meteorology Flashcards
trophosphere
the lowest level of the atmosphere, where all weather takes place. most of the air surrounding the Earth is found here
stratosphere
above the troposphere, air flow here is mostly horizontal. primarily responsible for for absorbing ultraviolet radiation from the sun
ozone layer
the upper stratosphere that has a high concentration of ozone, a particularly reactive form of oxygen
mesosphere
extends to about 90 kilometers above earth. this is where we “falling stars”
thermosphere
temps here increase because there’s little matter to deflect solar radiation
stationary front
sometimes 2 air masses meet and neither is displaced, instead the 2 push together in a stalemate. stationary fronts can often cause cloudy, wet weather that can last a week or more
how many types of clouds are there?
3
stratus clouds
low hanging, broad, flat clouds that blanket the sky. when they occur on the ground its called fog.
cumulus clouds
clouds that are puffy, like popcorn, with mostly flat bottoms and rounded tops. heavy rain happens when they darken
cirrus clouds
clouds that are thin, wispy clouds that occur much higher in the atmosphere at elevations of 20000 feet or more
