Which information shown on the weather maps best indicates that wind speeds in NYS were greater on December 9 than on December 8?
40 Which information shown on the weather maps best indicates that wind speeds in New York State were greater on December 9 than on December 8? (1) The isobars were closer together on December 9.
Which map best shows the general surface wind pattern around the high pressure system on December 8?
The map that best shows the general surface wind pattern around the high-pressure system on December 8 is shown in image 4.
Which side view model is best?
Answer Expert Verified. The side view model that will best show the direction of the ice movement and the locations of glacial abrasion and glacial quarrying that will form a roche moutonee is going to be model number 1.
What direction did the high pressure center move?
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.
How does wind move in a high pressure center?
Winds flow clockwise around a high pressure center in the northern hemisphere, while in the southern hemisphere, winds flow counterclockwise around a high. Sinking air in the vicinity of a high pressure center suppresses the upward motions needed to support the development of clouds and precipitation.
Why do the winds curve to the east between 30 60 degrees?
The Coriolis effect is the apparent curvature of global winds, ocean currents, and everything else that moves freely across the Earth’s surface. The curvature is due to the rotation of the Earth on its axis. Between thirty and sixty degrees latitude, the winds that move toward the poles appear to curve to the east.
What is the direction of the winds between 30 60 degrees?
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.
What causes winds to curve?
The easy answer though, is wind is caused by a difference in atmospheric pressure. In the Northern Hemisphere, the Coriolis force causes our wind to curve to the right (it curves to the left in the Southern Hemisphere).
Are trade winds warm or cold?
The trade winds blow toward the west partly because of how Earth rotates on its axis. The trade winds begin as warm, moist air from the equator rises in the atmosphere and cooler air closer to the poles sinks.
Are trade winds warm?
This warm, dry air is known as a superior air mass and normally resides above a maritime tropical (warm and moist) air mass. An increase of temperature with height is known as a temperature inversion. When it occurs within a trade wind regime, it is known as a trade wind inversion.
What causes the constant direction of the northeast trade winds?
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.”
How do jet streams influence the weather?
The fast-moving air currents in a jet stream can transport weather systems across the United States, affecting temperature and precipitation. Jet streams typically move storms and other weather systems from west to east. However, jet streams can move in different ways, creating bulges of winds to the north and south.
How does the jet stream affect the movement of air masses?
Jet streams generally push air masses around, moving weather systems to new areas and even causing them to stall if they have moved too far away. If the jet stream dips south, for example, it takes the colder air masses with it. Jet streams also have an impact on air travel and are used to determine flight patterns.
What changes the jet stream?
Climate scientists have hypothesized that the jet stream will gradually weaken as a result of global warming. Trends such as Arctic sea ice decline, reduced snow cover, evapotranspiration patterns, and other weather anomalies have caused the Arctic to heat up faster than other parts of the globe (polar amplification).
How would a weaker jet stream help cause extreme flooding?
Answer: A weaker jet stream would allow storm systems to stall in one area.
