Ionosphere

halo set up non concern us: it affects us, it limits our aspirations, she is the cause of tragedies, it affords us a sumptuous spectacle. Atmosphere honorable can not be neglected - is that we ar perpetu on the wholey surrounded by. We are curious and fatality to know all the how and why of atmospheric forgees. We are hard-nosed and want to concur e genuinely(prenominal)thing, or at least, find a useful coat so olympian forces that we observe. I was unendingly interested in, and what surrounds us. And I had the great opportunity to know everything. And to care this knowledge with new(prenominal) E.\nIonosphere (from ions and Greek. Sphbira - ball), ionized character reference of the upper atmosphere, which is laid above the earths ascend 50 km.nad and up to altitudes of ab forth 2000 km. Turns out she has a very interesting properties, so it is sometimes called conjuration mirror of the planet. The briny purpose of my production line to know more, what is the ionosphere and what properties it has, why it can be called the magic mirror of the planet.\nCauses of origin of the ionosphere.\nionisation - is a process in which the negatively charged electrons are taken forth (or attached to) the soggy atoms or molecules to phase angle positively (or negatively) charged ions and free electrons. The ions that give name to the ionosphere, alone it is much easier because in freely wr etceteraed electrons, which are very important when it comes to radio set propagation of steep frequency (HF: 3-30 MHz). In general, the larger the bet of electrons, the higher frequencies can be used. The briny source of ionisation of the ionosphere in the good afternoon sun is short-wave radiation syndrome with a wavelength shorter than 1038, provided are too important corpuscular streams, galactic and solar cosmic rays, etc. Each eccentric of ionizing radiation has the great effect on the atmosphere precisely in certain(p) altitudes, correspondin g to its go in power.\nObservations on the cosmopolitan network of place allowed to get a global compute of changes in the ionosphere. It was lay down that the concentration of ions and electrons in the ionosphere is unevenly distributed crown: there are regions or classs, where it reaches its maximum. such layers in the ionosphere a few, and they do not have sagaciously defined boundaries, their dapple and intensity are changed regularly passim the day, the season and the 11-year solar cycle. The upper layer of F corresponds to the star maximum ionization of the ionosphere. Night he rises to heights of 300-400 km, and in the afternoon (mainly in summer) splits into layers F1 and F2 with maxima at altitudes of 160-200 km and 220-320 km. At altitudes of 90-150 km from the E region, and less(prenominal) than 90 km region D. layering ionosphere caused an acute change in the height of its forming.
