q |
Because of the shallowness
of the atmosphere, its motions over large
|
|
areas are primarily horizontal.
|
|
|
è |
Typically, horizontal wind speeds are a thousands time greater than
|
|
vertical wind speeds.
|
|
|
(But the small
vertical displacements of air have an important impact on
|
|
the state of the atmosphere.)
