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
