“…Furthermore, the study focuses on ocean response, and has not investigated the atmospheric response to the coupling. The atmospheric response to fronts and eddies has been an area of rich studies in many regions, such as the Aughlas current [21] , the Gulf Stream [24] , the eastern Equatorial Pacific [8] , and so on. The global atmospheric response to the scheme will be explored in the future.…”

“…The sea surface temperature (SST) frontal influences on surface winds and wind stress at oceanic mesoscale have been well documented [1][2][3][4][5][6][7][8][9][10] . Satellite scatterometer measurements, in-situ observations and numerical models all reveal that surface wind is higher over warm water and lower over cold water near a SST front.…”

A simple temperature-dependent wind stress scheme is implemented in National Center for Atmospheric Research (NCAR) Community Earth System Model (CESM), aiming to enhance positive wind stress and sea surface temperature (SST) correlation in SST-frontal regions. A series of three-year coupled experiments are conducted to determine a proper coupling coefficient for the scheme based on the agreement of surface wind stress and SST at oceanic mesoscale between model simulations and observations. Afterwards, 80-year simulations with/without the scheme are conducted to explore its effects on simulated ocean states and variability. The results show that the new scheme indeed improves the positive correlation between SST and wind stress magnitude near the large oceanic fronts. With more realistic surface heat flux and wind stress, the global SST biases are reduced. The global ocean circulation represented by barotropic stream function exhibits a weakened gyre circulation close to the western boundary separation, in agreement with previous studies. The simulation of equatorial Pacific current system is improved as well. The overestimated El Niño Southern Oscillation (ENSO) magnitude in original CESM is reduced by ~30% after using the new scheme with an improved period.

“…Previous studies found that wind stress is modified over regions with large SST gradients (e.g., Chelton et al, 2004;Chelton & Xie, 2010;K.-A. Park et al, 2006;Small et al, 2008;R.-H. Zhang et al, 2014). Due to the low resolution in current POP2, SST fronts simulated will be smoothed out, and thus, the effect of SST gradient on wind stress might be underestimated.…”

A team effort to develop a Community Integrated Earth System Model (CIESM) was initiated in China in 2012. The model was based on NCAR Community Earth System Model (Version 1.2.1) with several novel developments and modifications aimed to overcome some persistent systematic biases, such as the double Intertropical Convergence Zone problem and underestimated marine boundary layer clouds. Aerosols' direct and indirect effects are prescribed using the MACv2‐SP approach and data sets. The spin‐up of a 500‐year preindustrial simulation and three historical simulations are described and evaluated. Prominent improvements include alleviated double Intertropical Convergence Zone problem, increased marine boundary layer clouds, and better El Niño Southern Oscillation amplitude and periods. One deficiency of the model is the significantly underestimated Arctic and Antarctic sea ice in warm seasons. The historical warming is about 0.55 °C greater than observations toward 2014. CIESM has an equilibrium climate sensitivity of 5.67 K, mainly resulted from increased positive shortwave cloud feedback. Our efforts on porting and redesigning CIESM for the heterogeneous Sunway TaihuLight supercomputer are also introduced, including some ongoing developments toward a future version of the model.
