The
polar
climate
is
located
in
latitudes
between 65º
and 75º north
the equator. It
is located on
North
of
Canada,
Northern
Europe,
Northern
Russia and in
the Antarctica.
This type of climate
characterizes for having
short and cool summers,
with very long days and
average
temperatures
that don’t pass 10ºC.
Instead winters are very
long and very cold, there
are very few hours of day
and average temperatures
of -20ºC. Some days of
summer have 24h of light
and of winter 24h of night.
The temperature range is
quite big of 50ºC
Precipitations are very
scarce of 200-300mm
a year and when they
fall they do it in form
of snow.
This occurs because
the air is too cold for
holding any moisture.
Alpine
climates are
located
all
around
the
world at high
altitudes. Such
as for example
in
the
Himalayas, the
alps,
the
The Alpine climates have
very cold temperatures all
around the year due to
the high altitudes.
These temperatures vary
a lot as you go up. For
every
1000m
temperatures
descend
6.5ºC.
So we can say that
Precipitations
also
depend of altitude
because as rising the
air is colder and so it
cannot trap a lot of
moisture.
Normally
these precipitations
are of 3000mm a year
and occur in form of
snow.
These regions are covered
with perpetual ice. So very
few plants can survive. We
called this landscape
Tundra in which the soil is
always frozen. Tundra
landscapes characterises
for having no trees, very
small shrubs, bushes and
heather. However the
most abundant thing is
grass that in spring
flourishes. We find that
under
south
tundra
landscapes we can always
find dense coniferous
forests.
Alpine vegetation also
varies with altitude. We
find with 5 layers: 1 layer
has coniferous trees,
shrubs and herbaceous
plants. The second layer
has: more shrubs and less
trees. The 3 has: Scarce
trees, less shrubs and
more herbaceous plants.

These plants normally
have spiny leaves. Some
examples of plants found
in cold deserts include
grasses and cacti.
