solar energy water cycle atmospheric pression.
The temperature depends on solar energy.Generally you use the maximum temperature
and minimum temperature to determine the range.
It is the difference between the lowest and the highest temperature in a 24 hours period.
It is the quantity of the water steam in the air.This steam, when it condenses , makes the clouds.Clouds are different for shape.The condensation can form:- mist, during the night;-dew, when condensation is by the ground;- hoar-frost, when the temperature decreases
quickly.
When the clouds reaches big size, they fall down in the form of rain, snow and hail.
If they fall down in the form of water, it rains.If they fall down in the form of ice, snow or hail.
It is constituted by weight of the air.It is maximum at the level of the sea.The pressure depends on the temperature then it isn’t
everywhere always the same.When it is higher there are high-pressure areas.When it is lower there are the low-pressure areas.
Winds are draughts of air, that it moves and it makes two mass of different pressure.
The winds’ direction is signal by weathercock.The winds’ speed is measured in m/sec or km/h.The main Italian winds are:

The hydroelectric power stations are classified in:
Mountain stationPlain station
The station of plane is composed bydam and central.
The station of mountain is composed by:
Artificial basin, formed by a dam;
Piping, that is divided in: channel of derivation and forced duct;
Central, placed on slope.
