Tornado is a violent wind storm consisting of a tall column of air which spins around very fast and causes a lot of damage. The average speed of tornado is between 64 to 160 km/h, and its length can be 250 feet across. Define Typhoon: Typhoon is a violent tropical storm with very strong winds, which occurs especially in the region of the Philippines, India, and the China Sea a severe storm in which the wind spins in a circle. duster noun. American informal a dust storm. dust storm noun. a storm during which a very strong wind blows a lot of dry soil around. electric storm a tropical storm with strong winds that move in circles. windstorm noun. a period of bad weather when there is a lot of wind but no rain. Moving air is called wind. Air currents are winds that move in a riverlike flow in a certain direction. Thermal updrafts are gentle currents caused by warm air rising. Birds like eagles or California condors often ride these updrafts high into the sky. Jet streams are rapidly moving cold currents that circle the Earth high in the atmosphere In general, wind speed and direction are almost never constant in space or time. The variation of the wind in space is called wind shear. A particular form of wind shear produces a particular form of wind variation called vorticity. Vorticity is a.. It blows in a full circle. International Standard Version The wind blows southward, then northward, constantly circulating, and the wind comes back again in its courses. JPS Tanakh 1917 The wind goeth toward the south, And turneth about unto the north; It turneth about continually in its circuit, And the wind returneth again to its circuits

Atmospheric Pressure and Winds. A few basic principles go a long way toward explaining how and why air moves: Warm air rising creates a low pressure zone at the ground. Air from the surrounding area is sucked into the space left by the rising air. Air flows horizontally at top of the troposphere; horizontal flow is called advection d. a type of wave-cut platform. b. the distance that wind travels across open water. Waves begin to feel bottom when water depth is ____. a. equal to half of the wavelength. b. equal to the wavelength. c. twice as great as the wavelength. d. three times as great as the wavelength. a. equal to half of the wavelength A violent tropical storm in which strong winds move in a circle: _ _ c _ _ _ _ A. Cyclone. A Cyclone from High in the Sky. Q. An extremely strong wind: _ a_ _ A. Gale. They are called by different names in different regions of the word. Question 2: Match the sentences in Column A with the meanings of 'hope' in Column B a wind that blows in the same direction in which a vehicle is moving. A wind that blows directly towards a vehicle is called a headwind In mature hurricanes, strong surface winds move inward towards the center of the storm and encircle a column of relatively calm air. This nearly cloud-free area of light winds is called the eye of a hurricane and is generally 20-50 km (12-30 miles) in diameter.From the ground, looking up through the eye, skies may be so clear that you might see the stars at night or the sun during the day
This is called the Coriolis Effect. The Coriolis Effect, in combination with an area of high pressure, causes the prevailing winds—the trade winds—to move from east to west on both sides of the equator across this 60-degree belt A strong wind slows down, often over some type of obstacle, such as a rock or some vegetation and drops its sand. As the wind moves up and over the obstacle, it increases in speed. It carries the sand grains up the gently sloping, upwind side of the dune by saltation. As the wind passes over the dune, its speed decreases 1.A Violent Tropical Storm In Which Strong Winds Move In A Circle. 2. An Extremely Strong Wind.... Question: 1.A Violent Tropical Storm In Which Strong Winds Move In A Circle
This is a very important function of wind, one that we do not often speak about. Through a similar process, called anemophily, wind can disperse pollen. It happens all the time, as in the case of oak, and grasses. Third example, wind can damage soil over time, that is erosion. Indeed it can move sand from one continent to another However the environment far above us impacts their movement. High in the atmosphere, narrow bands of strong wind, such as the jet streams, steer weather systems and transfer heat and moisture around the globe. Coriolis effect. As they travel across the Earth, air masses and global winds do not move in straight lines It is also called air pressure. Air pressure is measured by a barometer. 29.92 is the average air pressure at sea level. Barometric pressure is very low in a hurricane. counterclockwise Counterclockwise motion goes in a circle in the opposite direction from the way a clock moves. Hurricane winds blow in a counterclockwise direction. cyclon The Gulf Stream, together with its northern extension the North Atlantic Drift, is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and stretches to the tip of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean as the North Atlantic Current.The process of western intensification causes the Gulf. Note that while the southern hemisphere winter wind field is very zonal, the northern hemisphere winter wind field has a noticeable sinusoidal (wavy) variation around a latitude circle. Also note that as you move poleward in the southern hemisphere winter, the gradient in the zonal wind field is very strong, much stronger than is the case in.
BASIQ 2021. 3 - 5 June 2021, The University of Foggia, Italy. Menu. Home; About the conference. Keynote-Speakers; Board. Conference Chair The violent tropical wind could take action and moves towards the circle. Therefore, these bring forth attention in delivering strong winds and make it due to hurricane and violent storm. It has been established in moving around a violent tropical storm in strong winds. It makes difference in the storms and includes violent tropical storm
A wind that blows from west to east is called a westerly wind. The direction of origin is the name of the wind . Gravity Wind: A wind directed down a slope caused by greater air density near the slope than at the same height at a distance from the slope. (Also called drainage or downslope wind) A violent tropical storm in which strong winds move in a circle: __ __ c __ __ __ __ 2. An extremely strong wind: __ a __ __ I called early in the hope of speaking to her before she went to school. - showing concern that what you say should not offend or disturb the other person: a way of being polite 6. Just when everybody had given up.
The tendency for air to move from an area of high pressure to an area of low pressure is called the pressure gradient force (PGF). Now if the earth didn't rotate about its axis the wind would. A region of accelerated wind speed along the axis of a jet stream. JET STREAM A narrow band of strong winds usually found at elevations from 20000 to 50000 feet. back to top. K. KNOT A nautical unit of speed equal to the velocity at which one nautical mile is traveled in one hour. Used primarily by marine interests and in weather observations Wind can be defined as air currents or moving mass of air from high pressure areas to low pressure areas. Typically, air under high pressure normally moves towards areas under low pressure. Thus, the greater the pressure difference, the faster the flow of air which creates moving air with considerably strong force
. A jet stream is a type of air current that forms high in the atmosphere. The Sun heats Earth unevenly, creating masses of colder air near the poles and warmer air near the equator. Credit: NOAA/JPL-Caltech. On average, jet streams move at about 110 miles per hour Figure 12.1. 1: Particle motion within a wind-blown wave. Waves are created when wind blows over the surface of the water. Energy is transferred from wind to the water by friction and carried in the upper part of the water by waves. Waves move across the water surface with individual particles of water moving in circles, the water moving.
A downburst is a strong downdraft that induces an outward burst of damaging winds on or near the surface. Downbursts can be large, called a macroburst (2.5 miles or large outflow diameter and damaging winds lasting 5 to 20 minutes) or small, called a microburst (less than 2.5 miles outflow diameter with peak winds lasting only 2 to 5. , a full-scale two-story red brick house will be hit with the equivalent of 186-mile-per-hour winds and sprayed with water until it is on the brink of collapse Both observations (of real tornadoes), computer simulations, and laboratory studies (in tornado vortex chambers) have shown that the surface roughness, i.e., the measure of how disrupted the wind near the ground is by objects such as dirt, rocks, hills, trees, and even houses, can either increase or decrease the wind speeds in a tornado
This is shown on a synoptic chart with isobars that are very close together and we feel strong winds as a result. In terms of the wind direction, air moves around high pressure in a clockwise direction and low pressure in an anticlockwise direction, so isobars also tell us the direction and speed of the wind For any particular location, a hurricane strike occurs if that location passes within the hurricane's strike circle, a circle of 125 n mi diameter, centered 12.5 n mi to the right of the hurricane center (looking in the direction of motion). This circle is meant to depict the typical extent of hurricane force winds, which are approximately 75 n. These winds are called the trade winds. Farther from the Equator, the surface winds try to blow toward the Poles, but the coriolis effect bends them the opposite direction, creating westerlies Wind is the natural movement of air or other gases relative to a planet's surface. Wind occurs on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth
The strong winds of Antarctica are called katabatics, formed by cold, dense air flowing out from the polar plateau of the interior down the steep vertical drops along the coast. It is at the steep edge of Antarctica that the strong katabatic winds form as cold air rushes over the land mass There are two features that dictate wind direction in weather. The first is how winds circulate around high pressure and low pressure systems. The other is our local terrain of mountains and. Geostrophic winds exist in locations where there are no frictional forces and the isobars are striaght. However, such locations are quite rare. Isobars are almost always curved and are very rarely evenly spaced. This changes the geostrophic winds so that they are no longer geostrophic but are instead in gradient wind balance.They still blow parallel to the isobars, but are no longer balanced. The wind speed can double around the corners, Chen said. The wind tunnel effect can be felt flowing between two tall buildings as well, as is the case with the two residence halls. The closer proximity creates a smaller space for wind to travel. Therefore, the air pressure drops, causing the wind to move faster and circle between the two. Tropical cyclone, also called typhoon or hurricane, an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain.Drawing energy from the sea surface and maintaining its strength as long as it remains over warm water, a tropical cyclone generates winds that exceed 119 km (74 miles) per hour
These are called gradient currents and occur following situations where the wind or atmosphere pressure gradient causes a tilting of the lake surface (denivellation). In cases where the Coriolis force is a significant factor, the flow down a lake will tend to move toward the right (in the Northern Hemisphere) In Southern California, these freakish winds are called Santa Ana winds, strong down-slope winds that blow through the Santa Ana Mountain passes at speeds of 40 mph (64 kph), according to the.

In low pressure systems winds tend to spin counterclockwise in the northern hemisphere. Just south of the Arctic Circle, there is a very large low pressure system that tends to remain stationary Four Strong Winds Lyrics: Four strong winds that blow lonely / Seven seas that run high / All those things that don't change come what may / But our good times are all gone / And I'm bound for.
Equator - The imaginary great circle of 0 degrees latitude on the Earth's surface, separating the Northern Hemisphere from the Southern Hemisphere. Erosion - The wearing away of the Earth's surface by the action of the sea, running water, moving ice, precipitation or wind. Evaporation - The process of changing a liquid (like water) to a vapor. The wind called the norther in Texas is really not a local wind but rather is a synoptic scale or macroscale phenomenon. Strong high pressure center located over the frozen landscape of Northern Asia. 109. In the Southern Hemisphere, winds move out of a high pressure cell in a clockwise direction. True. False. 110. A steep pressure. Wind-generated waves. Wind-waves are a result of wind disturbing the ocean surface and displacing water. Natural forces, such as the water's surface tension (capillarity), or gravity, work to restore the disturbed water to its calm state, flattening the water's surface. Different types of waves are named for their restoring force Global Winds and Coriolis Effect. Wind envelopes the Earth and is of importance to everyone. The winds that encircle the entire planet is called global winds. There are a lot of names for global winds but the most popular names are the prevailing westerlies, polar easterlies, trade winds, and equator winds. The process by which wind encircles. • Surface cyclones move in the direction of the upper tropospheric flow! •The storm speed and direction can also be identified on the 500 mb map. Cyclones move in the direction of the 500 mb flow, the 500 mb flow is also called the steering flow. The cyclone also moves at about half the speed of the 500 mb flow
Gale refers to a current of air that measures in the range of 32 to 63 miles per hour on the Beaufort scale.. More generally, it's any strong wind: On this links-style course, autumn gales blow fiercely across the moors - so fiercely that a misstruck shot can turn on you like a rogue boomerang. — Joseph P. Kahn, The Boston Globe, 11 Nov. 200 gale, whirlwind, cyclone, hurricane, tornado, typhoon. A violent tropical storm in which strong winds move in a circle. MARK AS BRAINLIST. Niccherip5 and 5 more users found this answer helpful 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 Definition of a derecho. A derecho (pronounced similar to deh-REY-cho in English, or pronounced phonetically as ) is a widespread, long-lived wind storm. Derechos are associated with bands of rapidly moving showers or thunderstorms variously known as bow echoes, squall lines, or quasi-linear convective systems
Damaging winds are classified as those exceeding 50-60 mph. Damage from severe thunderstorm winds account for half of all severe reports in the lower 48 states and is more common than damage from tornadoes. Wind speeds can reach up to 100 mph and can produce a damage path extending for hundreds of miles Weather Sayings and Meanings. Red sky at night, sailors delight. Red sky in morning, sailors take warning.. A reddish sunset means that the air is dusty and dry. Since weather in North American latitudes usually moves from west to east, a red sky at sunset means dry weather—good for sailing—is moving east. Conversely, a reddish. Precipitation moving perpendicular to the radar beam (in a circle around the radar) will have a radial velocity of zero, and will be colored grey. The velocity is given in knots (10 knots = 11.5 mph)
In general, dunes move in the same direction the wind is blowing. A dune has one gently sloped side and one steep side. The gently sloped side faces the wind. It is called the windward slope. The wind constantly moves sand up this side. As sand moves over the top of the dune, the sand slides down the steep side. The steep side is called the. The strong spirally circulating wind around the centre is called the eye. The diameter of the circulating system can vary between 150 and 250 km. The eye is a region of calm with subsiding air Wind is moving air and is caused by differences in air pressure within our atmosphere. Air under high pressure moves toward areas of low pressure. The greater the difference in pressure, the faster the air flows. In 1934, on the roof of a little wooden building atop Mount Washington, in New Hampshire, an instrument to measure wind speed, called. In the Southern Hemisphere, winds traveling toward the equator will move eastward, and winds traveling toward the South Pole will curve west. When these winds collide, they will swirl clockwise in.
The trade winds move from the middle latitudes toward the equator. They are called trade winds because they created an easy route for early explorers' sailboats. The trade winds converge near the equator in area called the doldrums, where the air rises and is characteristic of calm, warm winds. Winds in this region are strong (about force 6 or 7) and the pressure gradient is much less than in the eye-wall. Here angle of indraft of wind is about 45º and this gradually decreases to 0º in the eye wall. In this area, the cirrus cloud can be in the form of strands or filaments with aligned conditions and points towards the storm centre The image below is of a hurricane (called cyclone in the Southern Hemisphere). Note the eye at the center. Image by: OSEI. Skies are often clear above the eye and winds are relatively light. It is actually the calmest section of any hurricane. The eye is so calm because the now strong surface winds that converge towards the center never reach 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. This is called anticyclonic flow. Air from higher in the atmosphere sinks down to fill the space left as air is blown outward Winds form as they more from high pressure areas near the poles toward the low pressure areas 30 degrees below each of the poles. You can see from the pictures that these winds blow from the East to the West. The winds are therefore called Polar Easterlies . Polar fronts move further south in the winter and shift northward during the summer.
In the western North Pacific, hurricanes are called typhoons; similar storms in the Indian Ocean and South Pacific Ocean are called cyclones. Major Hurricane: A tropical cyclone with maximum sustained winds of 111 mph (96 knots) or higher, corresponding to a Category 3, 4 or 5 on the Saffir-Simpson Hurricane Wind Scale As these winds move away from the equator, they turn to have an increasingly westerly component as they approach 30° latitude. Near 30° latitude in each hemisphere is a persistent belt of strong westerly winds at the tropopause called the subtropical jet. This jet meanders north and south a bit Updrafts can also be caused by the sun heating the ground. The heat from the ground warms the surrounding air, which causes the air to rise. The rising pockets of hot air are called thermals . Downdrafts occur on the downwind side of a hill or mountain. Downdrafts are often found in the vicinity of strong thunderstorms In the same way, the large atmospheric winds that circle the earth are created because the land near the earth's equator is heated more by the sun than the land near the North and South Poles. Today, wind energy is mainly used to generate electricity. Wind is called a renewable energy source because the wind will blow as long as the sun shines
