We denominate climate to the totality of atmospheric conditions proper of a specific place of the planet, measured during a certain time. These atmospheric conditions are the temperature, the intensity of the rain, the humidity, the intensity and direction of the wind, the atmospheric pressure, among other factors. The interaction of all these factors exerts a great influence on the life forms of all the beings subjected to that climate, be they plants, animals and the human being. The climate exists as long as the atmospheric factors vary and it is possible that they are measured and compared in scales of time to know that they repeat with certain continuity and constitute a more or less stable pattern.
The distance that a place on earth has from the equator affects the climate as we approach the poles. The conditions vary in that range because the planet has an inclination in its turn with respect to the sun, due to this, the rays of the sun hit the surface of the terrestrial globe in irregular form, with greater incidence among the tropics.
