Making a weather station
and recording what is happening with the elements isn't very difficult.
It gets much harder when it comes to predictions: even the experts with
their weather wizardry get it wrong sometimes.
The sun is the driving
force behind the weather. As solar energy reaches the earth, equatorial
regions heat up more than the poles. In addition to this, the rotation
of the Earth and its path around the Sun are always modifying this heating
effect. Due to convection
warm air and water at the equator travel towards the poles while cold
air and water at the poles travel towards the equator. It is the atmosphere's
continual stirring due to convection and rotation that creates and brings
to us our changing weather.
