School In normal situation, the air cools as it moves away from the Earth's surface. Thus, the air near the surface, warmer climbs, making room for the cooler air down, favoring the dispersion of pollutants (upper figure). During the phenomenon of thermal inversion, a layer of heated air builds up over a layer of cool air, preventing the process, hindering movimeto ascending air, causing pollutants to accumulate and remain near the surface of the earth. Adapted from http://www.cetesb.sp.gov.br/ The phenomenon of thermal inversion remains active while under the effect of high pressure and low wind speeds. Other aspects that favor the thermal inversion are: the time of year and time of day, occurring more frequently in winter and early morning. The metropolitan environments that are also favors the heat exchange, because of the large floor area, absorb heat radiating during the day and at night quickly. Among the forms of heat transfer,is the radiation process by which the sun emits heat. A part of the radiation is absorbed or reflected by the elements of the atmosphere itself, while another part is reflected or absorbed into the surface. The solar radiation absorbed by the Earth's surface is largely responsible for its heating. To be warmer than the air, the surface emits heat. With these considerations, we say that the earth and the atmosphere exchange heat by radiation and conduction. These processes of heat transfer - conduction, radiation and convection - are not present only in the climatic behavior of our planet, but also in living beings! Thermodynamics

Škola U normalnoj situaciji, zrak hladi dok se kreće dalje od Zemljine površine. Dakle, zrak pri površini, toplije penje, što boravak za hladnijeg zraka prema dolje, favoriziranje disperzije onečišćujućih tvari (gornja slika). Tijekom fenomena toplinske inverzije, sloj zagrijanog zraka nakuplja na sloj hladnog zraka, spriječava proces, koči movimeto uzlaznu zrak, što uzrokuje zagađivači akumulirati i ostati blizu površine zemlje. Prilagođeno iz http://www.cetesb.sp.gov.br/ Fenomen toplinske inverzije ostaje aktivan dok je pod utjecajem visokog tlaka i niske brzine vjetra. Ostali aspekti koji pogoduju temperaturna inverzija su: doba godine i vrijeme dana, javljaju češće zimi iu rano jutro. The Metropolitan okruženja koji su također pogoduje razmjenu topline, zbog velike površine, upijaju toplinu zrači danju i noću brzo. Među oblicima prijenosa topline,zračenje, proces kojim sunce emitira toplinu. Dio zračenja se apsorbira ili reflektira od elemenata u atmosferi sama, a drugi dio se reflektira ili apsorbira u površinu. Sunčeva zračenja apsorbira na Zemljinoj površini je u velikoj mjeri odgovoran za njezino grijanje. Da bi biti toplije od zraka, površina emitira toplinu. S tih razmatranja, možemo reći da je na zemlji i toplina atmosfere razmjene zračenjem i vođenje. Ovi procesi prijenosa topline - provođenje, zračenja i konvekcije - nisu prisutni samo u klimatskom ponašanje našeg planeta, ali i živih bića! Termodinamika
