ELEMENTS OF THE CLIMATE

1. ELEMENTS OF THE CLIMATE

2. INTRODUCCTION
 In this article I will talk about how it influences
atmospheric pressure and wind climate. The factors of
the atmospheric pressure are the average pressure,
altitude and air temperature. And also I will discuss
the factors of the wind.

3. ATMOSPHERIC PRESSURE
The atmospheric pressure is the weight of a
column of air on a place is measured with a
barometer and is expressed as millibars
(mb).
The average pressure is measured at sea level.
The areas with a pressure higher than the
average are anticyclones (A) and the areas of
lower pressure are depressions (B).

4. DIFFERENTS IN PRESSURE
increase in altitude.
-Air temperature: warm air is less, dense and
lighter so its tends to rise. This produces low
pressure and precipitations, cold air is denser and
heavier, so its tends to fall. Its produces: high
pressure or an anticyclone.
·Equator: permanent low pressure.
·Tropics and Poles: permanent high pressure.
·Temperate zones: high and low pressure alternates.

5. WIND
 Wind is the horizontal
movement of air, it is
measured with the
anemometer and its
direction is measured
with the weather vane
that is based on the
cardinal point of the
source of the wind.
 The factor that causes the
wind is the difference in
atmospheric pressure, the
wind always blows from
areas of high pressure
towards areas of low
pressure.

6. MOST IMPORTANT WINDS
 On the Earth, there are constant winds that transport
hot air towards the cold zones and vice versa,
maintaining equilibrium temperatures. The most
important winds are:
-Trade winds
-West winds
-Polar winds

7. Can you tell me
what types of
currents see in
these images?
Tell me what ways
have the cold
currents and forms
the warm.
