Founded in 1919, AMS has a membership of more than 14,000 professionals, ...
An eastward propagating equatorial wave that has a meridional velocity component symmetric about the equator and a zonal velocity component anti-symmetric about the MCC. For large positive (eastward) zonal wavenumbers its dispersion relation is Kelvin wave–like and for large but negative (westward) zonal wavenumbers its dispersion relation is Rossby wave– like. See also Rossby–gravity wave.
Industry:Weather
Environmental conditions favorable to promoting development of a vector (spores in the air or soil and insect populations) or disease.

One of the western boundary currents of the Pacific Ocean. It flows southward with great speed along the island of Mindanao and carries a transport of 25–35 Sv (25–35 × 10<sup>6</sup> m<sup>3</sup>s<sup>−1</sup>) from the North Equatorial Current into the North Equatorial Countercurrent. It is part of the Mindanao Eddy.
Industry:Weather
A recirculation system between the North Equatorial Current and the North Equatorial Countercurrent in the extreme west of the Pacific Ocean, east of Mindanao. The circulation is counterclockwise, about 800 km in diameter, and reaches to a depth of 250 m. Its western part forms the Mindanao Current.

The major oscillation in the Pleistocene epoch, which, according to Milankovitch, was astronomical in origin.
Industry:Weather
A radiation curve that combines the systematic effects of the precession of the equinoxes, the tilt of the earth's rotational axis, and the eccentricity of the earth's orbit. Early in the twentieth century, a Serbian mathematician and physicist, Milutin Milankovitch (1879–1958), calculated the composite solar radiation curve and used it to account for the variations of climate. He postulated that the effects of seasonal and latitudinal distribution of incoming solar radiation influenced climatic fluctuations of the order tens to hundreds of thousands of years, with each period of radiation minimum causing an ice age.
Industry:Weather
The theory, introduced by the Serbian mathematician M. Milankovitch during the first half of the twentieth century, that variations in the precession of the equinoxes and solstices, the varying tilt of the earth's rotational axis, and the varying eccentricity of the earth's orbit are responsible for the sequence of ice ages during the Pleistocene era.
Industry:Weather
Variations in climate that are due to variations in the receipt of solar radiation associated with 1) the precession of the equinoxes and solstices; 2) the varying tilt of the earth's rotational axis; and 3) the varying eccentricity of the earth's orbit.

Scattering of electromagnetic waves by homogeneous spheres of arbitrary size, named after Gustav Mie (1868–1957), whose theory of 1908 explains the process. See Mie theory; compare Rayleigh scattering.
Industry:Weather
The theory, within the framework of continuum electromagnetic theory, of scattering and absorption of a plane, harmonic wave with arbitrary frequency and state of polarization by a homogeneous sphere of arbitrary size and composition. Mie theory describes in detail atmospheric optical phenomena such as rainbows, glories, and coronas. Because Gustav Mie in 1908 was not the first to treat scattering by an arbitrary sphere, the term Lorenz-Mie theory has come into use in recent years.
