Climatology

climatology, connects physical geography, is the study of , i.e. succession of the weather conditions over long periods in time. The study of short-term time is the field of .

In general, the climate does not vary, or rather little, in a given place of the sphere, over one duration of the scale of . But over geological times, the climate can change considerably. For example, Scandinavia knew several ice ages in the last million years. The study of the last climates is paleoclimatology. This study according to the human history is called historical climatology.

Climatology is based on historical statements meteolorogic, as on measurements raised by artificial satellite, but also the thickness of the snow cover, retreat of the glaciers, chemical analysis of the air imprisoned in the ice, etc.

The knowledge of many parameters, like the temperature at various altitudes, the influence of , the relative humidity, oceanic evaporation, is necessary to produce numerical climatic models and to anticipate the changes of the climate which one can provide in the more or less long term.
