ch28.1 Flashcards
trophosphere
where weather takes 12 km above earths surface
temperature inversion
occurs when air temperature increases with altitude and air becomes stable
the greenhouse effect
is a natural process in which certain gasses in the atmosphere warm the planet as they absorb and emit inferred radiation
with in the mesosphere does the temperature increase or decrease with altitude
decreasing
does the thermosphere and exosphere effect weather
no
how much solor radiation is absorbed by earths surface
5o percent
what percent of radiation is reflected off the surface
5 percent
what percent of radiation is absorbed by particles in the atmosphere
20 percent
what percent of radiation is reflected by clouds
25 percent
what are the three basic cloud types
stratus,cumulus and cirrus
describe stratus clouds
layerd sheet like clouds
describe cumulus clouds
puffy
describe cirrus clouds
whispy at high altitudes
jet stream
a narrow band of fast moving high altitude wind
coriolis effect
deflection of amn object due to earths rotation
air mass
a large volume of air without uniform
weather fronts
where air masses interact
how many jet streams are in the world
4
how many pressure systems are there
2
what is a low pressure system also known as
L
what are some results of a low pressure system
cloud formation and percipitation
what is a high pressure system known as
H
which way does a high pressure system rotate
clockwise
what are the results in a high pressure system
the air sinks and causes a clear sky
