Weather Tools
Used to measure temperature
Thermometer
People who study and predict the weather are called...
Define an ocean current.
Movements of water that circulate in the ocean caused by global winds
Movement of air caused by the uneven heating of earth's surface
Wind
Spiraling high winds and extremely low pressure are unique features
Tornadoes
Sent into the stratosphere and used to gather data from the atmosphere to predict weather
weather balloon
What kind of system is associated with:
sunny, clear skies
Calm winds, spiral clockwise
Cool, dry air
High pressure system
The Jet Stream flows from the _____ to the _______.
west, east
transfer of heat through the movement of a fluid (air or water)
Convection
Electrical storms; Usually have strong winds, heavy rain, and sometimes snow, hail, or no precipitation at all
Thunderstorms
Used to show the speed of wind
anemometer
Warm air masses tend to approach from...
the south, southeast, and the east
Coriolis Effect
the flow of air from land to a body of water; A local wind flowing from the land to the sea at night.
Land Breeze
Huge, rotating storms that form over the ocean near the equator
Produce strong winds, heavy rains, and large powerful waves
Hurricanes
Used to measure air pressure
barometer
What is an air mass?
A large body of air that has relatively uniform temperature and humidity
Powerful, warm surface current in the North Atlantic Ocean
Thermal Energy is...
total energy of motion in the particles of a substance
Quickly moving cold fronts and can produce high winds, very low temperatures plus could result in blizzards, ice storms, and large accumulations of snow.
Winter Storms
used to measure amount of humidity in the air
sling psychrometer
A cooler mass of air, replacing a warmer mass of air that has low pressure
Cold Front
Explain how density impacts convection currents.
Warm air rises because particles are more spread apart. Cool air sinks because the particles are more packed together.
A boundary between 2 different air masses, neither of which are strong enough to replace the other
Stationary Front
What causes Earth’s wind and weather changes?
Differences in air pressure
