What instrument is used to measure wind speed?
- A.
Thermometer
- B.
Barometer
- C.
Anemometer
- D.
Hydrometer
Correct Answer
C. AnemometerExplanation
An anemometer is used to measure wind speed. It consists of cups or blades that rotate when wind blows against them. The rotation speed is then converted into a measurement of wind speed. An anemometer is specifically designed for this purpose and is commonly used in meteorology, aviation, and environmental monitoring. It is not a thermometer, barometer, or hydrometer, which are used to measure temperature, atmospheric pressure, and humidity respectively.Rate this question:

How many times a day does the National Weather Service issue weather forecasts?
- A.
2
- B.
4
- C.
10
- D.
24
Correct Answer
B. 4Explanation
The National Weather Service issues weather forecasts four times a day.

What is the device used to measure atmospheric pressure called?
- A.
Anemometer
- B.
Hygrometer
- C.
Barometer
- D.
Thermometer
Correct Answer
C. BarometerExplanation
A barometer is a device used to measure atmospheric pressure. It consists of a glass tube filled with mercury or other liquid, with one end open to the atmosphere and the other end sealed. The pressure of the atmosphere pushes down on the liquid in the tube, causing it to rise. By measuring the height of the liquid, the atmospheric pressure can be determined. This is important for weather forecasting and monitoring changes in air pressure. An anemometer measures wind speed, a hygrometer measures humidity, and a thermometer measures temperature.Rate this question:

What is the device used to measure relative humidity?
- A.
Anemometer
- B.
Hygrometer
- C.
Barometer
- D.
Thermometer
Correct Answer
B. HygrometerExplanation
A hygrometer is used to measure relative humidity. It is a device specifically designed to measure the amount of moisture or water vapor present in the air. This is done by measuring the humidity level in the air and providing a numerical value that represents the relative humidity. Unlike an anemometer, which measures wind speed, a hygrometer is designed specifically for measuring humidity. Similarly, a barometer measures atmospheric pressure, and a thermometer measures temperature, but neither of these devices is used to measure relative humidity.Rate this question:

According to the Beaufort Wind Scale, hurricane winds are given the rank of 12 (the highest) and have speeds in excess of
- A.
50 mph
- B.
117 km/hr
- C.
61-70 mph
Correct Answer
B. 117 km/hrExplanation
According to the Beaufort Wind Scale, hurricane winds are given the rank of 12, which is the highest rank on the scale. This indicates that hurricane winds have speeds in excess of 117 km/hr.Rate this question:

A radiosonde is an instrument carried on a weather balloon and may consist of the following instruments: (check 4)
- A.
Barometer
- B.
Satellite
- C.
Weather vane
- D.
Radio transmitter
- E.
Video camera
- F.
Thermometer
- G.
Hygrometer
Correct Answer(s)
A. Barometer
D. Radio transmitter
F. Thermometer
G. HygrometerExplanation
A radiosonde is an instrument carried on a weather balloon and is used to gather data about the atmosphere. It typically consists of a barometer, which measures atmospheric pressure, a radio transmitter, which sends the collected data back to the ground, a thermometer, which measures temperature, and a hygrometer, which measures humidity. These instruments help meteorologists understand and predict weather patterns. The satellite and video camera options are not typically included in a radiosonde as they are not necessary for collecting atmospheric data.Rate this question:

Mount Washington is known as the windiest mountain in the world with recorded winds speeds up to 231 mph.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Mount Washington is known as the windiest mountain in the world with recorded wind speeds up to 231 mph. This means that the statement is true. Mount Washington has a reputation for its extreme weather conditions, including strong winds. The recorded wind speeds of up to 231 mph confirm its status as the windiest mountain in the world.Rate this question:

Satellites can record and send weather information in a matter of seconds.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Satellites are equipped with advanced technology that allows them to quickly capture and transmit weather information. They are positioned in space, providing a wide view of the Earth's atmosphere and surface. This enables them to gather data from various locations simultaneously. The collected information is then transmitted back to Earth within seconds, allowing meteorologists to analyze and predict weather patterns accurately. Therefore, it is true that satellites can record and send weather information in a matter of seconds.Rate this question:

Doppler radar can determine wind speed and precipitation, but cannot tell whether it is rain or snow.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Doppler radar can determine wind speed and precipitation, but it cannot differentiate between rain and snow. This is because both raindrops and snowflakes have similar characteristics when it comes to radar reflection. Doppler radar measures the motion of particles in the atmosphere, and it can detect the movement of raindrops or snowflakes to determine the speed and intensity of precipitation. However, it cannot provide information about the type of precipitation, whether it is rain or snow.Rate this question:

Local weather reporters can give accurate weather forecasts from information from the National Weather Service.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Local weather reporters can give accurate weather forecasts because they rely on information from the National Weather Service. The National Weather Service collects data from various sources, including satellites, weather stations, and weather models, to provide accurate and up-to-date weather information. Local weather reporters have access to this information and use it to analyze and interpret the data, allowing them to provide accurate forecasts for their specific region. Additionally, local weather reporters often have knowledge of local weather patterns and conditions, which further enhances the accuracy of their forecasts.Rate this question:

An isobar is ___
- A.
A line on a weather map indicating the same temperature
- B.
A line on a weather map indicating the same barometric pressure
- C.
A line on a weather map indicating a front
Correct Answer
B. A line on a weather map indicating the same barometric pressureExplanation
An isobar is a line on a weather map indicating the same barometric pressure. Isobars connect points of equal atmospheric pressure, allowing meteorologists to analyze and predict weather patterns. By observing the distribution of isobars, meteorologists can identify areas of high and low pressure, which are important for understanding wind patterns and weather systems. Isobars are often used in conjunction with other weather symbols to depict weather conditions accurately.Rate this question:

A pilot balloon with a radio transmitter used to determine wind speed when visibility is poor is called a _____
- A.
Radiosonde
- B.
Rawinsonde
- C.
Temperasonde
- D.
Radarsonde
Correct Answer
B. RawinsondeExplanation
A pilot balloon with a radio transmitter used to determine wind speed when visibility is poor is called a rawinsonde. A rawinsonde is a meteorological instrument that is launched into the atmosphere and measures various atmospheric parameters such as temperature, humidity, pressure, and wind speed/direction. It is equipped with a radio transmitter that sends the collected data back to the ground station, allowing meteorologists to analyze and monitor weather conditions.Rate this question:
