Weather symbol legends

  • Red (upper-left): temperature (°C)
  • Green (lower-left): dewpoint (°C)
  • Blue (upper-right): abbreviated mean sea-level pressure in hPa (=mb). To get the pressure value, just put a 10 or a 9 in front of the displayed value and divide by 10: only one of these choices will give a realistic value.
  • Magenta (center-left): weather symbol (vedi successiva tabella con i SIMBOLI DELLE CARTE METEO)
  • Blue (center): cloud cover in octa
  • Blue (barb): wind speed in knots and wind direction
  • Orange: pressure tendency in the last 3 hours in tenth of hPa
  • Purple (left-upper-left): Wind gust in knots
  • Upper-center and lower-center (few stations): cloud type symbols
  • Black lines: pressure (hPa=mb) lines each 4 hPa analyzed with Barnes algorithm from surface observations and first guess model data (digital filter)
  • Red dashed-lines: geopotential height at 500 hPa each 6 dam analyzed with Barnes algorithm from upper-air observations and first guess model data
