I'm looking for Gliding Weather Services around the world similar to
MeteoSwiss (for Gliders) or Alpenflugwetter.
Do you know other "gliding weather websites"?

http://expert.weatheronline.co.uk
Has many interesting charts
- all cover the UK
- some cover Europe as well
- some are particularly useful for gliders,
e.g. wind at 900hPa/3000ft AMSL
plus an explanation of why the chart is useful and
how to interpret it
