At the ultimate effect, gravity is the force behind moving air.
But only because the Sun warms the air, and as the warmer air rises, more dense air moves in to take its place.
And there we have a complex interplay of the air warmed by the sun in the east, will be replaced by cooler air from the west. Hence the prevailing westerly winds.
And the next thing interacting is the Coriolis forces, which because of the rotation of the Earth, cause low pressure systems to form, and these rotate clockwise in the Southern Hemisphere, and anti-clockwise in the northern hemisphere. And the opposite directions for the anti-cyclones, the high pressure systems.
There is a philosophical question as to whether less dense air rises, or dense air sinks.
Very simply explained; air movement (wind) is caused by an exchange of heat.
In our present world, if the global temperature is rising, then as a minimum, there is an increase in the energy of the atmospheric system. This will lead to greater energy interchange between the various regions. Meaning greater variability.
What else can I help you with?
In which general direction is the hot and dry air mass most likely to move?
The hot and dry air mass is most likely to move in the direction where lower pressure systems exist. This typically means that it will move towards areas with cooler temperatures or where moist air masses are located.
What direction do high and low pressure systems move and why?
High pressure systems typically move in a clockwise direction in the Northern Hemisphere and a counterclockwise direction in the Southern Hemisphere due to the rotation of the Earth. Low pressure systems move in the opposite direction. These movements are influenced by the Coriolis effect, which deflects air masses to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, creating these circulation patterns.
In what direction did the tropical cyclone move?
In what direction did the tropical cyclone move?
In which direction does an air mass always move?
Air masses generally move from areas of high pressure to areas of low pressure. This movement is driven by differences in pressure and temperature between regions, resulting in the displacement of air masses across the Earth's surface.
What direction do tornadoes move in the Midwest?
Tornadoes in the Midwest can move in any direction, but generally travel northeast.
What direction does the air move?
Everywhere
What direction does air particles move when they cause vibration?
Air particles move back and forth in the direction of the vibration when they cause it. The energy from the vibrations is transferred through the air as sound waves.
Why did the smoke move first in an upward direction and then a downward direction?
positive air pressure then hit a negative air pressure.
What makes balloon boats move?
Balloon boats move due to the escaping air from the balloon propelling the boat forward. When the air is released from the inflated balloon, it creates a force in the opposite direction, causing the boat to move in the direction of the escaping air.
How do hovercrafts move on water?
A hovercraft can move on water by forcing air downward. The hovercraft will be lifted by the air. The craft can move by rotating the Jets of air in the direction you want to go.
In which direction does air move: from hot to cold or from cold to hot?
Air moves from hot to cold.
What direction does air above a heated surface move?
in a upward motion
In which direction does an air mass move?
Towards a region of lower pressure.
Why do freely suspended balloons move towards while blowing air?
If the balloon is exhausting air, then it will move in a direction opposite to the exhaust gas.
Why is air able to move in all directions?
Air is able to move in all directions because it is a gas and its particles are not tightly packed together. This allows air molecules to move freely and spread out in any direction.
In which direction does cool air move by water?
It will always move from an area of higher pressure to an area of lower pressure.
How does pressure cause air to move?
Pressure cause air to move because all the weight pushes up or down and causes it to go the opposite direction.
