DRRR quiz 2
Ceiling balloon
- a balloon filled with hydrogen or other gas lighter than air, which is used to determine the height of the cloud base. This is done by measuring the time that the balloon disappears into the clouds from the time that it is released.
Barograph
- a barometer that reads and records atmospheric pressure continuously.
Radiosonde
- an instrument attached to a balloon and is used to measure temperature, pressure, and relative humidity in the atmosphere. It is equipped with a transmitter that sends data to a radiosonde receiver on the ground.
Clinometer
- an instrument that determines the height of the cloud base by measuring the distance of the cloud base to the ground.
Theodolite
- an instrument that determines wind speed and direction. It is attached to a hydrogen-filled pilot balloon and is allowed to float in the atmosphere at different heights to reach its different levels
Thermograph
- an instrument that measures and records air temperature continuously.
Doppler Radar
- calculates the motion of precipitation, estimates its type, and determines the structure of storms and their potential to cause severe weather.
Weather Surveillance Radar
- it detects and monitors the track of typhoons and cloud masses within 400 kilometers.
Wind finding radar
- it measures wind speed and direction thru radar echoes. It works by attaching a radar target to a balloon that is sent to the atmosphere. The time interval and bearing of the radar echoes are evaluated by a receiver ground radar.
Weather Satellite
- provides the synoptic view and coverage area of a weather disturbance and the capability to relay weather data from remote automatic weather stations.
rawinsonde
is like a radiosonde, but it is also capable of measuring wind velocity
