Atmospheric science is a broad field of scientific knowledge that includes a number of sub-disciplines that study the phenomena and processes found in the atmosphere of Earth and even other planets. Atmospheric science includes the sub-disciplines of meteorology, climatology, atmospheric chemistry, and atmospheric physics. Atmospheric scientists often study how the phenomena and processes found in other systems, including the lithosphere, biosphere, hydrosphere, and cryosphere, interact dynamically with the atmosphere.

During the 20th century, Earth's globally averaged surface temperature rose by approximately 1.08°F (0.6°C). Additional warming of more than 0.25°F (0.14°C) has been measured since 2000. Though the total increase may seem small, it... More »

Cleveland, and Laura De Angelo. In the interests of maintaining scientific accuracy, this article is derived directly from material in the Synthesis Report and the Technical Summary of Working Group I, "The Physical Science Basis," of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). The full Synthesis Report and Technical Summary are reproduced in this Encyclopedia, and are available in their original PDF forms at the IPCC web site. The relevant IPCC Lead Authors are listed in the Acknowledgments at the end of this article. Climate change refers to a change in the state of the climate that can be identified by changes in the average and/or the variability of its properties (e.g., temperature, precipitation), and that persists for an extended...

Cumulus panoramaflagstaffotos.jpg Meteorology (Atmospheric Science) Last Updated on 2014-10-26 16:32:04 Meteorology is the scientific study of the atmosphere and physical processes of interaction with the Earth's crust, oceans and outer space. Meteorological phenomena are observable weather events which are investigated by the science of meteorology. The chief parameters comprised by the science of meteorology are: temperature, barometric pressure, humidity, sunlight and the gradients and interactions of each variable, as well as their temporal variability. The majority of Earth's observed weather is located in the troposphere. Different spatial scales are studied to determine how systems on local, regional, and global levels impact meteorological phenomena. Meteorology, climatology, atmospheric physics and atmospheric chemistry are sub-disciplines of the atmospheric sciences. Meteorology and hydrology compose the interdisciplinary field of hydrometeorology. Interactions... More »
Climateleadimage1321141778.PNG.jpeg Climate (Atmospheric Science) Last Updated on 2014-10-01 10:48:54 Climate is the typical pattern of conditions of the earth’s atmosphere over a given region, as defined by factors such as temperature, air pressure. humidity, precipitation, sunlight, cloudiness, and winds. The World Meteorological Organization defines climate as "the statistical description in terms of the mean and variability of relevant quantities over a period of time," where an appropriate period is typically at leastthirty years.Climate can be assessed at different, overlapping geographic regions. For example, Earth is thought to have a climate that is distinct from that of other planets, while different regions of Earth are also thought to have distinct climate types. Climate is often described as the "average" conditions; however, since daily and seasonal variability (including extremes) are critical determinants, using the term... More »
