As an example, pressure at any height can be diagnosed by applying the hydrostatic equation to the predicted surface pressure and the predicted values of temperature between the surface and the height of interest . Pressure is used to compute the pressure gradient force in the time - dependent equation for the winds . </P>

Gcms are used to predict specific temperatures in the near and long-term future
