Meteorology, climatology, atmospheric physics, and atmospheric chemistry are sub-disciplines of the atmospheric sciences. Pyrgeometers are frequently used in meteorology, climatology studies. Global scale meteorology pushes into the range of climatology. This calculation is useful in astronomy, navigation, surveying, meteorology, climatology, solar energy, and sundial design. Includes instruction in biology, chemistry, physics, geosciences, climatology, statistics, and mathematical modeling. Other studies include actinometry, geophysics, medicine and climatology. In 1986 he won the Balzan Prize for Oceanography/Climatology. Various subfields of climatology study different aspects of the climate. Researchers will utilize Summit for diverse fields such as cosmology, medicine and climatology. Several other research projects, mostly pertaining to geography and climatology, are carried out less regularly. For purposes such as tornado climatology studies, Fujita scale ratings may be grouped into classes. The National Institute of Physical Climatology and its observatory are also in the Prado. Abraham became a professor of climatology at Princeton University. Research is increasingly connected with other areas of study such as climatology. The vegetation around Granada is a reflection of its climatology.
