What is it called when air moves from areas of high pressure to areas of low pressure?
Air generally moves from a region at high pressure to a region at low pressure. This moving air is called wind. The winds move all over and create the different wind systems on Earth.
What is an area of low pressure where air masses meet and rise?
When two air masses meet together, the boundary between the two is called a weather front. At a front, the two air masses have different densities, based on temperature, and do not easily mix. One air mass is lifted above the other, creating a low pressure zone.
What kind of weather would an anticyclone likely bring?
Anticyclones typically result in stable, fine weather, with clear skies whilst depressions are associated with cloudier, wetter, windier conditions.
What describes both cyclones and anticyclones?
Which describes both cyclones and anticyclones? Both are measured by changes in air pressure.
What is high-pressure area?
High-pressure areas are places where the atmosphere is relatively thick. Winds blow outward from these areas, although in a spiraling way. As air leaves the high-pressure area, the remaining air sinks slowly downward to take its place.
Why is a high pressure system called that?
A high pressure system has higher pressure at its center than the areas around it.
Where is the high pressure system at?
A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator.

What is high pressure ridge?
A ridge is an area of high pressure that does not have a closed circulation; it either extends from a high-pressure area or is sandwiched between a couple of lows. More often than not, a ridge of high pressure divides two low-pressure areas.
What type of weather is associated with a high pressure system?
typically. High pressure often means dry weather with sunshine. Low pressure often means clouds and precipitation. High pressure is associated with sinking air.
Is an anticyclone high or low pressure?
Anticyclones are regions of relatively high pressure on horizontal surfaces, or high geopotential height on isobaric surfaces, around which air circulates clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.
What is the meaning of anticyclones?
: a system of winds that is like a cyclone but that rotates about a center of high atmospheric pressure instead of low.
What type of air pressure is sinking?
High pressure is associated with sinking air. Air pressure is higher because it is pushing DOWN on the ground.
What is another name for a high pressure center?
High Pressure Centers: also known as anticyclones. A high pressure center is where the pressure has been measured to be the highest relative to its surroundings. That means, moving in any direction away from the "High" will result in a decrease in pressure.
What is a high air pressure?
A barometric reading over 30.20 inHg is generally considered high, and high pressure is associated with clear skies and calm weather.
What is the high pressure system?
A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator.
Why does air sink in high pressure?
High pressure is associated with sinking air. Air pressure is higher because it is pushing DOWN on the ground. When air sinks from high in the atmosphere to the lower levels it warms up and dries out. This is because air at the top of the atmosphere is less dense.
What does high air pressure mean?
High pressure means the air is heavy, and it sinks. Sinking air makes the environment very stable. Under high pressure you can generally expect sunny skies and calm weather. Low pressure is what causes active weather. The air is lighter than the surrounding air masses so it rises, causing an unstable environment.
What is anticyclone system?
anticyclone, any large wind system that rotates about a centre of high atmospheric pressure clockwise in the Northern Hemisphere and counterclockwise in the Southern. Its flow is the reverse of that of a cyclone (q.v.).
What is another name for anticyclone?
Anticyclone synonyms In this page you can discover 4 synonyms, antonyms, idiomatic expressions, and related words for anticyclone, like: warm-front, extratropical, anti-cyclone and cyclone.
What is a high-pressure area called?
anticyclone A high-pressure area, high, or anticyclone, is a region where the atmospheric pressure at the surface of the planet is greater than its surrounding environment.
What is anticyclone?
: a system of winds that is like a cyclone but that rotates about a center of high atmospheric pressure instead of low.
What is a high air pressure system?
A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator.
