Geography & atmospheric sciences

Mathematical tools, such as differential equations and vector analysisand computer systems are used to evaluate the physical and chemical relations that describe the workings of the atmosphere. The atmospheric sciences are traditionally divided into three topical areas— meteorology the study and forecasting of weatherclimatology the study of long-term atmospheric patterns and their influencesand aeronomy the study of the physics and chemistry of the upper atmosphere.

In meteorology, the focus of study concerns day-to-day and hour-to-hour changes in weather within the lower stratosphere and troposphere.

Climatology, on the other hand, concentrates more on longer time periods ranging from a single month to millions of years and attempts to describe the interaction of the atmosphere with the oceans, lakes, land, and glaciers. For example, of the three topical areas, climatology would be the best equipped to provide a farmer with the most likely date of the first frost in the autumn.

The focus of aeronomy is on the atmosphere from the stratosphere outward. This field also considers the role the atmosphere plays in the propagation of electromagnetic communications, such as shortwave radio transmissions. Within these three major topical areas, the broad nature of the atmospheric sciences has spawned practitioners who specialize in several distinct subfields.

Scientists who investigate the physics associated with atmospheric flow are called dynamic meteorologists or simply dynamicists. When the investigation procedure involves the application of large computer models of atmospheric structure and dynamics, the scientists are called numerical modelers. Scientists and technicians who specifically investigate procedures of weather forecasting are called synoptic meteorologists, while those who investigate the physical mechanisms associated with the growth of cloud droplets and ice crystals and related precipitation processes are called cloud physicists.

Researchers who study atmospheric optical effects are referred to as physical meteorologists, while individuals who investigate the dynamics and observations of climate are called climatologists or climate scientists.

Paleoclimatologists are researchers who concentrate on ancient climate patterns. Atmospheric science. Article Media. Info Print Cite. Submit Feedback. Thank you for your feedback. Written By: Roger A. See Article History.

February 10, Atmospheric physics Atmospheric dynamics category. Climate category Climate change category. Atmospheric science is the study of the Earth's atmosphere and its various inner-working physical processes. Meteorology includes atmospheric chemistry and atmospheric physics with a major focus on weather forecasting. Climatology is the study of atmospheric changes both long and short-term that define average climates and their change over time, due to both natural and anthropogenic climate variability.

Aeronomy is the study of the upper layers of the atmosphere, where dissociation and ionization are important. Atmospheric science has been extended to the field of planetary science and the study of the atmospheres of the planets and natural satellites of the solar system.

Experimental instruments used in atmospheric science include satellitesrocketsondesradiosondesweather balloonsand lasers. Atmospheric chemistry is a branch of atmospheric science in which the chemistry of the Earth's atmosphere and that of other planets is studied.

It is a multidisciplinary field of research and draws on environmental chemistry, physics, meteorology, computer modeling, oceanography, geology and volcanology and other disciplines. Research is increasingly connected with other areas of study such as climatology. The composition and chemistry of the atmosphere is of importance for several reasons, but primarily because of the interactions between the atmosphere and living organisms.

The composition of the Earth's atmosphere has been changed by human activity and some of these changes are harmful to human health, crops and ecosystems. Examples of problems which have been addressed by atmospheric chemistry include acid rain, photochemical smog and global warming.

Atmospheric chemistry seeks to understand the causes of these problems, and by obtaining a theoretical understanding of them, allow possible solutions to be tested and the effects of changes in government policy evaluated.

Atmospheric dynamics is the study of motion systems of meteorological importance, integrating observations at multiple locations and times and theories.

Common topics studied include diverse phenomena such as thunderstormstornadoesgravity wavestropical cyclonesextratropical cyclonesjet streamsand global-scale circulations. The goal of dynamical studies is to explain the observed circulations on the basis of fundamental principles from physics.

The objectives of such studies incorporate improving weather forecastingdeveloping methods for predicting seasonal and interannual climate fluctuations, and understanding the implications of human-induced perturbations e.

Atmospheric physics is the application of physics to the study of the atmosphere. Atmospheric physicists attempt to model Earth's atmosphere and the atmospheres of the other planets using fluid flow equations, chemical models, radiation balancing, and energy transfer processes in the atmosphere and underlying oceans. In order to model weather systems, atmospheric physicists employ elements of scattering theory, wave propagation models, cloud physicsstatistical mechanics and spatial statisticseach of which incorporate high levels of mathematics and physics.

Atmospheric physics has close links to meteorology and climatology and also covers the design and construction of instruments for studying the atmosphere and the interpretation of the data they provide, including remote sensing instruments. In the United Kingdom, atmospheric studies are underpinned by the Meteorological Office. Divisions of the U. The U. National Astronomy and Ionosphere Center also carries out studies of the high atmosphere. The Earth's magnetic field and the solar wind interact with the atmosphere, creating the ionosphereVan Allen radiation beltstelluric currentsand radiant energy.

In contrast to meteorologywhich studies short term weather systems lasting up to a few weeks, climatology studies the frequency and trends of those systems. It studies the periodicity of weather events over years to millennia, as well as changes in long-term average weather patterns, in relation to atmospheric conditions.

Climatology considers the past and can help predict future climate change. Phenomena of climatological interest include the atmospheric boundary layercirculation patternsheat transfer radiativeconvective and latentinteractions between the atmosphere and the oceans and land surface particularly vegetationland use and topographyand the chemical and physical composition of the atmosphere.

All of the Solar System's planets have atmospheres. This is because their gravity is strong enough to keep gaseous particles close to the surface.

Larger gas giants are massive enough to keep large amounts of the light gases hydrogen and helium close by, while the smaller planets lose these gases into space. There is a thin atmosphere on Tritonand a trace of an atmosphere on the Moon. Planetary atmospheres are affected by the varying degrees of energy received from either the Sun or their interiors, leading to the formation of dynamic weather systems such as hurricaneson Earthplanet-wide dust storms on Marsan Earth-sized anticyclone on Jupiter called the Great Red Spotand holes in the atmosphere on Neptune.

Hot Jupiters have been shown to be losing their atmospheres into space due to stellar radiation, much like the tails of comets.A culture of research excellence and scholarly achievement with numerous M.
