Simulated
temperature structure
Simulated structure of east-west winds
Note in both
hemispheres the existence of an
intense eastward
flow in the upper
troposphere. These are known as jet streams.
Note also the westward flow at
the surface in the
tropics.
These plots come
from a computer
simulation of the earthÕs
atmosphere. This simulation is
quite realistic in
temperature and east-west wind structure.
