Unit 6. Weather Study Guide

Temperature is to thermometer as atmospheric pressure is to:

• high

• low

• barometer

• isobars

An area of high pressure would be characterized by which weather conditions?

• low temperature, dry and clear

• high temperature, dry and clear

• low temperature, humid and cloudy

• high temperature, humid and cloudy

Which two gasses can absorb outgoing infrared radiation, leading to an increase in atmospheric temperature?

• water vapor and hydrogen

• water vapor and carbon dioxide

• ozone and nitrogen

• oxygen and carbon dioxide

Which graph best represents the change in air pressure as altitude increases?

• 
• 
• 
• 

Which factor most directly affects the wind speed between two locations

• air pressure

• Coriolis Effect

• dew point temperature

• cloud cover

As altitude in the troposphere increase,

• pressure increases, moisture and temperature decrease

• pressure and moisture increase, and temperature decreases

• pressure and moisture decrease, and temperature decreases

• pressure, moisture and temperature all decrease

The map below shows a weather variable recorded at noon on a certain day. Isolines show values from 20 to 70. What atmospheric variable is most likely represented by the isolines on this map?

• snowfall in inches

• wind speed in knots

• air temperature in degrees Fahrenheit

• barometric pressure in millibars

On a sunny afternoon, which area will warm up the most?

• the land, because it has a lower specific heat than the water

• the land, because it has a higher specific heat than the water

• the water, because it has a higher specific heat than the land

• the water, because it has a lower specific heat than the land.

When converted to inches of Mercury, the air pressure reading of 1,017 mb at C is equal to:

• 33.00 in

• 30.30 in

• 30.03 in

• 30.00 in

Why do the clouds begin to form at the elevation of D?

• The air has cooled to the dew point temperature at this elevation

• The water droplets are too small to be seen below this elevation

• The temperature is 0^oC at this elevation

• The air below this elevation does not have condensation nuclei for clouds to form.
