weather

the current state of the atmosphere

meterology

the study of atmospheric pressure

climate

the average of weather over the coarse of many years

coriolis effect

the curving of the path of a moving object from an otherwise straight path due to earth's rotation

jet stream

narrow air currents that flow quickly through the amosphere

polar easterlies

prevailing winds that blow from east to west between 60 degrees to 90 degrees latitude in both hemispheres

Prevailing easterlies

prevailing winds that blow from 30 degrees and 60 degrees latitude some of the desending air moving toward the poles is deflected by the coriolis effect

trade winds

prevailing winds that blow from 30 degrees to 0 degrees in both hemispheres that blow from east to west

doldrums

trade wind system of the northern and southern hemisphere meet at the equator in a narrow zone

air mass

a large body of air that takes on the characteristics of the area over which it forms

land breeze

is formed when the land surface cools down faster than the water surface

sea breeze

is formed by water heating up slower than the land

warm front

the transition zone where a warm air mass is replacing a cold air mass

cold front

a zone seperating two air masses of which the cooler, denser mass is advancing and replacing the warmer air

stationary front

is the boundary between two air masses that neither of which is replacing

occluded front

occurs when a cold front eventually cathches up to warm front and collide to form

high pressure system

region when the atmospheric pressure and the surface is greater than the enviroment

low pressure system

is when the barometric pressure is lower than the surrounding area
