This geostrophic wind is developing in the Northern Hemisphere. This can be determined by looking at the direction of the isobars on the weather map. In the Northern Hemisphere, the geostrophic wind flows parallel to the isobars and is deflected to the right due to the Coriolis effect. In the image, the wind is flowing from high pressure towards low pressure in a counter-clockwise direction, indicating that it is in the Northern Hemisphere.
