The direction of wind around a low pressure in northern hemisphere is:...
If a low-pressure area forms in the atmosphere, air flows towards this region, but will be deflected perpendicular to its velocity by the Coriolis force. Instead of flowing straight towards the low pressure area, the air ends up circulating around it.
This pattern of air flow is called a cyclone. In the Northern Hemisphere the direction of rotation around a low pressure area is counter-clockwise or anti-clockwise.

The direction of wind around a low pressure in northern hemisphere is:...
Explanation:
The direction of wind around a low pressure system in the northern hemisphere is anti-clockwise. This is due to the Coriolis effect, which is a result of the Earth's rotation. The Coriolis effect causes objects in the northern hemisphere to deflect to the right, and objects in the southern hemisphere to deflect to the left.
The direction of wind flow around a low pressure system is determined by the pressure gradient force and the Coriolis effect. The pressure gradient force is the force that causes air to move from high pressure to low pressure. In the case of a low pressure system, air is moving towards the center of the low pressure system.
However, due to the Coriolis effect, the air is deflected to the right, causing it to move in a counterclockwise direction around the low pressure system. This is because the low pressure system is rotating counterclockwise, and the Coriolis effect causes the air to be deflected to the right of its intended path.
The wind direction around a low pressure system is also influenced by the frictional force of the Earth's surface. Close to the surface, the frictional force can slow down the wind and cause it to move towards the low pressure system at a slight angle. This can cause the wind to spiral in towards the center of the low pressure system, creating a counterclockwise rotation.
In summary, the direction of wind around a low pressure system in the northern hemisphere is counterclockwise, due to the combined effects of the pressure gradient force, Coriolis effect, and frictional force of the Earth's surface.
