Abstract
Termosfera je gornji dio atmosfere koji karakteriziraju iznimno visoke temperature. Proteže se od 80-90 km nadmorske visine do između 500 i 1000 km iznad površine Zemlje, ine i ju najširim dijelom atmosfere. Osim niskog tlaka, u termosferi su uo ene nagle varijacije vrijednosti temperature, koje rastu s nadmorskom visinom. Glavne komponente termosfere su atomski kisik, atomski dušik, helij i vodik. Kemijske reakcije u termosferi, esto potaknute sun evim zra enjem, te proces molekularne difuzije, koji razdvaja plinove prema masi, igraju važnu ulogu u ovom atmosferskom sloju. Cirkulacija u termosferi je uzrokovana atmosferskim plimama i valovima, dok se na visini od 100 do 1000 km iznad Zemljine površine pojavljuje polarna svjetlost. Ovaj fenomen nastaje zbog interakcije Sun evog vjetra s atmosferom, a boja polarnih svjetlosti ovisi o sudarima kisikovih i dušikovih atoma s elektronima.
Abstract (english)
The thermosphere is the upper part of the atmosphere characterized by extremely high temperatures. It extends from 80-90 km above sea level to between 500 and 1000 km above the Earth's surface, making it the widest part of the atmosphere. Besides the low pressure, the thermosphere experiences rapid temperature variations, which increase with altitude. Its main components are atomic oxygen, atomic nitrogen, helium and hydrogen. Chemical reactions in the thermosphere, often triggered by solar radiation, and the process of molecular diffusion, which separates gases by mass, play a significant role in this atmospheric layer. Circulation in the thermosphere is caused by atmospheric tides and waves, while polar lights appear at altitudes ranging from 100 to 1000 km above the Earth's surface. This phenomenon arises from the interaction of the solar wind with the atmosphere, and the color of the polar lights depends on collisions between oxygen and nitrogen atoms with electrons.
