a) At 100 km from the center of a high-pressure area, located at 45°N, the wind speed is 5m/s. Compute the force per unit mass associated with the pressure gradient. b) The geostrophic velocity at 45°N is 10 m/s and the near surface velocity is 8 m/s at an angle of 30° rotated anti-clockwise from the geostrophic velocity. Compute the frictional force per unit mass acting on the near surface velocity.
