Meteorology

TermDefinition
Weather The condition of the Earth's atmosphere at a particular time and place. {it can change day to day}
Air pressure The result of the weight of a column of air pushing down on an area.
Barometer The tool for measuring air pressure.
Altitude Distance above sea level
Greenhouse Effect The process by which gases are trapped and hold heat in the atmosphere like a blanket wrapped around Earth. It allows to be the right temperature for us to survive.
Anemometer The tool for measuring wind speed.

Weather forcast the 7 day condition changes in our atmosphere.
Meteorologist an expert in or student of meteorology; a weather forecaster.
Cumulus Fluffy cotton like. Low in the sky, Associated with fair weather.
Cirrus High in the sky, formed by ice. whispy, associated with fair/good weather.
Stratus Spread out flat layers, covers the sky. Blanket, low in the sky and associated with precipitatiom
Global Blow steadily from specific directions over long distances, also created by unequal heating heating of Earth's surface. Unequal heating of the equator and the poles.
Coriolis Effect The process by when wind curves because, of the Earth's rotation.
Local Winds that blow over short distances. Caused by unequal heating of the land and water. {Takes more energy to heat up a body of water than to heat up land.}
Land breeze When the wind blows from land to a body of water. AT NIGHT, the land cools more quickly than the water. The warm air above the water rises. When this happens the coolerair from the land blows i
Sea breeze When the wind blows from an ocean or lake onto land. DURING THE DAY. Cool air above the sea blows in and moves underneath the warm air from the land.
Thunderstorm a storm with thunder and lightning and typically also heavy rain or hail.
Hurricane A hurricane is a huge storm! It can be up to 600 miles across. Each hurricane usually lasts for over a week, moving 10-20 miles per hour over the open ocean. Hurricanes gather heat and energy through contact with warm ocean waters.
Tornado a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system.
Lightning the occurrence of a natural electrical discharge of very short duration and high voltage between a cloud and the ground or within a cloud, accompanied by a bright flash and typically also thunder.
Blizzard a severe snowstorm with high winds and low visibility.
Flood an overflowing of a large amount of water beyond its normal confines, especially over what is normally dry land.
Prevailing Westerlies Winds that blow between the 30 and 60 latitude marks
What directions do the winds blow in the the Northern Hemisphere? Southwest
What directions do the winds blow in the the Southern Hemisphere? Northwest
Why are these winds so important? These are the winds that cause the gulf stream to carry warm water from the equator to western europe
What is a jet stream? Bands of high speed winds that blow from west to east at speeds of 200-400 km per hour
What direction do they blow and and at what speed? West to east, 200-400 km per hour.
How can people use the jet stream? Saves time and fuel
