Abstract

Planet Earth is essentially made up of a solid whole which, on a time scale of the order of a year, a century, or even a millennium, shows little change, except for volcanic or seismic manifestations, and here and there, a few superficial and local movements. This set is overcome by fluid envelopes: the hydrosphere (liquid and discontinuous) and the atmosphere (gaseous and continuous). These envelopes are very mobile and subject to movements, which can be very rapid and very inconstant with regard to the atmosphere. They are mainly, but not only, the place of development of living beings, which partly explains the interest we have in them. The study of the short-term variation of atmospheric parameters (such as temperature, pressure, winds, cloud cover, precipitation, etc.), and the forecasting of this variation, is the subject of meteorology (from the Greek meteos, high in the air). ...
