- 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. Winds within high-pressure areas flow outward from the higher pressure areas near their centers towards the lower pressure areas further from their centers.

- A low-pressure area, low or depression, is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure systems form under areas of wind divergence which occur in the upper levels of the troposphere. The formation process of a low-pressure area is known as cyclogenesis.

Low-pressure area For a general discussion on pressure areas, see Pressure system. A low-pressure area, low or depression, is a region where the atmospheric pressure is lower than that of surrounding locations.Low-pressure systems form under areas of wind divergence which occur in the upper levels of the troposphere.The formation process of a low-pressure area is known as cyclogenesis. Within the field of meteorology, atmospheric divergence aloft occurs in two areas.he center of the spiral-shaped cloud system is also the center of a low, and usually is where the pressure's lowest. This low-pressure system over Iceland spins counter-clockwise due to balance between the Coriolis force and the pressure gradient force. Weather system redirects here.

Learn About High and Low Air Pressure Systems By definition, atmospheric or air pressure is the force per unit of area exerted on the Earth’s surface by the weight of the air above the surface. The force exerted by an air mass is created by the molecules that make it up and their size, motion, and number present in the air.These are important factors because they determine the temperature and density of the air and thus its pressure. low pressure system, or low, is an area where the atmospheric pressure is lower than that of the area surrounding it. Lows are usually associated with high winds, warm air, and atmospheric lifting.

- It is usually used in the context of psychosocial intervention, which is commonly used alongside psycho-educational or psycho-pharmacological interventions and points toward solutions for individual challenges in interacting with an element of the social environment.owever, not all psychosocial activity is therapeutic. In some environments and social movements, such as with post-WW2 East Germany Stasi's zersetzung, which has been called psychosocial crime, the development of the individual is intentionally exploited to cause damage to the individual's ability to form social bonds.

2.1 Anticyclones (high pressure) 2.1 Anticyclones (high pressure). Anticyclones tutorial. Areas of sinking air which result in high pressure are called anticyclones (the opposite to an anticyclone is the cyclone or depression, which is covered next).High pressure systems have small pressure gradients (ie the air pressure doesn't change rapidly). This means that the winds are gentle.nticyclones often block the path of depressions, either slowing down the bad weather, or forcing it round the outside of the high pressure system. They are then called ' Blocking Highs '. As air descends, air pressure increases. When air hits the ground, it has to go somewhere.

Pressure system A pressure system is a region of the Earth's atmosphere where air pressure is a relative peak or lull in the sea level pressure distribution.The surface pressure at sea level varies minimally, with the lowest value measured 870.0 hectopascals (25.69 inHg) and the highest recorded 1,085.7 hectopascals (32.06 inHg). low-pressure area, or low, is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in upper levels of the troposphere. The formation process of a low-pressure area is known as cyclogenesis.

What IS this strange sound from the sky? Noise heard across the globe for nearly a DECADE - but nobody has an explanation . Atmospheric Pressure force exerted by the weight of the air. Atmospheric pressure is defined as the force per unit area exerted against a surface by the weight of the air above that surface. In the diagram below, the pressure at point X increases as the weight of the air above it increases.tmospheric pressure is defined as the force per unit area exerted against a surface by the weight of the air above that surface. In the diagram below, the pressure at point X increases as the weight of the air above it increases.

- On a cloudless night, especially within a high pressure system, the land surface loses heat to the atmosphere by radiation and cools. Moist air in contact with cooling surface also cools and when the temperature falls below the dew point for that air, fog forms. This type of fog is known as radiation fog.

- Air pressure. Air is light but because there is so much of it above us, it exerts a pressure on us. Air pressure is measured by a barometer. The units used are millibars. The greater the reading, the higher the pressure. A high-pressure system is called an anticyclone [anticyclone: High pressure systems, giving clear skies and gentle wind.] . Air falls in an anticyclone so no clouds are formed. In summer, high pressure usually results in clear skies, gentle breezes and fine weather.

Altitude High altitude and low pressure. Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 metres (8,000 ft) above sea level. At high altitude, atmospheric pressure is lower than that at sea level.

Overview - page 3 Atmospheric pressure is the amount of force exerted over a surface area, caused by the weight of air above it. Since fewer air molecules are present at higher elevations, atmospheric pressure decreases as altitude increases. The most common unit of measure for atmospheric pressure is the millibar (mb). On Earth, the average atmospheric pressure at sea level is 1,013 mb, while on Mars it is only 7.5 mb.

- The region where an air mass is formed is called the source region. In order to form, and air mass must remain in its source region for a week or more. Source regions must be large and uniform. Air masses are associated with anticyclones (areas of high pressure). maritime tropical – mT ο maritime polar – mP AIR MASS MODIFICATION Once an air mass moves out from its region of origin, it can become modified by the surface over which it is passing. If an air mass is colder than the surface over which it is passing it receives the designation, k.
