- Global wind patterns. Global wind patterns: Winds are named by the direction from which they blow. The globe is encircled by six major wind belts, three in each hemisphere. From pole to equator, they are the polar easterlies, the westerlies, and the trade winds. Show full answer.

Wind Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the Sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed

Type of Wind: Chinook or Foehn There are several different types of wind. One type is the foehn wind. This type of wind is a characteristic of mountainous areas such as the Rocky Mountains and the Alps. The wind off of the Rocky Mountains in North America is a foehn wind that is called a Chinook wind. The wind is a warm, dry wind that blows down the eastern slope of most mountains. A warm wind like this can bring relief from cold winter weather.

NSSL Research: Damaging Winds Predicting Damaging Winds. NSSL developed an algorithm in collaboration with Arizona's Salt River Project (SRP) to alert the power company of the potential for a dust storm called a haboob. A haboob is a wall of dust that is pushed out along the ground from a thunderstorm downdraft at high speeds.

Weather Glossary â Terms & Definitions Global and Local Winds, Page 1. Wind is the horizontal movement of air. All wind is caused by. the uneven heating of Earth’s surface, which sets convection. currents in motion. Convection currents on a large scale cause. global winds; convection currents on a small scale cause local winds.

- There are also other frequently asked questions about hurricanes, and these questions. are answered in Section 3. _____________________________________. 1 A major hurricane is a category 3, 4, or 5 hurricane on the Saffir/Simpson Hurricane Wind. Scale (see Table 1).

Summary 1 Upper-air winds, called geostrophic winds, blow parallel to the isobars and reflect a balance between the pressure-gradient force and the Coriolis effect. 2  Upper-air winds are faster than surface winds because friction is greatly reduced aloft.

USCG Navigation General Questions: Master's License 1 Wind is actually a form of solar energy; winds are caused by the heating of the atmosphere by the sun, the rotation of the earth, and the earth's surface irregularities.

- Global wind patterns: Winds are named by the direction from which they blow. The globe is encircled by six major wind belts, three in each hemisphere. From pole to equator, they are the polar easterlies, the westerlies, and the trade winds. All six belts move north in the northern summer and south in the northern winter.

Earth Science for Kids Global winds are created by both the spin of the Earth (Coriolis effect) and the differences in temperature between the equator and the polar areas. These winds are often grouped together as trade winds, easterlies, and westerlies. Trade winds - Trade winds occur near the equator and flow from either the north or south towards the equator.

All six belts move north in the northern summer and south in the northern winter.rade Winds: South of about 30 degrees the northern or northeast trade winds blow mostly from the northeast toward the equator. These were the sailor's favorite winds, since the weather was warm, and the winds usually blew steadily in an advantageous direction. Columbus used these to sail to the Caribbean.

- Gas and air. Gas is the most common cause of bloating, especially after eating. Gas builds up in the digestive tract when undigested food gets broken down and when you swallow air. Everyone swallows air when they eat or drink, but some people can swallow more than others, especially if they are:

- The principal wind characteristics are speed and direction. The direction of a wind is the direction from which it blows. A north wind comes out of the north and blows southward, while a west wind comes out of the west and blows eastward.

- To understand the global wind patterns it is best to first view the Earth as a fixed (non rotating) planet. (www.bom.gov.au/info/ftweather/ images/hadley3.gif) As you can see in the absence of the Coriolis effect the cold air from the poles and the warm air from the equator create 4 distinct convection cells.

Hurricane and Typhoon Hurricanes and typhoons are large and sometimes intensely violent storm systems. In meteorological terms, they are tropical cyclones that have maximum sustained winds of at least 120 km/h (75 mph). Atlantic and eastern Pacific storms are called hurricanes, from the West Indian huracan (big wind), whereas western Pacific storms are called typhoons, from the Chinese taifun, great wind. The primary energy source for a tropical cyclone is the latent heat released when water vapor condenses.

Jet stream The major jet streams are westerly winds (flowing west to east) in the Northern Hemisphere, although in the summer, easterly jets can form in tropical regions. The path of the jet typically has a meandering shape, and these meanders themselves propagate east, at lower speeds than that of the actual wind within the flow.

Winds That the Hebrews recognized the existence of four prevailing winds as issuing, broadly speaking, from the four cardinal points, north, south, east and west, may be inferred from their custom of using the expression four winds as equivalent to the four quarters of the hemisphere.esterly winds prevail in Palestine from November to February. In addition to the four regular winds, we have notice in the Bible of the local squalls, (Mark 4:37; Luke 8:23) to which the Sea of Gennesareth was liable.

Compass rose The modern compass rose has eight principal winds. Listed clockwise, these are: Although modern compasses use the names of the eight principal directions (N, NE, E, SE, etc.), older compasses use the traditional Italianate wind names of Medieval origin (Tramontana, Greco, Levante, etc.)

Atmospheric circulation There are three wind cells or circulation belts between the equator and each pole: the trade winds (Hadley cells), prevailing westerlies (Ferrell cells), and polar easterlies (polar Hadley cells).

- The Saffir-Simpson Wind Scale is a categorical classification of hurricanes based on their wind speed, used by the U.S. government's National Hurricane Center. The scale was first used in 2009, though the wind speeds of the categories match the Saffir-Simpson Hurricane Scale (see below). The scale underwent a minor modification in 2012. The categories are Category 1, 2, 3, 4 and 5: Category One Hurricane: Sustained winds 74-95 mph (64-82 kt or 119-153 km/hr).

- Wind induced oscillation There are three forms of wind induced motion as follows:-a) Galloping-Galloping is transverse oscillations of some structures due to thedevelopment of aerodynamic forces which are in phase with the motion.

Wind Measurement Wind is the natural motion of the air roughly parallel to the Earth's surface. It is caused by the unequal heating and cooling of the Earth and atmosphere by the sun, which produces differences in air pressure.
