Regents Earth Science Weather and Climate

Dry areas caused by sinking air and diverging surface winds are located at which two latitudes?

• 0º and 30º N

• 30º N and 30º S

• 0º and 60º S

• 60º N and 60º S

The average temperature at Earth's North Pole is colder than the average temperature at the Equator because the Equator

• receives less ultraviolet radiation

• receives more intense insolation

• has more cloud cover

• has a thicker atmosphere

Adjacent water and landmasses are heated by the morning Sun on a clear, calm day. After a few hours, a surface wind develops. Which map best represents this wind's direction?

• 
• 
• 
• 

The station model shows several weather variables recorded at a particular location. What was the most likely dewpoint at this location?

• 32º F

• 40º F

• 61º F

• 70º F

The diagram shows how prevailing winds cause different weather conditions on the windward and leeward sides of a mountain range. Clouds usually form on the windward sides of mountains because this is where air

• rises and cools

• rises and warms

• sinks and cools

• sinks and warms

A psychrometer is used to determine which weather variables?

• wind speed and wind direction

• percentage of cloud cover and cloud height

• air pressure and air temperature

• relative humidity and dewpoint

The diagram represents an aneroid barometer that shows the air pressure as 125, in inches of mercury. When converted to millibars, the air pressure is:

• 1009.0 mb

• 1012.5 mb

• 1015.5 mb

• 1029.9 mb

A dry-bulb temperature of 30º C and a wet-bulb temperature of 29º C were recorded at a weather station. What are the relative humidity and the most likely weather conditions?

• Relative humidity is 29% with clear skies.

• Relative humidity is 29% with a good chance of snow.

• Relative humidity is 93% with clear skies.

• Relative humidity is 93% with a good chance of rain.

What is the difference in the air temperature and humidity between the cP and mT air masses?

• The cP air mass is warmer and less humid.

• The cP air mass is colder and more humid.

• The mT air mass is warmer and more humid.

• The mT air mass is colder and less humid.

Based on the dry-bulb temperature and the wet-bulb temperature, what is the relative humidity?

• 66%

• 58%

• 51%

• 12%
