How did the US Weather Bureau (Now NOAA) find temperature and wind direction in flight's early years?

They used observations located at higher altitudes

They gathered reports from airmail pilots

They collected data from instruments that commercial pilots attached to their planes

They attached instruments to kites and tethered balloons

How many aviation weather forecasts do scientists issue each year?

4 million

4 billion

76 billion

Which statement does NOT describe the Air Force weather agency?

Provides worldwide coverage

Its data helps the military engage targets around the world

Conducts hurricane reconnaissance

Works completely independently

What are the four types of weather observations?

Surface, upper air, radar, and satellite

Cold, hot, stormy, and dry

One-day forecasts, five-day forecasts, one-week forecasts, and one-month forecasts

Troposphere, stratosphere, mesosphere, and thermosphere

Where do weather observers generally look when studying surface weather conditions?

At the highest and lowest points within a geographic county

At five weather data sites within the geographic county

Within 50 miles of an official NOAA observation site

Within a five-mile radius from a give airport

What serves as the country's main surface weather observing network?

Weather surveillance radar (WSR)

Nex gen weather radar system (NEXRAD)

Geostationary operational environmental satellite (GOES)

Automated surface observing system (ASOS)

What is an ASOS drawback?

It can't report any weather that takes place over the horizon

It can't report any event at less than 12,000 ft

It can't provide broadcasts via computer-generated voicw

It can't help pilots when they are about to land

What are the two ways that weather observers have to learn about upper air?

Anemometers and sling psychrometers

Aneroid barometers and bulb thermometers

Radiosondes and pilot weather reports

Satellites and tethered balloons

Which type of radar provides weather reports to local communities, forecasters, the military, and airport weather observers, among others?

Airborne radar

Faa terminal doppler weather radar

Doppler radar

Faa airport surveillance radar

How often does Doppler radar provide new images when it reads precipitation

Every minute

Every 2-4 min

Every 4-6 min

Every 10 min

Which type of radar detects aircraft?

Airborne radar

Faa terminal doppler weather radar

NEXRAD WSR-800 radar system

Faa airport surveillance radar

What is one of the most important weather-tracking systems in the US?

Doppler radar network called NEXRAD WSR-88D

SIGMETs

AIRMETs

AFSS

Which printed forecasts that pilots can read provide data on severe weather events and less-severe weather?

SDs

Pilot weather reports

Terminal aerodrome forecasts

In-flight weather advisories

Which type of weather chart updates the overall weather picture across the US every three hours?

Radar summary chart

Significant weather prognostic chart

Surface analysis chart

Weather depiction chart

How are significant weather prognostic charts different from other weather charts?

They compile data on severe storms from the previous week

They report current weather, they don't forecast weather

They forecast weather, they don't report current weather

These charts come in colorful displays, not just black and white, for easier reading
