the primary force which causes all winds is: the primary force which causes all winds is:

The Earth would have two large Hadley cells if it did not rotate. This Tri-State Tornado sped for 338 kilometers (219 miles) through Missouri, Illinois, and Indiana. Without going into detail as to why rotation creates this apparent force, the Coriolis effect causes winds (and all moving objects) to be deflected: The horizontal movement of air is called ________. However, typhoons have also been recorded as far as the U.S. states of Hawaii and even Alaska.Typhoons are often associated with extremely heavy rainfall. More than 147 centimeters (58 inches) of snow fell across the region, causing freezing temperatures and massive flooding as the snow melted. Figure 21. T/F:The Coriolis effect only applies to atmospheric motions; aircraft, rockets, people, etc. The Coriolis effect influences the wind by: Which of these factors influence the magnitude of the Coriolis force? Precipitation occurs where moisture-laden air rises, either by heating at the equator or by running up and over a more dense air mass. The balance of these two forces results in winds that are parallel to the isobars. Wind is always named for the direction from which it is blowing. In some cases, this takes places in the desert, as sand dunes migrate and change shape over time. These storm surges are extremely dangerous and cause 90 percent of all hurricane deaths.The deadliest hurricane on record is the Great Hurricane of 1780. C) Low wind speeds strongest deflection a. a zone where the polar easterlies and the westerlies converge. Rising air undergoes adiabatic cooling, which assists in the formation of clouds. Wind is the primary force driving surface currents in the ocean. The islands of the Philippines, China, Vietnam, and Japan are the most affected. The Altiplano region of South America has dramatically shaped ventifactsrocks carved by the wind-driven sand and ice.The winds power to erode the land can be detrimental to agriculture. A Category 5 hurricane is the strongest storm possible on the Saffir-Simpson scale. . The ACC is the largest ocean current in the world, and is responsible for transporting enormous volumes of cold, nutrient-rich water to the ocean, creating healthy marine ecosystems and food webs.Horse LatitudesThe horse latitudes are a narrow zone of warm, dry climates between westerlies and the trade winds. do not influence surface weather, in the northern hemisphere, cyclonic winds flow: D) deflection always at a 90 degree angle to the direction of air flow, C) Low wind speeds strongest deflection. Who are the experts? T/F:The most fundamental reason for all atmospheric motions is the non-uniform heating of the earth by the Sun. The term pressure gradient refers to: everywhere. The Gulf Stream brings warm water from the Gulf of Mexico up the East Coast of North America and across the Atlantic to Northern Europe. It has a significant influence on wind direction. T/F:Anticyclones characteristically have winds blowing toward their center. The sun heats the land more quickly than the water. Since gases behave differently at different temperatures, that means you also get pockets with high pressure and pockets with low pressure. The tornado thins out into the rope-like stage and dissipates a few minutes later.Most tornadoes have wind speeds of less than 177 kph (110 mph), and are about 76 meters (250 feet) across. inward and counter clockwise In 1857, Dutch meteorologist Christoph Buys Ballot formulated a law about geostrophic winds: When you stand with your back to the wind in the Northern Hemisphere, low pressure is always to your left. If air pressure is reduced by one-half for every five-kilometer increase in altitude, what would be the air pressure at a height of 25 kilometers as a fraction of sea-level air pressure? 24 Q Neglecting friction, the speed and direction of the horizontal wind are determined by: A pressure gradient and Coriolis. Divergencein the atmosphere is best defined as: Which of the following has the smallest impact on winds? As the rising air cools its capacity to hold water decreases (relative humidity increases) and, at some point, saturation with respect to water vapor is reached. The Advanced Baseline Imager (ABI) on the GOES-16 satellite can do all kinds of things. Areas where prevailing winds meet are called convergence zones. T/F:A southwest wind blows toward the northeast. These pressure variations are caused by A)greenhouse effect B)non-circular shape of earth C)warm temperatures in the stratosphere D)uneven heating of the earth's surface E)earth's rotation B)rising and expanding T/F:Stormy weather is more closely associated with anticyclones than with cyclones. You might be wondering why the air would move from high pressure to low pressure in the first place. This can be done with compass directions (ie, a north wind is one that is blowing from the north to the south) or with a degree scale where N=0, E=90, S=180, and W=270. The Coriolis force is perpendicular to the object's axis. The Tri-State Tornado killed 695 people in 3.5 hours.The best protection against a tornado is early warning. Cloud development is stifled and skies are usually clear. It probably has to do with the combination of "the conservation of angular momentum" and centrifugal force.

The spacing of isobar lines on a map provides a visual indication of ________. Each of these wind belts represents a "cell" that circulates air through the atmosphere from the surface to high altitudes and back again. The strongest winds in the solar system, however, belong to its outermost planet, Neptune. According to researchers at University of Colorado Denver, what was the most important factor in the high number of home runs at Coors Field? friction between the air and the ground Its magnitude depends on the pressure gradient, which is a measure of the spacing between isobars. AnemoiDeities representing the winds play an important role in mythologies around the world. (t/f), During times of warmer temperature (summer), the atmospheric pressure is usually less. The massive 1883 eruption of Krakatoa, an island volcano in Indonesia, had even more dramatic atmospheric results. . And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. New Orleans, Louisiana, was almost completely devastated by Hurricane Katrina. e. Coriolis effect. That rush of air is the wind we experience. A) horizontal airplane flight of 200 miles, B) balloon ascent from sea level to 3 miles, C) travel from center of a low pressure system to center of a high pressure system, D) difference between the highest and lowest recorded pressure at any one weather station. Monsoons are part of a yearlong cycle of uneven heating and cooling of tropical and mid-latitude coastal regions. Note that the U.S. lies primarily in the Westerly Wind Belt with prevailing winds from the west. Winds of a Category 5 blow at 252 kph (157 mph).Hurricanes spin around a low-pressure (warm) center known as the eye. Sinking air inside the eye makes it very calm. The primary force which causes all winds is: air would move directly from high to low pressure. Neglecting friction, the speed and direction of the horizontal wind are determined by: temperature and humidity viscosity and turbulence Germany has the most installed wind energy capacity, followed by Spain, the United States, India, and Denmark. its rotation latitude When you reach out to him or her, you will need the page title, URL, and the date you accessed the resource. Click here to download the 11x17 inch poster! The primary force which causes ALL winds is: Neglecting friction, the speed and direction of the horizontal wind are determined by: The pressure gradient force is directed from higher to lower pressure: change in pressure along a horizontal surface. Image courtesy of Hannes Grobe, Alfred Wegner Institute for . Air. The wettest typhoon ever recorded was Typhoon Morakot in 2009. T/F:Theprevailing windis defined as the instantaneous direction of the wind at the moment of observation. The maximum pressure range of the atmosphere is between: The addition of water vapor will cause the density of air to: Which of the following has the smallest impact on winds? Divergence in the atmosphere is best defined as: the primary force which causes all winds is: Neglecting friction, the speed and direction of the horizontal wind are determined by: True or False: air pressure is exerted in all directions, True or false: if the pressure gradient were at 1020 millibars it would be higher than normal, A steep pressure gradient: (t/f), The primary cause of wind is not atmospheric pressure but atmospheric pressure differences. Their empires in Africa, eastern Asia, and the "New World" of North and South America blossomed in the 16th-19th centuries. The geostrophic wind concept is most like the real atmospheric winds: When geostrophic conditions exist in the atmosphere, thenetforce on the moving air is: The geostrophic wind describes a situation where the air moves: If you stand with your back to the wind, there is low pressure on your left and high pressure on the right. Cold air masses form at the poles, where the sun's radiation is less intense. (t/f), The Coriolis effect only applies to atmospheric motions; aircraft, rockets, people, etc. T/F:Winds flow cyclonically around all areas of low pressure. The wind is the condition of speedy movement of air. (t/f), The mercury barometer is larger and less portable than an aneroid barometer. Friction reduces the wind speed and this decreases the Coriolis deflection. . The pressure gradient force is directed from higher to lower pressure: lines connecting points of equal air pressure. In both cases, pressure gradient force directs the wind directly perpendicular to the isobars, into the low pressure. The rotation of the Earth and its uneven heating by the sun also contribute to the formation of high-altitude jet streams.These strong, fast winds in the upper atmosphere can blow 480 kph (298 mph). If the winds are in front of the plane, pushing it back, they are called headwinds. Winds are deflected from their initial direction due to the earth's rotation, rather than crossing the isobars at right angles as the pressure gradient force directs. The extrasolar planets of 51 Pegasi have winds that blow 14,400 kph (9,000 mph)! Identify the choice above that represents a low pressure center (in either hemisphere). The vertical component of the air motion is usually: divergence aloft and convergence at the surface. Wind shear is measured both horizontally and vertically. Note particularly the dry belts near 30 degrees North and South. It is not, however, any windier than most other cities.The nickname most likely came from Chicagos relationship with Cincinnati, Ohio, in the 19th century.
