The QG Height Tendency Eq. can be expressed as:

2

the equation is a

partial differential equation describing the local change of the geopotential height (Φ) on an isobaric surface with respect to time

3

There are three forcing terms on the right-hand side of The QG Height Tendency Eq. From left to right, these forcing terms represent:

  1. Geostrophic vorticity advection
  2. Differential thermal advection and
  3. Differential diabatic heating.

4

The QG Height Tendency Eq. is applied to 

the study of troughs and ridges in the middle troposphere – often at 500 hPa – and not at the surface

5

The contribution to the local geopotential height tendency exclusively due to geostrophic vorticity advection can be expressed by:

6

The contribution to the local geopotential height tendency exclusively due to geostrophic vorticity advection can be expressed by:

It depicts the

advection by the geostrophic wind of the geostrophic relative (عg) and planetary vorticity (f)

7

Cyclonic geostrophic vorticity advection will result in

local decrease in geopotential height with time

8

Cyclonic geostrophic vorticity advection will result in local decrease in geopotential height with time, because:

Cyclonic geostrophic vorticity advection will result in local decrease in geopotential height with time, because:

10

Cyclonic geostrophic vorticity advection will result in local decrease in geopotential height with time, because:

11

Anticyclonic geostrophic vorticity advection will result in

local increase in geopotential height with time

12

Anticyclonic geostrophic vorticity advection will result in local increase in geopotential height with time, because:

13

Anticyclonic geostrophic vorticity advection will result in local increase in geopotential height with time, because:

14

Anticyclonic geostrophic vorticity advection will result in local increase in geopotential height with time, because:
