Where is precipitation most likely to occur?
Most precipitation occurs within the tropics and is caused by convection. The movement of the monsoon trough, or intertropical convergence zone, brings rainy seasons to savannah regions. Precipitation is a major component of the water cycle, and is responsible for depositing the fresh water on the planet.
Which type of cloud would most likely be typical of a cold front?
Cold fronts occur when heavy cold air displaces lighter warm air, pushing it upward. Cumulus clouds are the most common cloud types that are produced by cold fronts. They often grow into cumulonimbus clouds, which produce thunderstorms. Cold fronts can also produce nimbostratus, stratocumulus, and stratus clouds.
Which weather has been most likely observed at Evansville Indiana over the past couple of hours?
Which weather has been most likely obseved at Evansville, Indiana over the past couple of hours? Likely clear and rainless.
Which type of air mass would most likely be moist and warm?
Maritime air masses form over water and are humid. Continental air masses form over land and are dry. Therefore, an air mass that develops over northern Canada is called a continental polar air mass and is cold and dry. One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid.
How are hail and snow similar?
” Snow is made up of one or more tiny ice crystals that come together to form the intricate and unique shapes of a snowflake,” says ABC weather specialist and presenter Graham Creed, “Whereas, hail is a frozen raindrop and is generally a lot bigger than a pure crystal of ice.”
What is the primary cause of winds?
The wind is caused by differences in atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.
What weather is often linked to cold fronts?
Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed.
What do cold fronts bring?
Cold fronts usually bring cooler weather, clearing skies, and a sharp change in wind direction.
What do isobars that are close together on a weather map indicate?
Isobars are lines/areas of equal pressure represented on a weather map. When isobars become very tightly grouped together it indicates a “tight pressure gradient” (steep slope). The tightly packed isobars are due to the difference in air pressure between between High and Low pressure systems.
Is 2020 a wet year?
September 2020 was warm and dry in the U.S. West, cool in the middle, and wet in the South and Southeast. For the year -to-date, the contiguous U.S. temperature was 57.3°F, 2.3°F above the 20th-century average, ranking sixth warmest in the January-September record.

What happens when air masses of different temperatures meet?
When air masses with different temperatures meet, they don’t mix together. Instead a narrow boundary forms between them which is called a front. A front is a narrow boundary between two air masses. Usually when fronts occur one air mass is moving into an area while another is moving out.
What are the 5 types of air masses?
Five air masses affect the United States during the course of a typical year: continental polar, continental arctic, continental tropical, maritime polar, and maritime tropical. Continental air masses are characterized by dry air near the surface while maritime air masses are moist.
Which is the coldest air mass?
The coldest air masses are Arctic air masses. These air masses originate at the poles of the Earth in Greenland and Antarctica. Since these areas of
Why do weather fronts form when two air masses collide?
When two different air masses come into contact, they don’t mix. They push against each other along a line called a front. When a warm air mass meets a cold air mass, the warm air rises since it is lighter. As air masses move, pushed by winds, they directly influence the weather in the regions over which they pass.
