An area of lower pressure winds that spiral toward the center is called a low-pressure system or a cyclone.

Here's why:

* Low pressure: The air in the center of the system is less dense, creating a lower pressure zone.

* Winds spiral inward: Since air naturally moves from areas of high pressure to low pressure, winds converge towards the low-pressure center.

* Rotation: Due to the Earth's rotation, these converging winds are deflected, causing them to spiral inward.

Important Note: The term "cyclone" can be used for both low-pressure systems in general and for a specific type of tropical cyclone.
