7.E.1.3 & 7.E.1.4 Air Masses, Storms and Predicting Weather

What is the primary cause of rainstorms?

Earth is heated by the sun

The reading on a barometer rises when the air

pressure increases

An air mass travels north over the Pacific Ocean, from the tropics and then eastward across the US. Which weather pattern can be expected?

warm and wet

When air rises over the open ocean, a low pressure system is formed. which factor increases the potential of a low pressure system developing into a hurricane in the Northern Hemisphere?

warm water temperatures in the tropics

An air mass in a valley travels up a mountain. What causes the movement of this air

warming by solar energy re-radiated from the ground

Which is associated with hurricanes?

A storm that causes an area of low pressure beneath the warm air

Which most likely contributes to the rotational pattern of a hurricane that develops in the Atlantic Ocean/

Coriolis Effect

In the United States, lightning occurs most often in Florida. Which of these is a cause of lightning?

Discharge between rain clouds and Earth.

Doppler radar shows a vertical rotating column of air with high wind speeds. Which is most likely occurring?

Formation of a tornado

Which type of activity would MOST likely be included on a weather map

Hurricane

Earth can be viewed as an engine and heat exchange is part of the engine system. Which would be an example of a transfer of energy from the atmosphere to the lithosphere?

Hurricane moves from the Gulf of Mexico onto land

What major and potentially catastrophic events can be predicted to occur in the Northern Hemisphere between the months of June and November

Hurricanes

The latitudes at which hot deserts are found have enough direct solar heating to produce high temperatures. Which of these is another primary factor that defines deserts?

Location where atmospheric convection results in a dry air mass

Hurricanes form over water and lose wind speed when they move over land. What does this pattern BEST illustrate?

Oceans transfer more energy to the atmosphere than land does.

Barometric pressure has been dropping all day. What weather conditions will most likely occur?

Stormy weather

A high speed wind, called a jet stream is moving from the west to the east across the United States. Which characteristic of this jet stream is MOST important in predicting weather patterns?

The jet stream separates cold northern air from warm southern air

Hurricanes are large tropical storms with heavy winds that exceed 74 miles per hour. Hurricanes produce heavy rains and may give rise to tornadoes. What is the source of the energy contained in hurricanes?

Thermal energy of ocean waters

How do the conditions for a tornado differ from the conditions for a hurricane

Tornadoes form over land, while hurricanes form over bodies of water.

Which condition is associated with MOST warm fronts

cloud formations bringing precipitation

Hurricane season for the Atlantic Ocean lasts from June to November. Which factor makes an Atlantic hurricane less likely to form during the month of March?

cool ocean waters

Which two factors are most responsible for a flash flood?

how much rain is falling and how long the rain lasts

Meteorologists categorize hurricanes based on the Saffir-Simpson Scale. The scale measures the intensity and destructive potential of hurricanes. Which factor has the MOST significant effect on the strength of the hurricane?

the temperature of the water below the hurricane
