Shear Lines: are associated with wind shifts
|
|
|
(direction
and speed).
|
|
|
|
– |
A
line or narrow zone across which there is an abrupt
|
|
|
change
in the horizontal wind component parallel to
|
|
|
this
line
|
|
|
|
• |
A
line of maximum horizontal wind shear.
|
|
|
|
• |
An
area of directional wind confluence along the tail end of a
|
|
surface
front.
|
|
|
|
• |
Lacks
the baroclinicity/density discontinuity of surface fronts
|
|
| • |
Fronts: The interface or transition zone between
|
|
two
air masses of different density.
|
|
|
|
– |
Density
depends on temperature and moisture content
|
|
|
|
– |
Fronts
either lie along shear lines or can lag behind
|
|
|
them.
