  1. Comparision of 5 hypsometric curves For Lower Mystic Lake (blue points are average of 3)

  2. Kalff, Ch. 11 Highlights

  3. Heat and Stratification Key ideas The Heat budget of a lake Definitions The components of the heat budget: (1-A) Rs +RLd –Rlup-LE-H +Qin-Qout-Qsed+M = rate of change in storage Individual fluxes: Shortwave radiation (from last class, mostly) Longwave radiation: Boltzmann eqn, Wein displacement law, emissivity Longwave back radiation: sky, clouds, canopy Evaporative heat flux Sensible Heat Ice formation and melting Stratification Definitions Local stability Water column stability Relationships with lake morphometry and size Vertical Mixing and entrainment Quantitative models Empirical: mass tracer or heat as a tracer
