wind – air that moves horizontally
convection cell – a pattern of rising and falling air, sinking air, and winds caused by unequal heating and cooling of the air

sea breeze – a wind that blows from the sea toward the land
sea breeze – a wind that blows from the sea toward the land
land breeze – a wind that blows from the land toward the sea
sea breezes vs. land breezes
Coriolis effect – no matter which way the wind blows, it will always pull toward the right in the northern
hemisphere, and to the left in southern hemisphere.

isobar – a line on a map connecting places with equal air pressure
hygrometer - an instrument that measures relative humidity.
thermometer - an instrument that measures temperature
rain gauge - an instrument that measures temperature
weather vane- an instrument that wind direction
anemometer - an instrument that measures wind SPEED
barometer - an instrument that measures air pressure
low pressure system- a weather system that usually brings rainy
weather.
high pressure system – a weather system that brings fair weather.
El Nino - an abnormal warming of surface ocean waters in the eastern tropical Pacific, is one part of
what's called the Southern Oscillation.

La Nina - an irregularly occurring movement of deep cold water to the ocean surface along the western
coast of South America that often occurs after an El Niño and that disrupts weather patterns especially in
a manner opposite that of an El Niño

Jet Stream - a long narrow wandering current of high-speed winds blowing from a generally westerly
direction several miles above the earth's surface

Gulf Stream - warm current of the Atlantic Ocean flowing from Gulf of Mexico NE along coast of U.S. to
Nantucket Island and from there eastward
