In which of the below cases would winds be closest to geostrophic balance?

A. In meridional flow at the surface near the Equator.

B. At the surface in the eyewall of a hurricane.

C. In zonal flow at the surface near the Equator.

D. In zonal flow, just above the PBL, near 50°N

Answer:

C. In zonal flow at the surface near the Equator

Explanation:

  • As these winds have a problem with the Coriolis force that is the rotation of the earth on its axis. Occurring in mid-latitudes aloft the air currents. This balance does not occur near the surface since the friction force is significant.
  • The geostrophic winds develop in a well-defined layer of air i.e either hot or cold. In a geostrophic flow of water bodies instead of the winds moving from high to low pressure, due to the rotation of the earth.
  • The major current sin the ocean like Gulf stream and Kuroshio, and Agulhas current are all approximation and examples of geostrophic current.
