Climatology is the scientific study of the Earth's climate, typically defined as weather conditions averaged over a period of at least 30 years. It focuses on recording and analyzing weather patterns over time, as well as understanding the impacts of climate on society, infrastructure, and natural systems. Climatologists study the causes of climate change, the nature of climates (local, regional, or global), and the factors that influence climate change, such as atmospheric conditions, oceanic circulation, and land surface interactions
. It is a branch of the atmospheric sciences that encompasses various subdisciplines, including dynamic meteorology, paleoclimatology, and bioclimatology
