The atmospheres condition at a given time and place with respect to temperate, moisture, wind, and barometric pressure
The average weather that occurs in a given region over a long period-typically over several decades
dry, cold climate zone above 60 degree latitude
seasonably variable climate zone between 40 and 60 degrees latitude, north or south of the equator
warm, moist climate zone near the equator
Air Mass
A very large body of atmosphere defined by basically similar horizontal air temperatures. Moisture conditions are also usually similar throughout the mass. An air mass takes on the characteristics of a place it originates.
process of heat transfer by the circulation or movement of a liquid or a gas
The amount of water vapor in the air
Jet Stream
a long narrow current of fast moving air found in the upper atmospheric levels
Aurora Borealis
Northern Lights
an instrument used to measure wind pressure
Device that measures air pressure in millibars
Relative Humidity
The link between the air's temperature and the amount of water vapor it contains
Wind Vane
measures wind direction
Acid Rain
Poisons fish, damages plants/ trees, diminishes soil
Air Pressure
This is the measure of the force with which air molecules push on a surface. It is strongest at the Earth's surface because more air is above you. As you move farther away from…
This is a mixture of gases that surrounds Earth. In addition to containing the oxygen you need to breathe, it protects you from the sun's damaging rays and is always changing.
the process by which molecules of water vapor in the air become liquid water
Someone who makes maps
Global Warming
the recent and ongoing global average increase in temperature near the Earth's surface
Greenhouse effect
trapping and build-up of heat in the atmosphere near the Earth's surface
any form of water that falls from clouds and reaches Earth's surface
Water Cycle
the continual movement of water among Earth's atmosphere, oceans, and land surface through evaporation, condensation, and precipitation
Warm Front
warmer air; light and steady precipitation; move southwest to northeast,
