Weather conditions

It is possible to overlay the current weather conditions on maps, thanks to a free service provided by GeoNames.org. When you are in the map viewer, just press the "0" button on the keyboard of the palm device - this will cause windRose to download weather data for a sector wide 2 degrees in latitude and 2 degrees in longitude centered at your current position. Pressing again "0" will toggle on and off the weather conditions and eventually reload them from the internet (in any case, they will be kept in cache for at least 15 minutes).

Two different details for weather information

An iconic representation of the weather condition will be rendered, with some additional textual information if the map zoom level is not too low (to prevent cluttering from occurring):

  • the current temperature in Celsius degrees
  • the weather observation with a METAR code:
    • DZ: drizzle
    • RA: rain
    • SN: snow
    • SG: snow grains
    • IC: ice crystals
    • PL: ice pellets
    • GR: hail
    • GS: small hail/snow pellets
    • UP: unknown precipitation
    • BR: mist
    • FG: fog
    • FU: smoke
    • VA: volcanic ash
    • SA: sand
    • HZ: haze
    • PY: spray
    • DU: widespread dust
    • SQ: squall
    • SS: sandstorm
    • DS: duststorm
    • PO: well developed dust/sand whirls
    • FC: funnel cloud
    • +FC: tornado/waterspout
  • the cloud observation with a METAR code:
    • CLR :  clear sky
    • FEW :  few clouds
    • SCT :  scattered clouds
    • BKN :  broken clouds
    • OVC :  overcast

The amount of available information depends on the contacted weather station.
