What weather phenomenon is associated with a temperature inversion?
Answer: Reduced visibility and fog near the surface
A temperature inversion traps moisture and pollutants near the surface, often causing fog and reduced visibility.
Which type of fog forms when warm, moist air moves over a cooler surface?
Answer: Advection fog
Advection fog forms when warm, moist air moves horizontally over a cooler surface, cooling the air to its dew point.
A SIGMET (WS) is issued for which conditions?
Answer: Severe or extreme turbulence, severe icing, or volcanic ash
SIGMETs are issued for hazardous weather significant to all aircraft, including severe turbulence, severe icing, and volcanic ash.
What is the standard lapse rate of temperature in the standard atmosphere?
Answer: 2°C per 1,000 feet
The standard lapse rate is approximately 2°C (3.5°F) per 1,000 feet of altitude increase in the troposphere.
Which cloud type is most associated with thunderstorm activity?
Answer: Cumulonimbus
Cumulonimbus clouds are the hallmark of thunderstorm activity, capable of reaching into the tropopause.
What does a METAR surface wind of '27015KT' indicate?
Answer: Wind from 270° at 15 knots
In a METAR, wind direction indicates where the wind is coming FROM, so 27015KT means wind from 270° (west) at 15 knots.
