1. Reduction in intensity. 2. The decrease in the magnitude of current, voltage, or power of a signal in transmission between points. Attenuation may be expressed in decibels, and can be caused by interferences such as rain, clouds, or radio frequency signals.
Industry:Earth science
A sedimentary rock composed almost entirely of calcium carbonate (CaCO3), mainly as calcite. Limestones consist of fragments of shell or of calcite deposits precipitated by certain algae.
Industry:Earth science
A seasonal wind caused primarily by a greater annual variation of temperature over large land area than over neighboring ocean surfaces causing an excess of pressure over the continents in the winter and a deficit in the summer; monsoons are strongest in Asia, but also occur on the coasts of tropical regions.
Industry:Earth science
Vento stagionale provocato principalmente da una maggiore variazione annuale nella temperatura sopra una grande area di terraferma rispetto alle superfici oceaniche circostanti aumentando così la pressione sopra i continenti in inverno e una diminuzione in estate; i monsoni sono più forti in Asia ma si verificano anche lungo le coste delle regioni tropicali.
Industry:Earth science
Una roccia sedimentaria composta quasi interamente da carbonato di calcio (CaCO3), principalmente come calcite. Calcari sono costituiti da frammenti di conchiglia o di calcite depositi precipitati da alcune alghe.
Industry:Earth science
A vertical density gradient (as determined by the vertical temperature and salinity gradients and equation of state) in some layer of a body of water, which is appreciably greater than the gradients above and below it; also a layer in which such a gradient occurs. The principal pycnoclines in the ocean are either seasonal, due to heating of the surface water in summer or fresh water inputs, or permanent.
Industry:Earth science
An atmospheric pressure system consisting of an area of high pressure and outward circular surface wind flow. In the Northern Hemisphere winds from an anticyclone blow clockwise, while Southern Hemisphere systems blow counterclockwise and undefined at the Equator.
Industry:Earth science
A standing wave phenomenon associated with the reflection of an ocean-wave train from a vertical surface, such as a breakwater or pier.
Industry:Earth science
Un sistema di pressione atmosferica costituito da un'area di alta pressione e flusso di vento di superficie circolare verso l'esterno. Nell'emisfero nordico venti da un anticiclone soffiano in senso orario, mentre l'emisfero sud sistemi soffiano in senso antiorario e indefinito all'equatore.
Industry:Earth science
A cross-sectional plot of beach survey data, which can be used to illustrate seasonal and long-terms changes in beach volume.
