Introduction
to atmosphere-ocean interaction
Summary
http://www.gfi.uib.no/~jenkins/SUP/PDF/sup-seminar-20070928.pdf
The
fluid circulation of the Earth and other planets is driven by energy
sources with low entropy (high temperature or direct mechanical
forcing), the energy being re-radiated at higher entropy (lower
temperature) to outer space. The energy flux through the
planetary circulation system supports a range of dissipative processes
and structures: convection cells, zonal jets, eddies, breaking wave
trains, clouds, precipitation, and so on. The principal energy
source for the atmospheric and oceanic circulation of the Earth is the
incoming flux of solar radiation, although the flux of gravitational
tidal energy from the Sun-Earth-Moon system is locally important, and
the flux of thermal energy from the Earth's interior is in principle
measurable. (The interior thermal energy flux is dominant for
Jupiter and the other giant planets of the solar system.)
In this lecture we will discuss the distribution of energy amongst the
various components of the atmospheric and oceanic circulation, and the
various contributions to the energy, momentum, and mass exchange
between the components.
Discussion points:
- What is the energy
balance of different processes, with application to the availability of
renewable energy resources?
Talks
are normally 45
minutes, and the room is usually available until 14:00 for discussions
after the talk. Anyone (from the Bergen area or elsewhere) who
wishes to give a seminar in this series is invited to contact the
Scientific Coordinator Alastair D. Jenkins <alastair.jenkins@gfi.uib.no>.
