  2. 2.  Climatology is the study of climate, scientifically  defined as weather conditions averaged over a  period of time. This modern field of study is  regarded as a branch of the atmospheric  sciences and a subfield of physical geography,  which is one of the earth sciences. Climatology  now includes aspects of oceanography  and biogeochemistry.
