  2. Celiac plexus - Wikipedia

    en.wikipedia.org/wiki/Celiac_plexus

    The celiac plexus is often popularly referred to as the solar plexus. In the context of sparring or injury, a strike to the region of the stomach around the celiac plexus is commonly called a blow "to the solar plexus". In this case it is not the celiac plexus itself being referred to, but rather the region around it.

  3. Heliosphere - Wikipedia

    en.wikipedia.org/wiki/Heliosphere

    Because the solar wind and the ISM are both fluid, the heliosphere's shape and size are also fluid. Changes in the solar wind, however, more strongly alter the fluctuating position of the boundaries on short timescales (hours to a few years). The solar wind's pressure varies far more rapidly than the outside pressure of the ISM at any given ...

  4. Radiation pressure - Wikipedia

    en.wikipedia.org/wiki/Radiation_pressure

    Solar radiation pressure strongly affects comet tails. Solar heating causes gases to be released from the comet nucleus, which also carry away dust grains. Radiation pressure and solar wind then drive the dust and gases away from the Sun's direction. The gases form a generally straight tail, while slower moving dust particles create a broader ...

  5. Atmospheric circulation - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_circulation

    The rising air creates a low pressure zone near the equator. As the air moves poleward, it cools, becomes denser, and descends at about the 30th parallel, creating a high-pressure area. The descended air then travels toward the equator along the surface, replacing the air that rose from the equatorial zone, closing the loop of the Hadley cell ...

  6. Radiative flux - Wikipedia

    en.wikipedia.org/wiki/Radiative_flux

    In geophysics, shortwave flux is a result of specular and diffuse reflection of incident shortwave radiation by the underlying surface. [3] This shortwave radiation, as solar radiation, can have a profound impact on certain biophysical processes of vegetation, such as canopy photosynthesis and land surface energy budgets, by being absorbed into the soil and canopies. [4]

  7. Atmosphere of Earth - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Earth

    Atmospheric pressure is the total weight of the air above unit area at the point where the pressure is measured. Thus air pressure varies with location and weather . If the entire mass of the atmosphere had a uniform density equal to sea-level density (about 1.2 kg/m 3 ) from sea level upwards, it would terminate abruptly at an altitude of 8.50 ...

  8. Solar Plexus - Wikipedia

    en.wikipedia.org/wiki/Solar_Plexus_(disambiguation)

    The celiac plexus (or solar plexus) is a complex network of nerves located in the abdomen. Solar plexus or Solar Plexus may also refer to: The solar plexus chakra in Hinduism, see Manipura

  9. Inversion (meteorology) - Wikipedia

    en.wikipedia.org/wiki/Inversion_(meteorology)

    This effect is virtually confined to land regions as the ocean retains heat far longer. In the polar regions during winter, inversions are nearly always present over land. A warmer air mass moving over a cooler one can "shut off" any convection which may be present in the cooler air mass: this is known as a capping inversion. However, if this ...
