Doldrums
Mostly calm air in a band over the equator
Land Breeze
The breeze caused when the water stays warm and the land has cooled
Local Winds
Winds that blow over short distance
Meteorology
The study of weather, and the understanding of the forces and causes of weather
Polar Easterlies
Cold, fairly weak winds blowing from east to west
Prevailing Westerlies
Cool air, usually moving quickly toward the poles from the west to east in both hemispheres
Prevailing Winds
Winds that blow more often from one direction than the other
Sea Breeze

Trade Winds

Atmosphere
made of the layers of gases surrounding a planet or other celestial body
Barometer
a scientific instrument used to measure atmospheric pressure
coriolis effect
an apparent force caused by the earth's rotation. The Coriolis force is responsible for deflecting winds towards the right in the northern hemisphere and towards the left in the southern hemisphere.
equator
an imaginary line around the middle of a planet or other celestial body.
global winds
winds that occur in belts that go all around the planet.
jet stream
relatively narrow bands of strong wind in the upper levels of the atmosphere.
latitude
measures the distance north or south of the equator
Meteorologist
observers and researchers. They note the physical conditions of the atmosphere above them, and they study maps, satellite data, and radar information
Specific Heat
the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree
Thermometer
an instrument for measuring and indicating temperature,
Weather
the state of the atmosphere, including temperature, atmospheric pressure, wind, humidity, precipitation, and cloud cover.
Wind
the movement of air, caused by the uneven heating of the Earth by the sun and the Earth's own rotation.
