Weather Instruments
The instrument that measures temperature.
What is a thermometer?
The blue symbol with triangles showing the direction of cool, dry air.
The area where a cold air mass crashes into a warm air mass, forcing the warm air to rise and creating stormy weather.
What is a cold front?
Clouds that are low-lying, flat, and lay like a blanket in the sky.
What are stratus clouds?
A body of air with the same temperature, humidity, and pressure throughout?
What is an air mass?
The weather conditions in an area in general or over a long period of time, verses the state of the atmosphere in an area, minute by minute.
What is the difference between climate and temperature?
The instrument that measures the atmospheric pressure.
What is a barometer?
When a warm and cold front come into contact, and the warm air slowly moves above cold air, resulting in rain.
What is a warm air mass?
Clouds that are puffy and look like cotton or cauliflower.
**most common
What are cumulus clouds?
A massive current that pulls warm water from the equator up along the east coast of the US and to the British Isles and then brings cold water back down past Africa and to the equator.
What is the gulf stream?
A front where a cold front overtakes a warm front, and forces it aloft.
**Shown by purple triangles and half circles.
What is an occluded front?
The instrument that measures the speed of the wind.
Bonus: The instrument that shows the direction of the wind.
What is an anemometer?
What is a wind vane?
Where a cold front and warm front meet, but do not move, resulting in stormy/rainy weather for multiple days.
**symbol has blue triangles and red half circles
What is a stationary front?
Clouds that are wispy, thin, and made of ice crystals.
What are cirrus clouds?
A continuous movement of ocean water from one place to another.
What is ocean currents?
The 4 types of air masses in the US.
What is maritime tropical, maritime polar, continental tropical, and continental polar?
The instrument that measure the amount of humidity in the air.
A blue H on the weather map, showing areas of clear, fair weather.
What is high air pressure?
Clouds that are tall, large, and generally produce thunderstorms.
What are cumulonimbus clouds?
A narrow band of strong air currents, encircling the globe.
What is the jet stream?
Warm air near the earth's surface rises and cools, then drops, creating this in the atmosphere.
What is a convention current?
Collect and measure the amount of rain water.
What would a rain gauge do?
A red L on the weather map, showing areas of cloudy, stormy weather.
What is low air pressure?
Clouds that are low-level, dark/grey, lay like blanket, and generally bring rain.
What are nimbostratus clouds?
A line on a map connecting points having the same atmospheric pressure at a given time or on average over a given period of time.
What are isobars?
From areas of high pressure to areas of low pressure.
What is the way winds always blow?
