The 2011 La Niña: So strong, the oceans fell
Global mean sea level (GMSL) dropped by 5 mm between the beginning of 2010 and mid 2011. This drop occurred despite the background rate of rise, 3 mm per year, which dominates most of the 18‐year record observed by satellite altimeters. Using a combination of satellite andin situdata, we show that t...

description | Global mean sea level (GMSL) dropped by 5 mm between the beginning of 2010 and mid 2011. This drop occurred despite the background rate of rise, 3 mm per year, which dominates most of the 18‐year record observed by satellite altimeters. Using a combination of satellite andin situdata, we show that the decline in ocean mass, which explains the sea level drop, coincides with an equivalent increase in terrestrial water storage, primarily over Australia, northern South America, and Southeast Asia. This temporary shift of water from the ocean to land is closely related to the transition from El Niño conditions in 2009/10 to a strong 2010/11 La Niña, which affected precipitation patterns world‐wide.
Key Points
Sea level drop in 2011 mainly caused by water exchange between ocean and land
Exchange related to 2010/11 La Nina driving regional changes in precipitation
Sea level decline is temporary as water will return to the ocean through runoff |
