Strefa wzmocnionej meridional gradientów temperatury powierzchni morza i zasolenie w subtropikalnych konwergencji, w części poleward. Na półkuli południowej, subtropikalnych przodu sięgają od 40 ° S na wschodnim wybrzeżu Ameryki Południowej przez Atlantyk do Oceanu Indyjskiego i na Wielka Zatoka australijska, gdzie przesuwa go do 45 ° S, aby przejść od Tasmanii i dotrzeć na południowym krańcu nowozelandzkiej Wyspy Południowej. To w dalszym ciągu na Pacyfiku z Chatham powstanie na wschód od Nowej Zelandii w pobliżu 40 ° S i osiąga zachodniego wybrzeża Ameryki Południowej, w pobliżu 30 ° S. Na półkuli północnej przed No-opracowane subtropikalnych istnieje na Pacyfiku pomiędzy 25 ° N, 135 ° E i 30 ° N, 140 ° W.

1. The number of oscillations per second of the electric and magnetic fields in the radio portion of the electromagnetic spectrum, generally that portion between 10<sup>4</sup> and 10<sup>12</sup> Hz; specifically, the frequency of a given radio carrier wave. 2. In radio or radar, pertaining to a signal at the transmitted or received frequency, as opposed to a signal translated to a different frequency (IF signal) or detected (video signal).

A nondimensional number arising in problems of a rotating viscous fluid. It may appear either as Ω''h''<sup>2</sup>/ν, in which case it equals one-half the square root of the Taylor number, or as Ω''r''<sup>2</sup>/ν, where ''r'' is a suitable radius, ''h'' a representative depth, Ω the absolute angular speed, and ν the kinematic viscosity.

1. In meteorology, an elongated area of relatively high atmospheric pressure, almost always associated with and most clearly identified as an area of maximum anticyclonic curvature of wind flow. The locus of this maximum curvature is called the ridge line. Sometimes, particularly in discussions of atmospheric waves embedded in the westerlies, a ridge line is considered to be a line drawn through all points at which the anticyclonically curved isobars or contour lines are tangent to a latitude circle. The most common use of this term is to distinguish it from the closed circulation of a high (or anticyclone); but a ridge may include a high (and an upper-air ridge may be associated with a surface high) and a high may have one or more distinct ridges radiating from its center. The opposite of a ridge is a trough. 2. Also used as reference to other meteorological quantities such as equivalent potential temperature, temperature, and mixing ratio. That is, an elongated area of relatively high values of any particular field emanating from a maximum. 3. In oceanography, a linear accumulation of broken ice blocks projecting upward, formed by ice deformation, often at the edge of a floe. A ridge is distinguished from a hummock by being much longer than it is wide. The term ridge is often used to describe an entire ridged ice feature, in which case the portion above the water line is termed the sail and the portion below the water line is termed the keel.

Industry:Weather
The component of an instrument that converts an input signal into a quantity that is measured by another part of the instrument.
Industry:Weather
General name for the class of actinometers that measure the combined intensity of incoming direct solar radiation and diffuse sky radiation. The pyranometer consists of a recorder and a radiation sensing element that is mounted so that it views the entire sky (radiation from the solid angle 2π on a plane surface). See pyrheliometer, Robitzsch actinograph, albedometer.
Industry:Weather
An ice crystal exhibiting an elaborately branched (dendritic) structure of hexagonal symmetry, with its much larger dimension lying perpendicular to the principal (c axis) of the crystal. Such crystals usually form by vapor deposition at atmospheric temperatures between about −14° and −18°C. In sufficient concentration they readily aggregate to snowflakes by interlocking of their branches. See dendrite.
