What is the climate ?

The word climate, from the ancient Greek “ klima “, is commonly understood as the pattern average and variations of weather in a precise region, for the duration of a relatively long observation period.
To build that image, some parameters are considered, such as temperature, wind and precipitation.
Such data, collected over a standard period ( not less significant than 30 years, but other periods may be used depending on the purpose ), allow us to be aware of local meteorological reality and define it according to precise models. There are in fact a few climate zones, which are common to several different regions around the planet.
To define the local climate, also statistics other than the average, such as the magnitudes of day-to-day or year-to-year variations, are also considered.
The Intergovernmental Panel on Climate Change ( ) glossary definition is :

Climate in a narrow sense is usually defined as the “ average weather ”, or more rigorously, as the statistical description in terms of the mean and variability of relevant quantities over a period of time ranging from months to thousands or millions of years. The classical period is 30 years, as defined by the World Meteorological Organization ( WMO ).
These quantities are most often surface variables such as temperature, precipitation, and wind. Climate in a wider sense is the state, including a statistical description, of the climate system.

What are climate zones ?

As above mentioned, it is possible to recognize the local climate according to a precise model or standard.
There are a few different ways according which climate types have been defined so far.
At the present time, climate zones can be defined more generally under the Köppen climate zones classification, used by geography, climatology and ecology. When considering such system, keep in mind that there are usually gradual transitions from zone to zone.
The clime zones were developed in 1900 by a German climatologist, Wladimir Köppen, and later, in collaboration with Rudolf Geiger, were improved several times until 1936.

Köppen-Geiger climate zones

Climate zones are limited by parameters such as temperature and rainfall according to a year round evolution.
