Rain is the most common type of atmospheric precipitation and it happens when separate drops of water fall from the clouds to the ground. The rain plays a very important role in the water cycle. Water evaporates from the oceans, condenses in the clouds and falls to the ground, then it returns to the ocean through groundwater and rivers, thus repeating the cycle. In this way water becomes available to the biosphere, allowing the development of flora and fauna and becoming available for human beings.

Clouds are made by verylittle water particles, ice crystals or both of them. They are suspended in the athmosphere and they do not usually touch the ground.
We gauged atmospheric pressure with a barometer!
Atmosphere is composed by a mixture of gases, one of which is water vapour. Water vapour is added to atmosphere by evaporation and transpiration and it is removed when it condenses or when it freezes and crashes.
Relative humidity (RH) is the ratio between water vapour’s quantity in the atmosphere and the maximum possible one at the same temperature.
Absolute humidity is the water vapour’s quantity in the atmosphere.
Temperature is the physical quantity that indicates body or system’s thermal state.
For maximum temperature
For minimum temperature
For actual temperature
We report the 3 temperatures then we press the key “clear” every day to reset data just wrote.
Wind is an horizontal movement of air masses as a result of the vertical movements of atmospheric air masses.
Our “little house”. Inside it there are our instrument!
We are watching the clouds...
We are wathing wind direction and then we write data on Globe’s scheemes.
