  2. Vertical pressure variation - Wikipedia

    en.wikipedia.org/wiki/Vertical_pressure_variation

    Vertical pressure variation is the variation in pressure as a function of elevation.Depending on the fluid in question and the context being referred to, it may also vary significantly in dimensions perpendicular to elevation as well, and these variations have relevance in the context of pressure gradient force and its effects.

  3. Tidal range - Wikipedia

    en.wikipedia.org/wiki/Tidal_range

    Such weather-related effects on the tide can cause ranges in excess of predicted values and can cause localized flooding. These weather-related effects are not calculable in advance. Mean tidal range is calculated as the difference between mean high water (i.e., the average high tide level) and mean low water (the average low tide level). [2]

  4. Pressure system - Wikipedia

    en.wikipedia.org/wiki/Pressure_system

    A pressure system is a peak or lull in the sea level pressure distribution, a feature of synoptic-scale weather. The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg).

  5. Atmospheric tide - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_tide

    The largest amplitude atmospheric tides are generated by the periodic heating of the atmosphere by the Sun – the atmosphere is heated during the day and not heated at night. This regular diurnal (daily) cycle in heating generates thermal tides that have periods related to the solar day. It might initially be expected that this diurnal heating ...

  6. Sea level - Wikipedia

    en.wikipedia.org/wiki/Sea_level

    Eustatic sea level change (global as opposed to local change) is due to change in either the volume of water in the world's oceans or the volume of the oceanic basins. [14] Two major mechanisms are currently causing eustatic sea level rise. First, shrinking land ice, such as mountain glaciers and polar ice sheets, is releasing water into the ...

  7. Past sea level - Wikipedia

    en.wikipedia.org/wiki/Past_sea_level

    The snowline altitude is the altitude of the lowest elevation interval in which minimum annual snow cover exceeds 50%. This ranges from about 5,500 metres (18,045 feet ) above sea-level at the equator down to sea level at about 70° N&S latitude , depending on regional temperature amelioration effects.

  8. Pore water pressure - Wikipedia

    en.wikipedia.org/wiki/Pore_water_pressure

    Pressure develops due to: [1] Water elevation difference: water flowing from a higher elevation to a lower elevation and causing a velocity head, or with water flow, as exemplified in Bernoulli's energy equations. Hydrostatic water pressure: resulting from the weight of material above the point measured.

  9. Reference atmospheric model - Wikipedia

    en.wikipedia.org/wiki/Reference_atmospheric_model

    A reference atmospheric model describes how the ideal gas properties (namely: pressure, temperature, density, and molecular weight) of an atmosphere change, primarily as a function of altitude, and sometimes also as a function of latitude, day of year, etc.
