PGF formula |
(1/p)*(∆p/d) |
|
|
If distance between isobars increases, then PGF... |
Decreases |
|
|
If the ∆p increases, then PGF, |
Increases |
|
|
Coriolis force (CF) formula |
F*v (f depends on latitude) |
|
|
The max CF is located |
At the poles |
|
|
The min CF is located |
At the equator |
|
Looking at this table, which CF is larger, A or B |
CFa<CFb |
|
Looking at this table, which CF is larger, B or C |
CFb<CFc |
|
Looking at this table, which CF is larger, C or D? |
CFc<CFd |
|
Looking at this table, which CF is larger, A or C? |
CFa<CFc |
|
|
CF only influences |
Direction |
|
|
Which direction is the CF in the northern hemisphere |
To the right of the wind |
|
|
Which direction is the CF in the southern hemisphere? |
To the left of the wind |
|
|
Friction force only influences... |
Wind speed |
|
|
Friction force (FF) formula |
FF=-kv (k is a constant) |
|
|
Centrifugal force formula |
Mv^2/R |
|
|
What direction is the Centrifugal force? |
Away. (note: important forces during hurricane) |
|
Which direction is PGF and how large is the magnitude on each? |
|
|
Order the PGF's from smallest to largest |
PGF3<PGF2<PGF1 |
|
Find PGF and CF if this is the northern hemisphere and everything is in geostrophic balance |
|
|
Knowing that this is in the Northern hemisphere and is in balance, find CF, PGF and H and L |
(First locate the CF) |
|
Knowing that this is in the southern hemisphere and is in balance, find CF, PGF, H, L |
|
|
If there is a friction forces and CF is decreasing.. |
V will move toward low pressure |
|
|
El Niño temperature at the central Pacific and it's SOI( southern oscillation index) sign |
Warmer, negative |
|
|
La Niña temperature at the central Pacific and it's SOI( southern oscillation index) sign |
Colder, positive |
