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

Weather-station measurements indicate that the dewpoint temperature and air temperature are getting farther apart and that air pressure is rising. Which type of weather is most likely arriving at the station?

• a snowstorm

• a warm front

• cool, dry air

• maritime tropical air

Which temperature zone of Earth’s atmosphere contains the most water vapor?

• mesosphere

• stratosphere

• troposphere

• thermosphere

Which statement best explains why an increase in the relative humidity of a parcel of air generally increases the chance of precipitation?

• The dewpoint is farther from the condensation point, causing rain.

• The air temperature is closer to the dewpoint, making cloud formation more likely.

• The amount of moisture in the air is greater, making the air heavier.

• The specific heat of the moist air is greater than the drier air, releasing energy

Most clouds form in the atmosphere when moist

air

• rises, expands and cools to the dewpoint

• rises, expands, and warms to the dewpoint

• sinks, compresses and cools to the dewpoint

• sinks, compresses and warms to the dew point
