    Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...

  4. Surface weather observation - Wikipedia

    en.wikipedia.org/wiki/Surface_weather_observation

    Surface weather observations are the fundamental data used for safety as well as climatological reasons to forecast weather and issue warnings worldwide. [1] They can be taken manually, by a weather observer, by computer through the use of automated weather stations , or in a hybrid scheme using weather observers to augment the otherwise ...

  5. 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 .

  6. Trend type forecast - Wikipedia

    en.wikipedia.org/wiki/Trend_Type_Forecast

    A TTF is a professionally considered forecast for weather over a two-hour period, [1] and is based on an actual weather report, such as a METAR or SPECI and appended to the end of it. [1] A TTF is similar to or sometimes in addition to a TAF, a terminal aerodrome forecast, but during the TTF's validity period is considered superior to a TAF.

  7. BUFR - Wikipedia

    Sections 0, 1 and 5 contain static metadata, mostly for message identification. Section 2 is optional; if used, it may contain arbitrary data in any form wished for by the creator of the message (this is only advisable for local use). Section 3 contains a sequence of so-called descriptors that define the form and contents of the BUFR data product.

  8. Terminal aerodrome forecast - Wikipedia

    en.wikipedia.org/wiki/Terminal_aerodrome_forecast

    In meteorology and aviation, terminal aerodrome forecast (TAF) is a format for reporting weather forecast information, [1] particularly as it relates to aviation. TAFs complement and use similar encoding to METAR reports. They are produced by a human forecaster based on the ground.

  9. Station model - Wikipedia

    en.wikipedia.org/wiki/Station_model

    This allows map users to analyze patterns in atmospheric pressure, temperature, wind speed and direction, cloud cover, precipitation, and other parameters. [1] The most common station plots depict surface weather observations although upper air plots at various mandatory levels are also frequently depicted.
