How thick is the troposphere
10 km
Where on earth’s surface is there a net surplus of heat from the sun
Tropics
Where on earth’s surface is there a net deficit of heat from the sun
Poles
adding water vapor to air _____ its density
decreases
what is the approximate declination of the earth (aka angle of the poles relative to the plane of orbit around the sun)
23.4 degrees
At what depth in the water column is the SOFAR channel
1 km
As water pressure increases, sound travels
Faster in water
At a fixed pressure does sound move faster in colder or warmer water
faster in warmer water
The latent heat of ice melting is ___ the latent hear of water evaporating
smaller than
wind stress is proportional to wind speed to the power a:Stress ~ (WindSpeed)^a the value of a is—
2
Define wind stress
vertical transfer of horizontal momentum from the atmosphere into the ocean units (Nm^-2)
Define the atmospheric Boundary Layer
it is the boundary (transition) layer is defined as the lowest part of the troposphere, that is directly influenced by the presence of earth’s surface. Over the ocean, it is influenced by the turbulent drag of the wind on the sea and the fluxes of heat and water molecules. its thickness (Zi) varies from 10s of m (when weak winds blow over water colder than the overlaying air) to 1000m (When stronger winds blowing over water warmer than the overlaying air).
Define the Equilibrium Layer
aka the surface layer. is the lowest part of the atmospheric boundary layer, closest to the ocean surface within this layer, of thickness ~ 0.1 Zi, vertical fluxes of heat and momentum are nearly constant.
what are the worlds 5 western boundary currents
Kuroshio, Gulf stream, Agulhas, East Australian, Brazil
What are the 6 eastern boundary currents
Peru/chile, Benguela, Canary, Labrador, California, Oyashio
