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, ...
A cooperative project between the United States and France to develop an advanced satellite system dedicated to observing the earth's oceans. The TOPEX/Poseidon satellite, launched in September 1992, uses sophisticated altimeters to make sea level measurements in combination with a microwave radiometer to correct the altimeter measurements for changes in total water vapor content of the atmosphere, resulting in an absolute accuracy of about 4 cm.
Industry:Weather
The highest frequency that can be determined in a Fourier analysis of a discrete sampling of data. If a time series is sampled at interval Δ''t'', this frequency is 1/2Δ''t'' cps.
Industry:Weather
A wind scale adapted by the U. S. Forest Service for use in the forested areas of the northern Rocky Mountains (sometimes abbreviated NRM). It is an adaptation of the Beaufort wind scale. The difference between these two scales lies in the specification of the visual effects of wind; the force numbers and the corresponding wind speeds are the same in both.

The nanotesler (nT); a measure of geomagnetic field strength. There are 10<sup>9</sup> nanoteslers in a tesler, which is the unit of measure of magnetic field strength in the SI system of units. An nT is equal to a gamma. There are 10<sup>5</sup> gammas in an oersted, which is the unit of measure of magnetic field strength in the cgs system.
Industry:Weather
Phenomenon found in the upper atmosphere during winter and early spring in which the total column amount of active nitrogen is reduced due to the removal of nitric acid. The mechanism is closely related to denitrification in polar regions.
Industry:Weather
The Greek name for the south wind, sultry and rainy. On the Tower of the Winds in Athens it is represented by a lightly clad young man carrying an inverted jar from which water is falling.

This phenomenon owes its name to an event in 1596 when explorers (in search of the northeast passage) wintering on the island of Nova Zemlya saw a distorted image of the sun two weeks before astronomical calculation would have had it rise. Since that time, the term has been used generically for any such observation of an image of the sun when the actual sun was substantially below the horizon. In the original case, the angular difference between the image and the object was 5°. This is explained by the ducting of the sunlight between the surface and a lifted inversion.
Industry:Weather
One of the water masses, with a temperature of −0. 95°C, that contributes to the formation of Arctic Bottom Water.
Industry:Weather
A warm current flowing northeastward along the Norwegian coast. It is the continuation of the North Atlantic Current and discharges about 10 Sv (10 × 10<sup>6</sup> m<sup>3</sup> s<sup>−1</sup>) into the Arctic Ocean. Because its waters are of subtropical origin it has a significant impact on the climate of northern Europe; ports in northern Norway located at 70°N are ice-free throughout the year.
Industry:Weather
The steep water-temperature gradient between the Gulf Stream and 1) the Slope Water inshore of the Gulf Stream or 2) the Labrador Current north of the Gulf Stream.
