Extratropical cyclones can influence CO₂ uptake in the Mediterranean Sea

The CO₂ balance of the Mediterranean Sea may also depend on the action of storms crossing the region, more specifically on the influence of extratropical cyclones—meteorological systems associated with cloud cover, rainfall, wind, and thus unsettled weather. A new study by the National Institute of Oceanography and Applied Geophysics (OGS), recently published in the Journal of Geophysical Research: Atmospheres, has highlighted a relationship between periods of enhanced CO₂ uptake by the Mediterranean Sea and atmospheric circulation at the regional scale (i.e., on the order of hundreds to thousands of kilometers).
