Phys.org  August 14, 2024 The strength and variability of the Southern Ocean carbon sink is a significant source of uncertainty in the global carbon budget. One barrier to reconciling observations and models is understanding how synoptic weather patterns modulate air-sea carbon exchange. An international team of researchers (USA – Monterey Bay Aquarium Research Institute, NCAR, Pacific Marine Environmental Laboratory, University of Arizona, Canada, South Africa) identified and tracked storms using atmospheric sea level pressure fields from reanalysis data to assess the role that storms play in driving air-sea CO2 exchange. They examined the main drivers of CO2 fluxes under storm […]
