Air
Two aspects are at the centre of the section on “AIR“ : the different states of air at a particular location and at a particular time describe basically what we call “weather“. The overall behaviour of air masses in atmospheric circulation regulate the climate of the Earth and its regions.
Prior to following a “parcel of air“ on its way into the atmosphere, you can spare a thought or two for the medium of air. Air is a part of us, our breath links us with this element. Air can be weighed, and we can describe the state of air with various data. Your parcel of air begins to move, first as a ground wind, then in the form of typical wind masses. The parcel of air continues rising even higher, and it gives you a new perspective so that ultimately you can make out the entire atmospheric circulation. In the process, it becomes evident that the apparently chaotic movements of winds, fronts and currents are part of a greater pattern that creates our climate.
