  2. Station model - Wikipedia

    en.wikipedia.org/wiki/Station_model

    The present weather symbol depicts the current weather which normally is obstructing the visibility at the time of observation. The visibility itself is shown as a number, in statute miles in the United States and meters elsewhere, describing how far the observer can see at that time. This number is located to the left of the present weather ...

  3. SYNOP - Wikipedia

    en.wikipedia.org/wiki/SYNOP

    SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by staffed and automated weather stations. SYNOP reports are typically sent every six hours by Deutscher Wetterdienst on shortwave and low frequency using RTTY .

  4. Meteogram - Wikipedia

    en.wikipedia.org/wiki/Meteogram

    An example meteogram showing plots of temperature, pressure, precipitation, cloud cover, wind speed and wind direction. A meteogram, also known as a meteorogram, [1] is a graphical presentation of one or more meteorological variables with respect to time, whether observed or forecast, for a particular location. [2]

  5. Visibility - Wikipedia

    en.wikipedia.org/wiki/Visibility

    The visibility from an elevated observation point down to the surface of the sea can be calculated using the Pythagorean theorem, since the line of sight and the radius of the Earth form the two legs of a right triangle. The height of the elevated point plus the Earth radius form its hypotenuse. If both the eyes and the object are raised above ...

  6. Weather balloon - Wikipedia

    en.wikipedia.org/wiki/Weather_balloon

    Weather balloons are launched around the world for observations used to diagnose current conditions as well as by human forecasters and computer models for weather forecasting. Between 900 and 1,300 locations around the globe do routine releases, two or four times daily, usually at 0000 UTC and 1200 UTC.

  7. Weather satellite - Wikipedia

    en.wikipedia.org/wiki/Weather_satellite

    A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites are mainly of two types: polar orbiting (covering the entire Earth asynchronously) or geostationary (hovering over the same spot on the equator ).

  8. Weather map - Wikipedia

    en.wikipedia.org/wiki/Weather_map

    A surface weather analysis is a type of weather map that depicts positions for high and low-pressure areas, as well as various types of synoptic scale systems such as frontal zones. Isotherms can be drawn on these maps, which are lines of equal temperature. Isotherms are drawn normally as solid lines at a preferred temperature interval. [2]

  9. Weather station - Wikipedia

    en.wikipedia.org/wiki/Weather_station

    Weather ship observations proved to be helpful in wind and wave studies, as they did not avoid weather systems like merchant ships tended to and were considered a valuable resource. [5] The last weather ship was MS Polarfront, known as weather station M ("jilindras") at 66°N, 02°E, run by the Norwegian Meteorological Institute.
