Ionosphere heating
The ionosphere is a shell of electrons and electrically charged atoms and molecules that surrounds the Earth, stretching from a height of about 50 km (30 mi) to more than 1,000 km (600 mi). It exists primarily due to ultraviolet radiation from the Sun. The lowest part of the Earth's atmosphere, the troposphere extends from the surface to about 10 km (6 mi). Above that is the stratosphere, followed by the mesosphere. In the stratosphere inco… WebTemperature/Heat, Altitude, Weather, Clouds, Layers of the Atmosphere, Ionosphere/Auroras

The quake began below the seafloor, 43 miles east of the Tohoku Region, jolting part of the seafloor upwards by 30 feet. The force of the temblor thrust Honshu—Japan’s biggest ... Web17 mrt. 2015 · The ‘wave-4’ like latent heat release pattern in the troposphere is found throughout the ionosphere–thermosphere system in various neutral and ion parameters. Dr C.H. Lin provided the Constellation Observing System for Meteorology, Ionosphere & Climate (COSMIC) figure, which is adapted with permission from Lin, C.H., et al., 2007.
Web6 mrt. 2024 · The other feature are flashes of light in the sky, similar to brief rainbows called plasma strikes, which occur when energies from the ionosphere heat up the atmosphere. And that has been observed in several earthquakes, for example in China. Much of what the Turks have now said corresponds to this. Webcations of Ionosphere-Heating technology:[6][8].
