Term
Warm air
Definition
Rises, because it's less dense and forms low pressure
Term
Cold air
Definition
Sinks, because it's more dense and forms high pressure
Term
El Nino
Definition
(the Child)
An interaction between global winds and ocean currents
It causes warm weather current towards the west coast of the Americas
Term
Global winds
Definition
Caused by unequal heating of the Earth and the rotation of the Earth (counter clockwise)
Term
Coriolis Effect
Definition
Causes global winds to curve
northern hemisphere- curves left
southern hemisphere- curves right
Term
How do global winds help the Earth?
Definition
They help distribute the Earth's temperature evenly
Term
Jet stream
Definition
(A type of global wind)
Narrow belts of strong, high speed air (there are more than 1 jet stream)
flows from west to east
directs our weather by pushing our weather systems to the east
Term
Local winds
Definition
Named according to the direction from which they blow
Term
How do the sea/land breezes work?
Definition
The land gains and loses heat rapidly
The water gains and loses heat slower than the land
DIFFERENCE IN TEMPERATURE = WIND
Term
Monsoon
Definition
Seasonal large land/sea breeze; causes rainy seasons and dry seasons due to the geography of the land and the direction the wind blows
Term
How do valley/mountain breezes work?
Definition
The thin, less dense air in the higher elevations gains and loses heat rapidly
the more dense air in the valley gains and loses heat slower
DIFFERENCE IN TEMPERATURE = WIND
Term
How are El Nino and La Nina caused?
Definition
The cause is unknown
Term
La Nina
Definition
A seasonal current of cold water similar to El Nino
