Temperature Flashcards
What does temperature tell us
It tells us how hot or cold a place is
Temperature is measured in
Degrees celcius
What is atmospheric pressure
Atmospheric pressure is the weight of air on the earth’s surface
What instrument is used to measure temperature
It is measured with a thermometer
Atmospheric pressure is measured in ___________________________
Millibus
What instrument is used to measure atmospheric pressure
Barometer
(Aneroid Barometer & Mercury Barometer)
What is precipitation
This is how much rain, snow, sleet or hail falls from the sky
What does wind speed tell us
It tells us how fast or strong the wind is blowing
What is precipitation measured in
Precipitation is measured in millimetres (mm) / centimetres (cm)
What instrument is used to measure the wind direction
It is measured with a wind vane or a wind sock
What instrument measures wind speed
Anemometer
What unit is wind speed measured in
It is measured in miles per hour (mph) or kilometres per hour (kph)
What instrument is used to measure precipitation
Rain gauge
What unit is used to measure wind speed
It is measured in miles per hour (mph) or kilometres per hour (kph)
What is wind direction
The direction the wind is blowing from
What is wind direction measured in
Using compass directions
( North, South, East, West)
Describe the mercury barometer
It has a glass tube which is placed inside a bowl of mercury. When there is high pressure the mercury rises and when there is low pressure the mercury sinks
Describe the aneroid barometer
It has a vacuum chamber and a spindle which spins the pointer. Where the pointer falls show us whether the air pressure has increased or decreased and tells us what kind of weather we’re experiencing
What is air mass
Air mass is the weight of air with equal temperature and humidity
What is a front
A front is the area where two air masses meet
What is an anticyclone
Anticyclones are places that have high pressure and usually give good weather
What is a depression
A depression is a place that has low pressure and usually gives bad weather
