Show All Your Work.

Exercises are from the end of the Chapters in Cook (2013).

[7.2 means Chapter 7, Exercise 7.2]

  1. 7.2
  2. 7.3
  3. Consider the Hadley Circulation shown in Fig. 2.  Between the Equator and 30°N, what are the direction of the North-South transports of sensible heat, latent heat, and potential energy in the atmosphere?  Be sure to consider both the lower and upper branches of the circulation.
  4. 8.1
  5. As the Gulf Stream flows northward, the surface water gets denser both because it gets colder by latent heat flux and because the evaporation makes it saltier.  Which process increases the density more, cooling or salinity increase?  Calculate both effects, assuming that a 100 m well-mixed layer  starts in the Tropics at 28°C and cools to -1°C in the high latitudes, and starts at a salinitiy of 35 psu.  Remember the definition of the actual density of sea water, as given in the caption of Fig. 5.1.  Assume that all the cooling is due to evaporation, with no other net energy fluxes.
