| 英文摘要 | Solar radiation penetration in the upper ocean is strongly modulated by phytoplankton, which impacts the upper ocean temperature structure, especially in the regions abundant with phytoplankton. in the paper, a new solar radiation penetration scheme, based on the concentration of chlorophyll-a, was introduced into the lasg/iap (state key laboratory of numerical modeling for atmospheric sciences and geophysical fluid dynamics/institute of atmospheric physics) climate system ocean model (licom). by comparing the simulations using this new scheme with those using the old scheme that included the constant e-folding attenuation depths in licom, it was found that the sea surface temperature (sst) and circulation in the central and eastern equatorial pacific were both sensitive to the amount of phytoplankton present. distinct from other regions, the increase of chlorophyll-a concentration would lead to sst decrease in the central and eastern equatorial pacific. the higher chlorophyll-a concentration at the equator in comparison to the off-equator regions can enlarge the subsurface temperature gradient, which in turn strengthens the upper current near the equator and induces an enhancing upwelling. the enhancing upwelling can then lead to a decrease in the sst in the central and eastern equatorial pacific. the results of these two sensitive experiments testify to the fact that the meridional gradient in the chlorophyll-a concentration can result in an enhancement in the upper current and a decrease in the sst, along with the observation that a high chlorophyll-a concentration at the equator is one of the predominant reasons leading to a decrease in the sst. this study points out that these results can be qualitatively different simply because of the choice of the solar radiation penetration schemes for comparison. this can help explain previously reported contradictory conclusions. |
