The causality is the other way round: air spirals upwards and BECAUSE of that there is low pressure on the ground. The question should be WHY does the air rises upwards and WHY does it spiral?
The spiralling comes from the coriolis effect. The rising comes from differences in mass density (lower density rises above higher density). That density difference may come from temperature differences.
High pressure areas have the contrary effect: air falls down and causes high pressure on the ground.

Why is precipitation heavier in the presistent low-pressure zones of the world?
Low barometric pressure usually indicates that air is flowing upwards. When air moves upwards it cools and the moisture in it may condense to form clouds and possibly produce rain and thunderstorms.
How do convection cells in earths atmosphere cause high-and low- pressure belts?
The convection cells radiate heat.
Does wind occurs as air moves from a place of low air pressure to a place of high air pressure?
Winds occur as air moves from high pressure to low pressure.Wind occurs as air moves from a place of low air pressure to a place of high air pressure is a true statement.
Is a tornado a violent windstorm that spirals around a rotating column of air of intense low pressure and moves in a narrow path over land?
Yes, a tornado is indeed a violent windstorm characterized by a rotating column of air with intense low pressure. It forms a narrow, rapidly spinning vortex that moves over land, causing significant destruction in its path.
As the atmosphere heats the air it becomes?
less dense and rises, creating areas of low pressure. This leads to the formation of convection currents as the warm air expands and moves upwards.
What way does low pressure air currents turn?
Low-pressure air currents typically turn counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere due to the Coriolis effect. This phenomenon occurs because the Earth rotates, causing moving air to be deflected. As air moves toward a low-pressure center, it spirals inward, creating a characteristic rotation around the low-pressure area.
How does air pressure change from high to low and from low to high?
Air pressure decreases from high to low as one moves upwards in the atmosphere due to a decrease in air density. Conversely, air pressure increases from low to high as one moves closer to the Earth's surface where more air molecules are compressed together, creating higher pressure.
Why is precipitation heavier in the presistent low-pressure zones of the world?
Low barometric pressure usually indicates that air is flowing upwards. When air moves upwards it cools and the moisture in it may condense to form clouds and possibly produce rain and thunderstorms.
What happens when air rushes into a low pressure region in the northern hemisphere?
In the northern hemisphere, air rushes from higher pressure areas towards lower pressure areas due to the Coriolis effect and pressure gradient force. This movement creates winds that rotate counterclockwise around low pressure regions.
Describe the pressure flow and condensation level of tornado?
A tornado creates an area of low barometric pressure. Air spirals into the tornado and then spirals upward within it. The low pressure in a tornado cools air flowing into it, causing moisture to condense into the characteristic funnel. In many cases, though not all, the condensation reaches all the way to the ground.
What is the difference between high pressure and low pressure?
about 40 lbs. Answer Improvement. Low pressure tires are used on farm equipment and vehicles like ATVs and the like. High pressure tire are used in industrial situations and autos and trucks. Basically because they are used on very hard or firm surfaces. Low pressure tires are used on soft and wet or marshy surfaces.
Does warm air and high pressure causes rising air?
No, warm air and high pressure typically create sinking air, as warm air is less dense than cooler air. Rising air is more commonly associated with areas of low pressure, where air is being drawn in and lifted upwards.
Why does a piece of paper blow upwards when you blow on the top?
When you blow on the top of a piece of paper, the air you blow creates a region of low pressure above the paper. This low-pressure area draws the paper upwards, causing it to rise. Additionally, the fast-moving air you blow creates momentum that lifts the paper.
How does a tornado get its speed?
Tornadoes have very low pressure at their centers, this draws air inward through the pressure gradient force. The air spirals inward and accelerates due to the conservation of angular momentum, reaching great speeds as it approaches and enters the tornado.
What direction do winds associated with a low-pressure system blow in the northern hemisphere?
It moves to the right YOUR WELCOME :)
What does high pressure move towards?
Air always flows from High Pressure towards Low Pressure. Wind is caused by the pressure gradient difference. In a high pressure system, within the Northern Hemisphere, air flows clockwise, outwards and downwards; in a low pressure system (in the NH), air flows anti-clockwise, inwards and upwards.
Why does the air pressure go down when a tornado is near?
Air pressure drops near a tornado due to the strong updrafts within the storm. The low pressure in the center of the tornado causes air from the surroundings to be drawn in, leading to a drop in air pressure in the immediate vicinity of the tornado.
