1
Q
g≡−∇Φ.
A
gravitational acceleration
gradient of the geopotential
2
Q
the geopotential is related to
A
the work required to lift a unit mass from sea level to a given altitude.
3
Q
A
The geopotential at any level z
4
Q
A
geopotential height Z
5
Q
A
change in geopotential, dΦ
Using the hydrostatic equation, this can then be related to the density and pressure change as
6
Q
A
geostrophic wind in pressure coordinate with the geopotential height gradient
7
Q
A
hypsometric equation
8
Q
A
vertical distance between two pressure surfaces (also known as the “thickness”)
9
Q
vertical distance between two pressure surfaces (also known as the “thickness”) is
proportional to …….
A
to the mean virtual temperature of the layer
10
Q
A
thermal wind,VT
The vertical shear of the geostrophic wind
