As another example of fluid flow and the application of the nonlinear Navier-Stokes (NS) equations, we will now move outwards from the Earth’s molten core to its circulating atmosphere. Specifically, in this chapter we will look at the problem of numerically predicting the weather. Although numerical weather prediction models can be generalized into climate prediction models, we shall not delve into the latter models here. One reason is that because of the much shorter time scale involved, predicting the weather several days or a week in advance is mathematically easier than predicting how the climate will change 30 years, 100 years, or longer, from now. Fully developed climate models for the Earth involve the interaction of the atmosphere and oceans with each other as well as with the land/ice surface. Furthermore, the role of solar radiation from the Sun in driving the atmosphere{ocean{land system is extremely important. On a much longer time scale, the orbital dynamics, precession, and wobble of the Earth play an important role in climate change, e.g., in the onset and waning of ice ages.
