在一个理想化的海洋环流模式(GCM)中,研究了由于海洋初始条件和模式参数化误差而引起的纬向翻转环流(MOC)和上层海洋温度的可预报性极限。使用GCM、其切线性和伴随模型计算奇异向量(最佳扰动),以确定北大西洋气候可预测性的上限。
The limits of predictability of the meridional overturning circulation (MOC) and upper‐ocean temperatures due to errors in ocean initial conditions and model parametrizations are investigated in an idealized configuration of an ocean general circulation model (GCM). Singular vectors (optimal perturbations) are calculated using the GCM, its tangent linear and adjoint models to determine an upper bound on the predictability of North Atlantic climate.
