winds that blow without friction are called
geostrophic
high pressure is associated with
divergence
on the earths surface this is the place where westerlies collide with
polar easterlies
polar front
the speed of wind is associated with
pressure gradient
in the % above equation , the value 5.6 tell us that
for every 5.6 km we move , we loose half our previous pressure
the deflection of wind case by the earths rotation is greatest at
the AND
MINIMAL AT THE
the poles , the equator
large spacing between isobars wind speed and small
between isobars
wind speed
decrease : increases
in what two directions does wind travel in a low pressure system ?
up and counterclockwise
another name for win driven , surface currents
gyres
moving towards the center of a low pressure cell , air pressure will
decrease
a change in pressure over a change in distance , is the equatin for
pressure gradient force
as the sub solar fluctuates into the northern hemisphere, what below
is not true
the ITCZ has dropped into the southern hemisphere
at high elevations, this is the where westerlies collide with polar easterlies
Polar jet stream
what time of year is repeated below
ANY equinox
low pressure is most associated with
convergence
in what two directions does wind travel in high pressure system
down and clockwise
according to our book , this is another name for southern oscillating currents
el nino
relatively calm winds found within the itcz are called
doldrums
why is the height of the 500 mb isobar at the equator and lower at
the poles
the poles are colder than the equator
which colum of air has higher pressure aloft
B
which colum has the highest surface pressure
A
the pressure gradient force would be from
B to A
during convection surface winds would blow from
A to B
percentage of atmosphere above you
57%
the air pressure one could expect at elevation
566mb
what is the partial pressure of oxygen
118.86
these are the dominant winds found between 0 and 30 north and south
trade winds
these are the dominant winds found between 30 and 60 north and south
westerlies
these are the dominant winds found between 60 and 90 north and south
polar easterlies
this is the theoretical pressure belt found around 30 north and south
sub tropical high
this is theoretical pressure belt found around 60 north and south
sub polar low
this is the theoretical pressure belt found around the poles north
and south
polar high
this is convective cell found between 0 and 30 north and south
Hadley cell
this is the convective cell found between 30 and 60 north and south
ferrel cell
this is the convective cell found between 60 and 90 north and south
polar cell
calm/dead winds found within the ITCZ
doldrums
air pressure changes slowly over surface air
warm
air density , air stability , and density share what common dependant factor
temperature
which of these does not separate warm air and cold air
ITCZ
in the northern hempisphere , the coriolis effect pulls wind to the
of travel
right
fluctuations in the ITCZ are caused by
changes in the sub solar point postion
where is the starting point of "the great converyor"?
Atlantic
upper level divergence of air creates what kind of surface pressure
low
the earth has " pressure cells " and not "belts"
because of the influence of
land
another name for cold, deep water currents
thermohaline
clockwise out spirals of wind are generally associated with
high pressure
deflection caused by the earths rotation
coriolis effect
if a parcel of air has a saturation vapor pressure of 2.6 mb yet the
force it exerts is only 4.8 mb , what does that tell you about the air ?
it is unsaturated
warm surface temperatures create pressure aloft
high
air pressure changes more rapidly over a surface
humid
