What happens when warm air is forced up and over a mass of cooler air?
In other words, the warmer air mass is forced to rise over the colder air mass. As air from the warm air mass rises, it cools, leading to the development of clouds and maybe precipitation. Large areas of clouds and precipitation are common near weather fronts.
What occurs near Earth’s surface around an anticyclone?
A seasonal reversal of wind direction associated with the large continents, especially Asia. is the result of horizontal differences in air pressure. of air occurs near Earth’s surface around an anticyclone.
Which of the following devices is used to determine wind direction?
An anemometer is a device used for measuring wind speed and direction. It is also a common weather station instrument. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in meteorology.
Which of the following is a cloud of vertical development?
A cumulus cloud that exhibits significant vertical development (but is not yet a thunderstorm) is called cumulus congestus or towering cumulus.
What happens when two air masses collide?
When two different air masses come into contact, they don’t mix. They push against each other along a line called a front. When a warm air mass meets a cold air mass, the warm air rises since it is lighter. At high altitude it cools, and the water vapor it contains condenses.
What causes air masses to rise?
Air masses build when the air stagnates over a region for several days/weeks. To move these huge regions of air, the weather pattern needs to change to allow the air mass to move. One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream.
Are anticyclones dangerous?
Indeed, Summer anticyclones can result in “Heat wave” conditions with temperatures significantly above average. One such event occurred in the summer of 2003 affecting continental Europe and the UK, it proved to be particularly hazardous to humans. The anticyclone of 2003 was hazardous in several ways.
Is an anticyclone high or low pressure?
Weather: anticyclones and depressions. As air masses move around the globe, so air pressure changes. Areas of high pressure are called anticyclones, whilst low pressure areas are known as cyclones or depressions.
Is a hurricane an anticyclone?
Cyclones and anticyclones are both wind systems indicating distinctive weather patterns, but they have opposite characteristics. A major difference is that a cyclone is a low pressure system and an anticyclone is a high pressure system.
What is the symbol for wind direction?
Wind Speed And Direction The wind direction is plotted as the shaft of an arrow extending from the station circle toward the direction from which the wind is blowing. The wind speed is plotted as feathers and half-feathers representing 10 and 5 knots, on the shaft on the wind direction arrow. See the following table.
How do you read wind direction symbols?
The staff part of a wind barb shows wind direction. The dot end of the staff is where the wind is blowing to, while the top of the staff shows the direction from which the wind is coming. The top row of wind barbs in the figure to the right all indicate a north wind.
How do you describe wind direction?
Wind direction is typically reported in degrees, and describes the direction from which the wind emanates. A direction of 0 degrees is due North on a compass, and 180 degrees is due South. A direction of 270 degrees would indicate a wind blowing in from the west.
Which type of cloud is found at high altitudes?
Cirrus clouds are the highest of all clouds and are composed entirely of ice crystals. Cirrus clouds are precipitating clouds, although the ice crystals evaporate high above the earth’s surface.
What are the 5 names of the low level clouds?
Low – level clouds (0-2 km): stratus, cumulus, cumulonimbus, and stratocumulus.
What are mid and high level stratus clouds called?
Cloud identification and classification throughout the homosphere
|Form Level||Stratiform non-convective||Cirriform mostly non-convective|
|Multi-level or moderate vertical||Nimbostratus|
