Question 1

What does a METAR report provide?

Accepted Answer

A surface weather observation of current conditions at a specific airport

Answer

A METAR is a routine aviation weather observation providing current surface conditions including wind, visibility, sky condition, temperature, dew point, and altimeter setting.

Question 2

What does the METAR cloud entry 'OVC010' indicate?

Accepted Answer

Overcast clouds at 1,000 feet AGL

Answer

OVC means overcast (8/8 sky coverage) and 010 represents the cloud height in hundreds of feet AGL, so OVC010 = overcast at 1,000 feet AGL.

Question 3

What is a TAF?

Accepted Answer

Terminal Aerodrome Forecast — a weather forecast valid 24 to 30 hours for a 5-mile radius around an airport

Answer

A TAF provides weather forecast information within a 5-mile radius of a specific airport, valid for 24 to 30 hours, issued four times daily using METAR-like coding.

Question 4

What type of weather is typically associated with a fast-moving cold front passage?

Accepted Answer

A narrow band of intense convective weather followed by rapid clearing and improved conditions

Answer

Cold fronts move quickly and force warm moist air aloft rapidly, producing a narrow but intense band of cumulonimbus clouds, thunderstorms, and gusty gusty winds, followed by cooler, clearer air.

Question 5

What type of fog forms when warm, moist air moves over a cooler surface?

Accepted Answer

Advection fog

Answer

Advection fog forms when warm, moist air moves horizontally over a cooler surface that chills the air below its dew point, causing condensation.
