  1. Weather in switzerland has a lot o local differences...

    On the southern side of the alps the climate is a little bit warmer than in the north, but the really important thing to consider is that the alps form a barrier that separates two completely different aspect of a weather situation.

    For example there may be a high-pressure area in Italy and low pressure in central Europe, so there will be southern wind crossing the alps. While ascending in southern Switzerland the air will get cooler, vapour will condensate and there will be rain. North of the alps the falling wind will be dry and warm (föhn). Often föhn wind brings a little sunshine in the Rhine valley between Chur and Lake Constance and in the Reuss valley from Altdorf to Lucerne while there are clouds over northern Switzerland. The same effect can of course also be observed in opposite direction.

    When consulting a weather forecast for Switzerland it is therefore very important to focus exactly on the correct region. In a few mile, here in Lugano with the lake during the night in winter temperature is between 0 and -5 degree, 15 km south ( without lake but always at low level ) between -5 and -10 degree.

    In the Southern region (Ticino area), a much higher average precipitation amount of about 2000 mm/year (78 inches) is observed. In 2010 for example 2460 mm rain ( 97 inches ). Rain and snow event are rather short but often very intense, for example 100 mm in a day in southern switzerland it's not exceptional. Everywhere, except for the Valais region, the amount of rainfall is approximately twice as large in the summer as in the wintertime.

  2. For this region of Spain surely a very important event. perhaps every 100 years. Ok here in southern switzerland obvously not frequent 1 meter snow at low level but every winter at least 5 snowfalls of 15 - 25 cm, in the last november week we had 4 snowfall in 10 days and the total amount at low level was 47 cm. This photo I took it on 28 November in Lugano, total snowfall 21 cm in a day.

  3. Those photos are from here in southern switzerland ( near Lugano ) in january 2006, one of the most important snowfall in the last 15 years, in 36 hours at low level ( that mean 200 - 300 Meter ) from 90 to 105 cm ( about 40 inches ). Otherwise average amount snow in the winter is about 75 cm at low level and average precipitation every year 1800 - 2000 mm.
