The diameter of a typical tornado is 

WHich forces are balanced with geostrophic winds?

For an aircraft what are the meterological dangers associated with a Harmattan wind?

The geostroühic wind is greater than the gradient wind around a low pressure system because the:

The geostroühic wind is less than the gradient wind around an anticyclone because the:

In the lowerlayers of teh atmosphere due to friction the wind changes direction towards the low pressure are because :

The sea brize is a wind from teh sea 

Low level vertical wind shear can be expected during the night 

The geostrophic wind depends on 

At the approach of a warm front (northern heipshere) the direction changes from he surface up to the tropopause. The effect of thsi change is that the wind
