Foreword

If you google for "climate", you will be forwarded to the general Wikipedia page presenting an overview of the climate system of our planet Earth. Before quoting the proposed definition, few etymological notes. The origin of the word is the greek klima, that comes from the verb klino, meaning "to tilt" or to give a slope to something; so the term was used, by ancient geographers, to divide the earth into zones characterized by the angle (usually measured at noon, during the solstice) of the sun on the earth's surface.
Sun height is strictly related to daylight duration and solar input, that influences the air temperature, the movement of winds etc, so the idea of geographical climate as "solar height" slowly assumed the meaning of average "temperature", "weather" and its progressive change from one place to another. But the weather (and our personal feeling about it or the answer to it from specific anthropic activities, agriculture, first) is not only influenced by solar height and you may have, at the same latitude very different ... climates or, viceversa, you can have more or less the same climatic conditions in very different places in the world: «The sense shift to "combined results of weather associated with a region, characteristic condition of a country or region with reference to the variation of heat, cold, rainfall, wind, etc." is attested by c. 1600» [Eymonline].
