The following graphic shows the average of the wind direction at 1000 hPa for December 2020.
The following graphic shows a high pressure area in the northern hemisphere:
A low pressure area in the northern hemisphere appears like the following graphic:
In the southern hemisphere the pressure areas are rotating in the opposite direction because the Coriolis force is inverted. So the colors are also inverted.
