Il lato di un ciclone tropicale a sinistra della direzione di movimento della tempesta nell'emisfero settentrionale (a destra nell'emisfero australe), dove i venti sono più deboli perché Sottrai velocità di traslazione e rotazione di ciclone. Confronta semicerchio pericoloso.

Un vento spira con il bel tempo che soffia, soprattutto in estate, nel mare Adriatico; è più frequente sul puntello occidentale ed è equivalente alla etesians del Mediterraneo orientale. Si trova anche sulle coste della Corsica e Sardegna. Confronta mistral.

La parte della meteorologia che si occupa principalmente dello studio delle aree oceaniche, comprese le regioni insulari e costiere.
In particolare serve le esigenze pratiche di navigazione di superficie e l'aria sopra gli oceani. Poiché vi è una stretta interazione tra oceano e atmosfera, e influenze oceaniche su meteo e clima possono essere rintracciate lontano verso l'interno sopra i continenti, meteorologia moderna utilizza questo nome principalmente per fare distinzioni regionali o amministrative.

A positively charged subatomic particle with a rest mass of 1. 67262 x 10<sup>−27</sup> kg, slightly less than that of the neutron and about 1836 times that of the electron. Atomic nuclei are composed of protons and neutrons bound together by nuclear forces. The common term for neutron or proton is nucleon.

La reducción, con distancia de la fuente de la intensidad de una acústica o una señal electromagnética que se propaga a través de la atmósfera causada por la interacción de la señal con los componentes gaseosos de la atmósfera, aerosoles o hidrometeoro. En general, dispersión y absorción representan atenuación. Para el sonido, la absorción es generalmente más importante que la dispersión; depende de la temperatura y la humedad y generalmente aumenta con el aumento de frecuencia acústica. Los principales constituyentes atmosféricos que absorben la energía del radar son hidrometeoro líquido, oxígeno y vapor de agua. Absorción es a menudo descuidadas en longitudes de onda de 10 cm y largo, pero se vuelve cada vez más importante en longitudes de onda más cortas. La contribución de la dispersión a atenuación de radar también aumenta con la disminución de longitud de onda. Para lidar, dispersión de moléculas, aerosoles e hidrometeoro domina la atenuación, aunque la absorción gaseosa es significativa en determinadas bandas espectrales y es explotada por absorción diferencial lidar (DIAL) para medir las concentraciones moleculares.

1. A gaseous envelope gravitationally bound to a celestial body (e. G. , a planet, its satellite, or a star). Different atmospheres have very different properties. For instance, the atmosphere of Venus is very thick and cloudy, and is responsible for producing the very high surface temperatures on that planet by virtue of its greenhouse effect. On the other hand, the Martian atmosphere is very sparse. Earth's atmosphere is intermediate between these two extremes. It is distinguished from all other known atmospheres by its very active hydrologic cycle. One need merely examine pictures of Earth from space to appreciate the intricate cloud structures. Water in Earth's atmosphere plays a very important energetic role. Because of its chemical composition, most incoming sunlight passes through Earth's atmosphere and is absorbed at the ground. This heat is transported to the atmosphere through sensible heat and moisture fluxes. Upon condensation, this heat is then released into the atmosphere. The thermodynamics of water vapor is the crucial factor to the existence of severe storms in Earth's atmosphere. Since more solar radiation is absorbed in the Tropics than at high latitudes, the atmosphere (and the ocean) transports heat poleward. These motions are heavily altered by the effects of planetary rotation to determine the atmospheric general circulation. Fluid dynamical instabilities play a large role in this circulation and are crucial in determining the fluctuations in this circulation that we call “weather. ”The atmosphere may be conceptually divided into several layers, according to its thermal and ionization structure. The region where the temperature decreases because of the upward heat flux is called the troposphere. Above it, there is a layer in which temperature increases upward because of ozone absorption of solar radiation, the stratosphere. Above this, the temperature decreases in the mesosphere, and above this, in the thermosphere, the extremely energetic radiation causes temperature to increase with height out to the outer reaches of Earth's atmosphere, the exosphere. Within the mesosphere and thermosphere, solar radiation is sufficiently energetic to ionize gases. This produces the ionosphere. 2. As a unit of pressure, see standard atmosphere. 3. See standard atmosphere, model atmosphere.
