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.
