Surface weather observations can include the following elements: The Station Identifier, or Location identifier, consists of four characters for METAR observations, [13] with the first representing the region of the world the station lies within. For example, the first letter for areas in and around the Pacific Ocean is P, and for Europe is E.
The standard measuring conditions for temperature are in the air, 1.25 metres (4.1 ft) to 2.00 metres (6.6 ft) above the ground, [5] and shielded from direct sunlight intensity (hence the term x degrees "in the shade"). [6]
Initial efforts to create surface weather analyses began in the mid-19th century by using surface weather observations to analyze isobars, isotherms, and display temperature and cloud cover. By the mid-20th century, much more information was being placed upon the station models plotted on weather maps and surface fronts, per the Norwegian ...
The following is an example METAR from Burgas Airport in Burgas, Bulgaria. It was taken on 4 February 2005 at 16:00 Coordinated Universal Time (UTC). METAR LBBG 041600Z 12012MPS 090V150 1400 R04/P1500N R22/P1500U +SN BKN022 OVC050 M04/M07 Q1020 NOSIG 8849//91= METAR indicates that the following is a standard hourly observation.
In this example the METAR indicates it is from EGXE (RAF Leeming) at 1150 UTC on Day 6. The observation follows (see METAR for explanation), with the Trend added to the end of the observation. The Trend reads TEMPO 6000 SHRA SCT020 WHT i.e. Temporary deterioration to 6 km visibility in a moderate rain shower with scattered at 2000 ft, colour ...
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.
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 .
A surface weather analysis for the United States on October 21, 2006. By that time, Tropical Storm Paul was active (Paul later became a hurricane). Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.
