ATMOSPHERE |
the layer of gases that surround the Earth
|
|
CONVECTION |
heat transfer through the atmosphere where warm air rises and cold air sinks |
|
AIR PRESSURE
|
the force of air molecules pushing on a surface that can change due to unequal heating of the planet |
|
BAROMETER
|
measures air pressure |
|
WIND
|
movement of air caused by differences in air pressure |
|
ANEMOMETER
|
measures wind speed
|
|
PSYCHROMETER
|
measures relative humidity |
|
JET STREAM |
narrow bands of strong winds in the upper levels of the troposphere |
|
LAND BREEZE |
Breeze flowing from land to the sea (night time) |
|
SEA BREEZE |
Breeze flowing from sea to land (day time) |
|
WINDWARD |
wind moves up this side of the mountain, drawing moisture out of the air. Produces a wet, moist climate |
|
AIR MASS |
large body of air where temperature and moisture are similar throughout |
|
CONTINENTAL |
dry air mass that forms over land |
|
MARITIME |
moist air mass that form over the ocean |
|
TROPICAL |
warm air mass that forms over the Tropics |
|
POLAR |
cold air mass that forms over the polar regions |
|
WARM FRONT |
forms when warm air moves over cold, denser air |
|
COLD FRONT |
forms when cold air moves under warm air |
|
STATIONARY FRONT |
a cold air mass and a warm air mass meet, and there is very little movement |
|
HURRICANE |
severe storm formed over tropical oceans with winders greater than 74 mph |
|
STORM SURGE |
Abnormal rise of water levels caused by the strong winds of a hurricane or tropical storm |
|
EYE OF THE HURRICANE |
area of warm , calm air in the center of strong tropical storms or hurricanes |
|
TORNADO |
can have stronger winds than a hurricane; forms when a cold, dry air mass meets with a warm, moist air mass |
|
LIGHTNING |
electrical discharge between a negatively and positively charged area |
|
GREENHOUSE EFFECT |
gases in the atmosphere that absorb thermal energy and radiate it back to Earth (ex: water vapor and carbon dioxide) |
|
CUMULONIMBUS |
dense, towering vertical cloud associated with thunderstorms; produced at cold front and may also contain hail |
|
GLOBAL WINDS |
Predictable air mass movement at every 30 degrees of latitude |
