Weather Theory - FAA Questions

The suffix 'nimbus,' used in naming clouds, means

• a rain cloud.
• a cloud with extensive vertical development.
• a middle cloud containing ice pellets.

Cold air generally contains:

• More suspended water particles.
• More water vapor than cold air.
• Less water vapor than warm air.

A temperature inversion would most likely result in which weather condition?

• An increase in temperature as altitude is increased.
• Good visibility in the lower levels of the atmosphere and poor visibility above an inversion aloft.
• Clouds with extensive vertical development above an inversion aloft.

What are the standard temperature and pressure values for sea level?

• 15 °C and 29.92 inches Hg.
• 59 °F and 29.92 millibars.
• 59 °C and 1013.2 millibars.

What situation is most conducive to the formation of radiation fog?

• Moist, tropical air moving over cold, offshore water.
• Warm, moist air over low, flatland areas on clear, calm nights.
• The movement of cold air over much warmer water.

Inland fog is most likely:

• Precipitation Induced fog.
• Advection fog sometimes called sea fog.
• Radiation Fog sometimes called ground fog.

Determine the pressure altitude at an airport that is 1,386 feet MSL with an altimeter setting of 29.97.

• 1,451 feet MSL.
• 1,562 feet MSL.
• 1,341 feet MSL.

The layers of the atmosphere, beginning at the earth’s surface, are:

• Troposphere, stratosphere, and mesosphere.
• Troposphere, mesosphere, and stratosphere.
• Stratosphere, mesosphere, and troposphere.

A nonfrontal, narrow band of active thunderstorms that often develop ahead of a cold front is a known as a

• Dry Line
• Squall Line
• Prefrontal System

Clouds, fog, or dew will always form when

• water vapor condenses.
• relative humidity reaches 100 percent.
• water vapor is present.
