Air–sea interaction describes the processes that involve the transfer of energy, matter, and momentum between the atmosphere and the ocean.

This article is written at a definitional level only. Authors wishing to improve this entry are inivited to expand the present treatment, which additions will be peer reviewed prior to publication of any expansion.

This is one of the least well understood research topics of physical oceanography, with the theory inadequate and the data sparse. Specific areas with glaring gaps include the interaction of the wind and surface waves, the parameterization of subgrid scale processes in large–scale circulation models, and the transfer of gases across the air–sea interfaces.

Meteorology

A number of key meteorological and solar radiation effects are active at the air-sea interface; some of these key factors are:

  • Incident solar radiation affects ocean warming, but sea  (or sea ice) albedo affects the atmosphere

  • Winds: atmospheric air flow influences the sea surface in terms of energy exchange and ocean currents

  • Temperature: atmospheric temperature and ocean temperature are instrumental in heat exchange

  • Lapse rate: the thermal gradients of the atmosphere affect the thermal exchange at the air-sea interface

Mass Exchange

There are a number of important matter exchange phenomena which are important for ecological, climate and pollution research. Some of the key aspects of matter exchange are:
