Whether you’re surveying regional climate risks for agriculture or tracking urban heat islands, a clear map of the field helps you ask the right questions and find relevant data. Different users—researchers, planners, students—tap into distinct climatology subfields depending on the problem and scale.
There are 18 Branches of Climatology, ranging from Agroclimatology to Urban climatology. For each branch you’ll find below data organized with the columns Timescale (yrs),Spatial scope,Core focus & methods to help compare what each studies and how it gathers evidence, so you can quickly see where a topic fits and which methods apply—you’ll find below.
How do these branches differ in the kinds of data and methods they use?
Branches vary mainly by temporal and spatial resolution and by core techniques: some (e.g., paleoclimatology) rely on proxies and long-term reconstructions, others (e.g., synoptic climatology) use weather observations and pattern analysis, and applied fields like agroclimatology combine climate records with crop models and soil data.
Which branch is most useful for local climate adaptation planning?
For local adaptation, urban climatology and microclimatology are often the most directly applicable because they focus on fine spatial scales and interventions; however, integrating insights from regional climatology and climate change impacts yields better risk assessments and longer-term strategies.

Images and Descriptions
Physical climatology
Studies how atmospheric energy, radiation, heat transport and feedbacks govern climate. Uses theory, observations and simple models to explain temperature patterns, radiative forcing, and processes that set mean climate and climate sensitivity across regions and decades.
Climate dynamics
Focuses on large-scale processes that drive climate variability and change, including circulation, waves, and feedbacks. Employs analytic theory and dynamical models to understand how the climate system evolves on seasonal to millennial timescales.
Synoptic climatology
Examines how recurring weather systems and atmospheric patterns influence local and regional climate statistics. Uses weather maps, composites and reanalysis to link synoptic regimes with temperature, precipitation, and extremes over days to seasons.
Paleoclimatology
Reconstructs past climates using proxies like ice cores, tree rings, sediments and corals to extend climate records beyond instruments. Helps understand natural variability, past greenhouse climates, and baseline conditions for evaluating recent changes over centuries to millions of years.
Historical climatology
Uses written records, ship logs, and early instruments to reconstruct past weather and climate over centuries. Connects human history and climate impacts, validating proxies and informing long-term variability and societal vulnerability assessments.
Regional climatology
Describes climate characteristics of specific regions, combining observations, local models, and downscaling. Useful for water management, agriculture, and regional planning by translating broad climate signals into local expectations over decades.
Microclimatology
Studies small-scale atmospheric conditions near the ground—within forests, urban canyons, or agricultural fields. Focuses on temperature gradients, humidity, and radiation at fine spatial scales, informing habitat studies, microhabitat assessments, and local adaptation measures.
Urban climatology
Investigates how cities alter climate through surfaces, emissions, and ventilation. Uses observations and urban models to study heat islands, air quality interactions, and mitigation strategies for public health and urban design across seasons and decades.
Agroclimatology
Applies climate science to agriculture: planting dates, yield risks, drought frequency, and seasonality. Uses climate records and models to guide farmers, insurers, and policymakers on adaptation and food security at seasonal to interannual scales.
Hydroclimatology
Explores links between climate variability and the hydrological cycle, including rainfall patterns, floods, and droughts. Integrates climate data, hydrologic models, and river observations to inform water resources and risk management.
Cryoclimatology
Studies climate interactions with ice sheets, glaciers, sea ice and permafrost. Uses field observations, satellites, and models to assess ice response to warming, sea-level contributions, and feedbacks important on decadal to millennial timescales.
Atmospheric chemical climatology
Examines how atmospheric composition (CO2, methane, aerosols, ozone) interacts with climate. Combines measurements, chemistry-transport and climate models to study radiative forcing, air-quality links, and long-term composition trends.
Bioclimatology
Studies how climate affects living organisms and ecosystems—phenology, species ranges, and physiological responses. Uses experiments, observational networks and models to project ecological impacts of climate variability and change.
Statistical climatology
Develops and applies statistical tools to detect trends, quantify variability, and analyze extremes in climate data. Uses advanced statistics and data science to interpret observations, create indices, and support attribution and projection studies.
Climate modeling
Builds and uses numerical climate models to simulate past, present and future climates. Central to projecting climate change, testing hypotheses about forcings and feedbacks, and producing scenarios for impact assessment and policy.
Detection and attribution
Focuses on identifying human and natural causes of observed climate changes. Combines observations, models and statistical methods to attribute trends and extremes to greenhouse gases, aerosols, or natural variability, informing policy and legal questions.
Extreme event climatology
Studies statistics, trends and drivers of heavy rainfall, heatwaves, storms and compound events. Uses observations, reanalysis, and models to assess risk, detect changes, and inform emergency planning and infrastructure design.
Climate services
Bridges climate science and users by producing tailored information for decision-making—seasonal forecasts, risk assessments, and adaptation advice. Combines science, communication, and co-production to support health, agriculture, water and urban planning.
