This tool observes weather
The human eye
What words describe low pressure systems. Must name at least 5.
Stormy
Rainy
Cloudy
Falling pressure
Wet

Why do temperatures vary over bodies of water and land masses?
Land heats and cools more quickly than water.
What type of clouds/front produce thunderstorms, heavy rain, and possible hail?
Cold front, cumulonimbus clouds
Which is the best explanation for how air masses move across the United States?
The prevailing westerlies move air masses from west to east across the United States but may be deflected by the jet stream.
Name the tool and what it measures. (2 answers)
This tool measures how heavy the air is at ground level.
Barometer, air pressure
Which conditions result in high winds?
Great differences in pressure
Which effect does cloud cover have on daytime temperatures during summer months?
Decreases temperatures/keeps temperatures steady
A cold air mass is moving toward a warm air mass. High levels of humidity and cumulonimbus clouds are observed in the sky. Which weather conditions are most likely?
Decrease in temperature and rain/thunderstorms
Which two factors determine the direction in which the prevailing winds blow
Uneven heating of the Earth and the rotation of Earth on its axis
This tool measures atmospheric conditions.
Weather balloon
Which best explains why the air near the top of a mountain is cooler than air at the base of a mountain?
As elevation increases, temperature and pressure decrease
How will warm waters moving up from the Gulf Stream most likely affect the local weather conditions on a North Carolina beach?
The sea breeze temperature increases
Which has the greatest effect on the temperature of a region
Amount of sunlight the area receives
What is the cause of rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America?
El Nino
What is the tool and what does it measure? (2 answers)
This tool measures the relative amount of moisture in the air.
Hygrometer and relative humidity
Rapidly falling pressure would indicate?
A severe storm
What is the most responsible for the movement of air near large bodies of water (i.e. ocean).
(Sea and Land Breeze)-- Uneven heating of land and water creates a pressure change which results in wind.
