70°区域的上400米层。在这51年期间，月平均海洋温度升高约0.5°C。分析水域，而在墨西哥湾流-北大西洋洋流系统中，温度约为 1°C。 1980—2011年期间，大西洋北部变暖主要发生在高纬度（50°—65°N）上1公里层。在这 32 年期间，上 400 米层副极地环流的月平均海洋温度中值增加了约 1°C。
