Climatology is the study of the myriad factors that influence weather, and the influence of weather on the environment. These include water, atmosphere, and geology. Climatology studies all of these things over the course of time, typically a 30 year cycle.
Data sets formed from the long-term average of historical weather parameters are sometimes called a climatology. Climatology is approached in a variety of ways. Paleoclimatology seeks to reconstruct past climates by examining records such as ice cores and tree rings (dendroclimatology).
