In the northern hemisphere, winds in a cyclonic pressure system spin counter-clockwise. This counter-clockwise rotation is a result of the Coriolis effect, which is caused by the rotation of the Earth. As air moves toward the low-pressure center of the system, it is deflected due to the Earth's rotation, causing the wind to veer to the right and create a circular motion around the low pressure.

This characteristic is fundamental to understanding how weather systems operate in the northern hemisphere. Cyclones are typically associated with stormy weather and can bring precipitation, strong winds, and varying atmospheric conditions. This behavior is distinct from anticyclonic systems, which rotate clockwise in the northern hemisphere, primarily associated with clear weather.

The other options do not accurately describe the behavior of winds in a cyclonic system. Clockwise rotation is indicative of anticyclones in the northern hemisphere. Random spinning does not relate to the organized flow of air in a cyclonic system, and while winds generally flow inward toward the low-pressure center, it is their counter-clockwise rotation that is the definitive feature of cyclonic motion.
