1Atmospheric electricity — is the regular diurnal variations of the Earth s atmospheric electromagnetic network (or, more broadly, any planet s electrical system in its layer of gases). The Earth’s surface, the ionosphere, and the atmosphere is known as the global… …
2Atmospheric reentry — refers to the movement of human made or natural objects as they enter the atmosphere of a planet from outer space, in the case of Earth from an altitude above the edge of space. This article primarily addresses the process of controlled reentry… …
3Atmospheric convection — Conditions favorable for thunderstorm types and complexes Atmospheric convection is the result of a parcel environment instability, or temperature difference, layer in the atmosphere. Different lapse rates within dry and moist air lead to… …
4Atmospheric dispersion modeling — Industrial air pollution source Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that solve the mathematical equations and algorithms… …
5Compilation of atmospheric dispersion models — Atmospheric dispersion models are computer programs that use mathematical algorithms to simulate how pollutants in the ambient atmosphere disperse and, in some cases, how they react in the atmosphere. The dispersion models are used to estimate or …
6Current sea level rise — This article is about the current and future rise in sea level associated with global warming. For sea level changes in Earth s history, see Sea level#Changes through geologic time. Sea level measurements from 23 long tide gauge records in… …
7Before Present — (BP) years are a time scale used in archaeology, geology, and other scientific disciplines to specify when events in the past occurred. Because the present time changes, standard practice is to use 1950 as the arbitrary origin of the age scale.… …
8sea level — the horizontal plane or level corresponding to the surface of the sea at mean level between high and low tide. [1800 10] * * * Position of the air sea boundary, to which all terrestrial elevations and submarine depths are referred. The sea level… …
9Sea level rise — is an increase in sea level. Multiple complex factors may influence this change. Sea level has risen about 130 meters (400 ft) since the peak of the last ice age about 18,000 years ago. Most of the rise occurred before 6,000 years ago. From 3,000 …
10List of Maryland hurricanes (1980–present) — List of Maryland and Washington, D.C. hurricanes from 1980 ndash;present encompasses 54 known hurricanes, tropical storms and tropical depressions that have affected the U.S. state of Maryland and Washington, D.C. The majority of storms that… …
