摘要

摘要利用INM-RAS气候模型的理想化数值实验研究了北冰洋上层300米温度的潜在可预测性。研究表明,热含量可以预测长达4-6年。在温度和盐度出现正异常之前的几年里,大西洋流入北冰洋的水量超过了平均值。表面场,包括温度、盐度、冰的浓度和质量,比0-300米层的热含量更不可预测。

On the multi-annual potential predictability of the Arctic Ocean climate state in the INM RAS climate model
Abstract Idealized numerical experiments with the INM RAS climate model are used to study the potential predictability of the temperature in the upper 300-meter layer of the Arctic Ocean. It is shown that the heat content can be predictable for up to 4–6 years. Positive anomalies of the temperature and salinity are preceded for several years by a state in which the influx of Atlantic water into the Arctic Ocean exceeds the average value. Surface fields, including temperature, salinity, concentration and mass of ice, are less predictable than the heat content in the layer of 0–300 meters.
