What are the climate effects on the planet and the atmosphere as the Southern Ocean warms? When will Southern Ocean carbon uptake decrease due to warming?
The Southern Ocean has warmed significantly and is projected to warm further during the 21st century and beyond, with far-reaching consequences. Until now, Antarctic stratospheric ozone
The reduction and increase of atmospheric CO2 has intensified the warming of the southern oceans. Despite the projected improvement in ozone, further warming of the southern oceans from continued increases in greenhouse gas emissions, coupled with increased freshwater input to the ocean from increased precipitation, northward transport of sea ice, and melting of sea ice, ice shelves, and Ice sheets, and the subsequent intensification of the West Pole. Warm ocean surface and freshwater anomalies are driven northward by the upper mean overturning circulation cell and deposited into the interior ocean with a regional maximum at 45°C. A rapid response to the enhanced wind speed increases the northward advection of cold water, helping to delay and reduce Southern Ocean surface warming.
Antarctic sea ice Stronger winds and greater fluxes of heat and fresh water also change circulation: stronger winds drive a stronger overturning caused by wind and stronger eddy currents; Although the latter partially offsets the former, a net overturning rotation of the upper cell is produced. The associated increase in deep-water upwelling is reversed by increasing heat and freshwater fluxes into lighter water masses and increasing heat and freshwater stores. CDW warming increases the heat pool and is transported by more energetic eddies to the Antarctic continental shelf, increased melting of the Antarctic ice shelves and the ice sheet in the latest coupled global climate models, many of the processes that affect Projected Southern Ocean warming impacts, wait. A significant improvement First, due to the relatively low resolution of these models, the full effect of eddies is not yet included, as is the interaction between open water and shelf water. which affects the melting of ice shelves and ice sheets. Most coupled models have non-interactive ice shelves and ice sheets, so their interaction with other components is absent. In addition, the Southern Ocean is a source of natural carbon and a primary sequester of atmospheric CO2. As such, the southern ocean circulation response affects any Southern Ocean warming forcing. In this context, the issue of whether and when the Southern Ocean's carbon sequestration will decrease due to intensification?
