Study Guide (lecture #2)

          * supplementary basic radiation formulae.

Review: (lecture #1)

- various balances & properties were listed.

- these items narrow the scope of possible circulations

Today's topics:

• - land/sea dist.
• - radiation
• - energy balance model

Chapter 3: (3.1)

Jargon:

Hemispheric differences in land & sea areas

Basic Radiation Equations:

• Planck's law
• Wien's law
• Kirchoff's law
• Stefan-Boltzmann law

short wave (solar) vs long wave (terrestrial) radiation

• observed global average distribution
• why is the sky blue?

Global radiative and heat energy balance (fig 3.4)

• short wave and longwave redistributions of energy
• surface emission exceeds shortwave input: "greenhouse" effect
• "net" surface emission (21 units) versus actual emission (116 units)
• how figure differs from more recent studies (e.g. Kiehl & Trenberth, 1997)
  
  

Energy balance models:

• -conceptual (ball & table)
• -no surface fluxes (1-layer "glass" atmosphere) -- handout, more next time
