Climatology is the scientific study of climate, defined as the long‑term patterns of temperature, precipitation, wind, and other atmospheric conditions over a region or the entire planet. It focuses on the analysis of climate variability and change over time scales that range from years to millennia. Climatologists use extensive data sets, including surface observations, aerial and satellite remote sensing, and paleoclimate proxies such as tree rings, ice cores, and sediment layers, to reconstruct past climate states and to identify natural and anthropogenic drivers of change.

Key subfields include atmospheric climatology, which examines pressure systems, moisture transport, and large‑scale circulation patterns; oceanic climatology, which studies sea‑surface temperature, salinity, and currents; and cryospheric climatology, which focuses on the dynamics of ice sheets, glaciers, and permafrost. Climate dynamics involves the study of ocean‑atmosphere interactions, such as El Niño–Southern Oscillation, the Gulf Stream, and the polar vortex. Paleoclimatology reconstructs past climates to understand natural cycles like the Milankovitch variations and volcanic influences. Climate change science quantifies human impacts, particularly greenhouse‑gas emissions, and models their consequences for future temperature, sea‑level rise, and extreme event frequency.

Climatology informs policy and adaptation strategies by providing climate projections, vulnerability assessments, and mitigation pathways. It interfaces with related disciplines such as meteorology, which deals with shorter‑term weather forecasting, and environmental science, which integrates biophysical process understanding across ecosystems. Together, these fields foster a comprehensive approach to managing the risks and opportunities posed by changing climatic conditions worldwide.
