Response of the Equatorial Basin‐wide SST to Non‐breaking Surface Wave‐induced Mixing in a Climate Model: An Amendment to Tropical Bias
摘要
Tropical biases, such as the cold tongue bias in the Pacific and the warm bias in the Atlantic, are persistent problems in coupled climate models. This paper investigates the impact of including non-breaking wave-induced vertical mixing (Bv) in the CCSM3 model. The inclusion of Bv deepens the ocean mixed layer and warms the subsurface, which improves the simulation of the equatorial thermocline. Consequently, the cold bias in the equatorial Pacific and the warm bias in the eastern currents are alleviated. The mechanism involves the rectification of the vertical heat transport, demonstrating that wave mixing is a crucial physical process for realistic climate simulations.
