The American Meteorological Society promotes the development and dissemination of information and education on the atmospheric and related oceanic and hydrologic sciences and the advancement of their professional applications. Founded in 1919, AMS has a membership of more than 14,000 professionals, ...
The part of meteorology that deals mainly with the study of oceanic areas, including island and coastal regions.
In particular it serves the practical needs of surface and air navigation over the oceans. Since there is a close interaction between ocean and atmosphere, and oceanic influences upon weather and climate can be traced far inland over the continents, modern meteorology uses this name mainly for making regional or administrative distinctions.

The angular distance of any celestial object from a given observer's zenith, measured along the great circle of the celestial sphere from the zenith to the object; the complement of the elevation angle.
Industry:Weather
The layer of ground, between the active layer and permafrost, where the temperature remains nearly constant at 0°C.
Industry:Weather
Ordinary lightning of a cloud-to-ground discharge that appears to have a single, but very irregular, lightning channel.

A balloon that is not sealed.
The base of the balloon may be open or it may have a duct high on the balloon that is attached at or near the base of the balloon. The opening is used to vent excess gas when the balloon reaches ceiling altitude. The large plastic balloons used to carry scientific payloads to altitudes above 40 km are zero-pressure balloons.
Industry:Weather
An approximation to turbulent flow that utilizes empirical diagnostic relationships for the mean variables such as wind speed and temperature.
Because these are diagnostic equations rather than prognostic, there are no forecast equations for turbulence statistics of any statistical order including the first-order mean values. An example is the logarithmic wind profile in the surface layer, a similarity theory that gives the wind speed as a function of height without using the equations of motion. See closure assumptions, first-order closure, higher-order closure, nonlocal closure.

In the Tropics or subtropics, rainy seasons that recur annually or semiannually at about the time that the sun is most nearly overhead (at zenith).
Within a few degrees of the equator, two such periods of heavy rains may occur annually, the equinoctial rains. Farther from the equator, these blend into a single annual summer rainy season.
