Which term refers to a weather system with counterclockwise flow around a low pressure in the Northern Hemisphere?

In the Northern Hemisphere, winds around a low-pressure system spiral inward and rotate counterclockwise due to the Coriolis effect. This circulating pattern around a low is what we call a cyclone. So when a weather system has counterclockwise flow around a low pressure, the best term to describe it is cyclone. The opposite arrangement—high pressure with clockwise flow—is an anticyclone. Monsoon refers to a seasonal reversal of winds and associated rainfall, not the basic rotation around a low. A gale is simply a strong wind, not the circular flow around a low-pressure system.
