  2. Ionosphere - Wikipedia

    en.wikipedia.org/wiki/Ionosphere

    The worldwide solar-driven wind results in the so-called Sq (solar quiet) current system in the E region of the Earth's ionosphere (ionospheric dynamo region) (100–130 km (60–80 mi) altitude). [citation needed] Resulting from this current is an electrostatic field directed west–east (dawn–dusk) in the equatorial day side of the ionosphere.

    Layers of the ionosphere.The Kennelly–Heaviside layer is the E region. The Heaviside layer, [1] [2] sometimes called the Kennelly–Heaviside layer, [3] [4] named after Arthur E. Kennelly and Oliver Heaviside, is a layer of ionised gas occurring roughly between 90km and 150 km (56 and 93 mi) above the ground — one of several layers in the Earth's ionosphere.

    This includes the effects of the solar wind, especially on the Earth's magnetosphere, ionosphere, thermosphere, and exosphere. [1] Though physically distinct, space weather is analogous to the terrestrial weather of Earth's atmosphere (troposphere and stratosphere). The term "space weather" was first used in the 1950s and popularized in the ...

    In ancient Greek medicine, each of the four humours became associated with an element. Blood was the humor identified with air, since both were hot and wet. Other things associated with air and blood in ancient and medieval medicine included the season of spring, since it increased the qualities of heat and moisture; the sanguine temperament (of a person dominated by the blood humour ...
