adiabatic heating/cooling
results from change in pressurenot by addition/removal of heat energy
cold air (2)
most dense
holds less moisture than warm air
lapse rate
rate that the rising air mass cools
depends on dryness/wetness
wind is named by
where they're coming from
rotating Earth's wind cells
Hadley cell
Ferrel cell
Polar cell
intertropical convergent zone (ITCZ)
convergence between NE and SE trade winds
hourse latitudes
divergence between NE trades and westerlies
polar front
polar jet strem is located
convergence between westerlies and polar easterlies
low pressure
tropopause
troposphere and stratosphere
polar jet develops at
40 degree altitude
difference between climate and weather
climate
: the average of years of data. world wide
weather
: day by day. local
5 subsystems that affect the weather
lithosphere
: human activity
cryosphere
: snow and glacier ice
hydrosphere
: heat, evaporation
atmosphere
: heat
biosphere
: CO2
geological records of climate comes from
fossil evidence
oxygen isotope
peaks
: low ice volume, interglacial, warm temperature
valleys
: high ice volume, glacial, cold temperature
ice core
higher value
: warmer temperature
lower value
: colder temperature
why climate change (external forcing) (2)
sunspot cycle
: 11 year intervals
orbital/astronomical factors
: wobble and tilt
why climates change (internal forcing) (3)
atmospheric filtering
: how much radiation reaches the Earth
volcanic activity
changes in ocean circulation
Medieval Climate Anomaly
regional (Europe)
900-1300 AD
peak in solar activity
The Little Ice Age
1300-1850
The warm middle cretaceous
no glaciers
higher sea level
higher CO2 level
epicontinental seaway
splitting the continent in half
