在年际到十年的时间尺度上，模型模拟表明，在北大西洋的深水形成率，副极地环流的强度和纬向翻转环流的异常之间有很强的关系。这是否有效，只能通过连续的、长期的观测时间序列来证实。几个测量组件已经到位，但关键的阵列，以获得时间序列的纬向体积和热量输送在副极地北大西洋仍然失踪。本文综述了近年来有关深水形成率和副极地环流输运的研究进展。我们讨论了如何在副极地北大西洋现有的观测组件可以补充，以提供长期监测的纬向热量和体积运输。通过对观测和模式结果的综合分析，讨论了必须用仪器覆盖的时间和空间尺度，以及速度和温度场变化最大的关键区域。(C)2011爱思唯尔有限公司保留所有权利。
On interannual to decadal times scales, model simulations suggest a strong relationship between anomalies in the deep water formation rate, the strength of the subpolar gyre, and the meridional overturning circulation in the North Atlantic. Whether this is valid, can only be confirmed by continuous, long observational time series. Several measurement components are already in place, but crucial arrays to obtain time series of the meridional volume and heat transport in the subpolar North Atlantic are still missing. Here we summarize the recent developments of the deep water formation rates and the subpolar gyre transports. We discuss how existing observational components in the subpolar North Atlantic could be supplemented to provide long-term monitoring of the meridional heat and volume transport. Through a combined analysis of observations and model results the temporal and spatial scales that had to be covered with instruments are discussed, together with the key regions with the highest variability in the velocity and temperature fields.
