q |
Mid-latitude cyclone and anticyclone are the
|
|
major transient eddies that play an important
|
|
role in meridional transports of heat,
|
|
|
momentum, and moisture.
|
|
|
q |
These mid-latitude weather systems grow
|
|
|
|
from the baroclinic instability associated
|
|
|
with the strong north-south temperature
|
|
|
gradients in mid-latitudes.
|
|
|
q |
Mid-latitude cyclones have typical spatial
|
|
|
|
scales of wavenumbers 5-6 and have typical
|
|
|
time scale of 7-10 days.
|
|
|
q |
Mid-latitude cyclones are marked by well-
|
|
|
defined fronts separating the warm air mass
|
|
|
|
from the south and the cold air mass from
|
|
|
the north. (Very different from tropical
|
|
|
hurricanes, which do not have frontal
|
|
|
features).
