STRUCTURE OF MAG FIELD. “The size of the magnetospheric cavity is determined by the magnetic pressure of the internal field on one hand, and on the solar wind dynamic pressure on the other: The magnetospheric boundary, the magnetopause, forms at a location where the solar wind and magnetospheric plasmas and magnetic fields are in pressure balance.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

EARTH’S MAGNETISM. “The intrinsic geomagnetic field of the Earth has an intensity of about 50,000 nT in the polar regions and about 30,000 nT at the equator.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

DRIVERS OF SOLAR WEATHER. “The types of space weather phenomena at the different planets depend critically on the magnitude of the intrinsic magnetic field, on the existence and characteristics of the planetary atmosphere and ionosphere, and on the distance from the Sun determining the properties of the driving solar wind and IMF.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

“MERCURY has a small intrinsic field but no atmosphere, there the solar wind interacts directly with the surface and exosphere.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

VENUS AND MARS. “On the other hand, the inner solar system, Earth-like planets Venus and Mars possess no intrinsic magnetic field, and the magnetosphere is then mostly formed by interaction of the atmosphere and ionosphere with the solar wind flow.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

“A MAGNETOSPHERE is a cavity in the solar wind flow formed by the interaction of the solar wind and interplanetary magnetic field with the intrinsic magnetic field or ionized upper atmosphere of a planetary body. In the terrestrial case, the interaction is dominated by the strong intrinsic quasidipolar magnetic field; this is also the case of the outer giant planets Jupiter, Saturn, Uranus and Neptune.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

TIMING IS EVERYTHING. “In the life cycle of an angiosperm plant, the transition from vegetative to reproductive growth is a key developmental step that is under tight genetic control. To maximize reproductive success, the timing of this switch is coordinated with both the environment and the physiological state of the plant.” https://www.sciencedirect.com/science/article/pii/S0168952510001873 View in LinkedIn
