the primary force which causes all winds is: centrifugal force coriolis effect inertia force pressure gradient force. ANSWER: Most of the water on Earth is stored ___. Coriolis 2. In 2016, the first satellite in the GOES-R series, GOES-16, launched into orbit. . divergence aloft (t/f), Air pressure is exerted in all directions. If no button appears, you cannot download or save the media. Meteorologists name the storms in alphabetical order, and alternate with female and male names.When a storm reaches 119 kph (74 mph), it becomes a hurricane and is rated from 1 to 5 in severity on the Saffir Simpson scale. Hurricane-force winds can extend outward more than 150 miles (242 km) for a large one. We review their content and use your feedback to keep the quality high.

This in turn allows for a greater Coriolis deflection. ________ are elongated high pressure areas extending towards the poles and are associated with ________. T/F:The mercury barometer is larger and less portable than an aneroid barometer. Age of SailThe ability of ships to sail with powerful trade winds helped determine the political and engineering history of the Age of Exploration, sometimes nicknamed the Age of Sail. They begin in warm ocean waters when the surface temperatures are at least 26.6 degrees Celsius (80 degrees Fahrenheit). What best explains the high wind speeds found immediately around the low pressure center (L)? Particles from Saharan sand and dust storms can blow across islands in the Caribbean Sea and the U.S. state of Florida, more than 8,047 kilometers (5,000 miles) away.Dust storms in the tropics can be devastating for the local community. B) air temperature. To prepare butane-2-one, which of these compounds would you oxidize: propan-2-ol, butan-1-ol, butan-2ol, or 2-methyl propane-2-ol? T/F:A steep pressure gradient indicates strong winds. The strongest winds in the solar system, however, belong to its outermost planet, Neptune. AnemoiDeities representing the winds play an important role in mythologies around the world. A) false They have been instrumental in the history of exploration, communication, and trade. These dust storms are often associated with dry, low-pressure areas and a lack of tropical storms.DoldrumsThe place where trade winds of the two hemispheres meet is called the intertropical convergence zone (ITCZ). T/F:Theprevailing windis defined as the instantaneous direction of the wind at the moment of observation. (t/f), Friction at the surface results in a stronger Coriolis force. D) difference between the highest and lowest recorded pressure at any one weather station, B) balloon ascent from sea level to 3 miles. When upper atmospheric winds blow parallel to the isobars along straight paths, they are termed ________ winds. One of the most familiar of these downslope winds is the Fhn. Trade winds are generally very predictable. The air sinking towards the surface of the anticyclone not only causes the high pressure but also is associated with general subsidence, which prevents rising air and adiabatic cooling. The Coriolis effect is important only for motions that: With respect to the Coriolis force, which association is NOT correct? Tertiary circulation: it includes all the local winds which are produced by local causes such as topographical features, sea influences, etc. The complex relationships between fronts cause different types of wind and weather patterns.Prevailing winds are winds that blow from a single direction over a specific area of the Earth. Acycloneis generally defined by meteorologists as: in the opposite direction of Earth's rotation. Horizontal variations in air pressure cause a force which makes the wind blow. Rising air undergoes adiabatic cooling, which assists in the formation of clouds. This downdraft is a tornado.Depending on the temperature and moisture of the air, a tornado can last a few minutes or over an hour. the best explanation for the cause of atmospheric pressure is. The spacing of isobar lines on a map provides a visual indication of ________. When gases warm up, the atoms and molecules move faster, spread out, and rise. Anticyclone: air blows out (diverges) from the center and rotates clockwise (N. Hemisphere) or counter-clockwise (S. Hemisphere). The primary force which causes all winds is a. inertia force. Which of the following areas is most likely to experience rain or other significant weather? centripetal force Millions of farmers, especially those in the U.S. states of Oklahoma, Arkansas, and Texas, lost their land when they were unable to harvest any crops.However devastating to the economy, wind is an important way plants disperse seeds. 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. T/F:A southwest wind blows toward the northeast. That rush of air is the wind we experience. The primary force which causes all winds is: air would move directly from high to low pressure. The Coriolis force is zero at the Equator. The cause of the clockwise spiraling motion is: It takes satellite imagery to see atmospheric motion and improve our ability to forecast weather. convergence aloft and divergence at the surface The more the pressure changes over a . The primary force which causes ALL winds is: A pressure gradient force. Even strong winds are often short in duration.Trade WindsTrade winds are the powerful prevailing winds that blow from the east across the tropics. T/F: If pressure gradient was the only force acting on the air, it would move in a curved path. E) air density. Circulation in the earth's atmosphere are fundamentally caused by: A cyclone is generally defined by meteorologists as: in the opposite direction of Earth's rotation. (t/f). )Wind ZonesThe Earth contains five major wind zones: polar easterlies, westerlies, horse latitudes, trade winds, and the doldrums.Polar EasterliesPolar easterlies are dry, cold prevailing winds that blow from the east. Its readings may be too low or too high if the temperature varies from the expected. On Earth, the main differences in air pressure are caused by differences in temperature. Valuable topsoil is blown away and visibility can drop to almost zero. Why is the 500-mb level chart important for forecasting? Economic damage from the Bhola Cyclone was more than $479 million, adjusted for inflation.TyphoonTyphoons are tropical storms that develop over the northwest Pacific Ocean. Summer monsoons bring warmth and precipitation to India, Sri Lanka, Bangladesh, and Myanmar.The summer monsoon is essential for the health and economies of the Indian subcontinent. T/F: An isobar is a line connecting points of equal humidity. 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. They can travel for several kilometers before dissipating. The pressure gradient force is directed from higher to lower pressure: lines connecting points of equal air pressure. The Coriolis effect, also known as the Coriolis force, is the outcome of the earth's rotation. The Coriolis effect influences the wind by: Which of these factors influence the magnitude of the Coriolis force? where A=0.15m,k=3.5m1A=0.15 \mathrm{~m}, k=3.5 \mathrm{~m}^{-1}A=0.15m,k=3.5m1, and =1.6s1\omega=1.6 \mathrm{~s}^{-1}=1.6s1. It is determined by the mass of the object and the object's rate of rotation. The larger the difference in air pressure, the stronger the winds. Click here to download this video (1920x1080, 107 MB, video/mp4). The maximum pressure range of the atmosphere, as defined by the highest and lowest pressures ever recorded, is between: What units of pressure are used when air pressure is reported to the public in the United States? They can help you get to your destination more quickly. A gradient of pressure (high to low) is formed that causes air to flow away from the high and towards the low pressure at the surface. Spanish, Portuguese, and British ships were quick, relatively easy to maneuver, and their large, complex series of sails exploited trade winds and southern westerlies to travel across the ocean. What is the fundamental cause of horizontal pressure differences in the atmosphere? (The Coriolis Effect). The spacing of isobar lines on a map provides a visual indication of ________. both wind speed and latitude, true or false: is stronger at the equator and deminishes as you move toward the poles, upper air winds: The addition of water vapor will cause the density of air to: Air pressure drops ________ with altitude in a column of cold (dense) air than in a column of warm (less dense) air. friction between the air and the ground Note particularly the dry belts near 30 degrees North and South. Pressure gradient force, Coriolis and friction. Some equatorial air masses return to the doldrums as trade winds, while others circulate in the other direction as westerlies. Which option above is generally associated with "fair" weather? Winds converging in the center are then forced to rise, which leads to adiabatic cooling and the development of clouds and precipitation. If you want to locate the centers of high and low pressure systems, you will need a map that has: A cyclone is generally defined by meterologists as: The addition of water vapor will cause the density of the air to. )Although monsoons impact tropical as well as equatorial regions, the wind itself is created as the ITCZ moves slightly away from the Equator each season. It was flying in the Southern Hemisphere. The best explanation for the cause of atmospheric pressure is: A) weight of the air above. This form of seed dispersal is called anemochory. Generally, prevailing winds blow east-west rather than north-south. This courseware module is offered as part of the Repository of Open and Affordable Materials at Penn State. 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. wind which moves from high pressure areas to low pressure areas. T/F:The most fundamental reason for all atmospheric motions is the non-uniform heating of the earth by the Sun. The Earth would have two large Hadley cells if it did not rotate. This figure shows all six cells diagrammatically, along with the pressure variations at the surface of the Earth and zones of typical wet and dry belts. increasing the wind speed C) wind speed Tornadoes can occur as waterspouts or landspouts, spinning from hundreds of meters in the air to connect the land or water with clouds above. Cold air masses form at the poles, where the sun's radiation is less intense. The predominant summer wind direction is in favor of the batter. The latitude Image credit: Jaime Daniels, NOAA/NESDIS/STAR. The scale is named for Sir Francis Beaufort, who established a system for describing wind force in 1805 for the British Royal Navy. The addition of water vapor will cause the density of air to: Air pressure drops ________ with altitude in a column of cold (dense) air than in a column of warm (less dense) air. T/F: As seen by an observer on Earth, the Coriolis effect is an illusion; no deflection can actually be measured. its atmosphere When people get onto a bus, do they all sit on the same side of the bus first? There are three forces that cause the wind to move as it does. In some cases, this takes places in the desert, as sand dunes migrate and change shape over time. converging winds and ascending air result over the land. Its winds were about 185 kph (115 mph) as it made landfall along the coast of the Bay of Bengal, in what is today Bangladesh. (A draft is simply a vertical movement of air.) (t/f), The primary cause of wind is not atmospheric pressure but atmospheric pressure differences. Wind shear is measured in meters per second times kilometers of height. The best explanation for the cause of atmospheric pressure is: The National Weather Service measures air pressure in the unit of a millibar, which is equivalent to: If the National Weather Service converted to the metric system, they would most likely report air pressure in which units? changing the direction of the wind Friction reduces the wind speed and this decreases the Coriolis deflection. At any elevation it varies from place to place and its variation is the primary cause of air motion, i.e. Air would travel immediately from high to low pressure, which is the basic factor that creates all winds. This happens because Earths rotation generates what is known as the Coriolis effect. 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. Coriolis Force and Wind Movement. e. Coriolis effect. Neglecting friction, the speed and direction of the horizontal wind are determined by: temperature and humidity viscosity and turbulence According to researchers at University of Colorado Denver, what was the most important factor in the high number of home runs at Coors Field? Gravity (G) - causes vertical pressure differences and winds Coriolis Force (Co) - causes all moving objects, such as air, to diverge, or veer, to the right in the Earth Science, Meteorology, Engineering, Geography, Physical Geography. (t/f), During times of warmer temperature (summer), the atmospheric pressure is usually less. Currents are cohesive streams of seawater that circulate through the ocean. T/F:Horizontal wind motion can help cause vertical air motion. Colder air sinks. This illustrates the fact that: friction is present only close to the ground. No way. The wind speed normally increases with height in the layer of air next to the ground. The Tri-State Tornado killed 695 people in 3.5 hours.The best protection against a tornado is early warning. . Wind shear is higher near the coast, for example. The labeled lines on the map are called ________ and they represent lines of equal ________. The pressure gradient force is a major force in the air of the earth's atmosphere. The Enhanced Fujita Scale has 28 categories, with the strongest cataloging damage to hardwood and softwood trees.Hurricanes are measured using the Saffir-Simpson scale. It tracks clouds, temperature changes, flows of water, fire, smoke, and wind. The wettest typhoon ever recorded was Typhoon Morakot in 2009. (t/f), Gradient winds follow a curved path. The winds at the 500-mb level determine the direction of movement for weather systems. Some of the most familiar seeds dispersed by the wind are those of the fuzzy dandelion.Wind EnergyWind has been used as a source of energy for more than a thousand yearsit has pushed ships around the globe and been captured in windmills to pump water; it has turned giant stones to grind grains, make paper, saw logs, and crush ore. Today, most wind energy is used to generate electricity for homes, businesses, hospitals, schools, and industry.Wind is a renewable resource that does not directly cause pollution. A) horizontal airplane flight of 200 miles In Europe, ancient Greek myths refer to the Anemoi, or wind gods, as Boreas (north wind), Eurus (east wind), Notus (south wind), and Zephyrus (west wind). theforcethat results when there is a difference inpressureacross a surface. The Coriolis force is perpendicular to the object's axis. During summer, this means warm land-air rises, creating a space for the cool and moist air from the ocean.
