The weather undergoes constant changes, which can be very noticeable not only from one day to the next, but even within a few minutes. Weather changes are periodic and non-periodic. Periodic changes are called those changes that are periodic in nature, since they are associated with the rotation of the Earth around its axis (daily changes) or around the Sun (annual changes). The most noticeable are daily changes directly at the earth's surface, due to the fact that they are determined by changes in the temperature of the earth's surface, and other meteorological elements are associated with air temperature. Annual changes are expressed in the change of seasons.
