The pressure gradient force is the driving force behind wind.

You are on a boat in a fiord in Glacier Bay,Alaska.It is a clear sunny day with temperatures near 20°C with no wind.Within 5 minutes the sky is still clear but the wind is blowing at 30 knots down valley,the sea is filled with whitecaps,and the temperature drops to 5°C.What just happened?

A weather system is moving from west to east.You look at a weather map and see that you are in an area of closely spaced isobars with the center just to your east,but the spacing of the isobars increases away from you.What would you forecast for wind conditions?
