Idea

Climate Physics is about the physical processes that need to be understood to describe the climate of the earth, especially for climate models.

Details

Physical processes

Conservation of momentum

u˙=fvρ 1px+F drag x \dot u=fv-\rho^{-1}\frac{\partial p}{\partial x}+F_{drag}^{x}
v˙=fuρ 1py+F drag y \dot v=fu-\rho^{-1}\frac{\partial p}{\partial y}+F_{drag}^{y}

where ff is the Coriolis frequency or Coriolis parameter, which is proportional to sin(latitude)sin(latitude)

Equation of state

Temperature equation

Continuity equation

Conservation of mass of moisture

Moist processes

Wave processes in the atmosphere and oceans

Physics and modelling

Online Data Sources

For modelling, one needs data about the surface of the Earth and other geological information. One online data base is this one:
