Answer 10

Satellite

Question 11

Radar detection devices emit and receive radio waves to determine the distance from the source of the object by measuring the time it takes for the echo of the wave to return.

Question 12

Measures the direction and the speed of moving objects, such as precipitation, and can measure the velocity.

Answer 12

Weather Radar

Question 13

Measures the temperature of any substance or atmosphere. Mercury is the substance inside

Answer 13

Thermometer

Question 14

Records air temperature continuously on graphing paper during a given period in a given area. It uses digital infrared imaging to record slight changes in temperature.

Answer 14

Thermograph

Question 15

It can tell if good or bad weather is on the way.

Answer 15

Barometer

Question 16

Barometer indicates ____ meaning “can bring storm (foul weather)”

Answer 16

Low Pressure

Question 17

Barometer indicates ____ meaning “Weather will be fair”

Answer 17

High Pressure

Question 18

Type of Barometer: Balances the mercury column, the weight of which can be measured precisely.

Answer 18

Mercurial

Question 19

Type of Barometer: An evacuated capsule deflects with changes in atmospheric pressure and is much more used than a mercurial

Answer 19

Aneroid

Question 20

Type of Barometer: Recording aneroid barometer where the changes in atmospheric pressure are recorded on chart paper. A paragraph chart is mounted onto the drum which is normally with clockwork.

Answer 20

Barograph

Question 21

Used to measure the air and wet bulb temperatures to determine the relative humidity.

Answer 21

Sling Psychrometer

Question 22

Originally designed as a weather instrument, a hygrometer is used to measure humidity. The device detects the amount of water vapour.

Answer 22

Hygrometer

Question 23

What causes lightning in the clouds?

Answer 23

air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground.

Question 24

How clouds are formed?

Answer 24

Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals.

Question 25

Thunderstorm Ingredients

Answer 25

• Moisture
• Instability
• Lift

Question 26

Stage of Thunderstorm formation: As the air lifts higher, it causes a storm to grow taller and taller. Thunderstorm clouds can rise up to 10 miles into the air.

Answer 26

Developing Stage

Question 27

Stage of Thunderstorm formation: This is the most dangerous stage of the storm, when tornadoes, hail, winds and flooding can occur.

Answer 27

Mature Stage

Question 28

Stage of Thunderstorm formation: Updrafts fuel the storm with warm, moist air. The storm weakens when it runs out of updrafts, and rain and wind become less intense.

Answer 28

Dissipating Stage

Phases of ENSO

Answer 29

Neutral Phase
El Niño Phase
La Niña Phase

Question 30
