He has struck again. Although he is now broken only briefly ... The already rudimentary snow was in the last 4 days by continued positive temperatures (at night) further decimated.
balance in the last days:
Sunday: Violent hair dryer in the mountains: PAK with 130 km / h, Uni at 90 km / h and at the airport after all, about 70 km / h - blowing snow - road closure due to accident between Sistrans and Innsbruck
Monday morning still Hair Dryer (120 km / h at the PAH), is weakening. Still snow drifts - Stubaital railway line for 4 h blocked
Tuesday: High hair dryer makes itself felt again (137 km / h) - he does not break through the valley, but on Tuesday night, the temperatures remain due vorföhnigem West (40km / h) is positive.
Wednesday: no snow drifts more because there is no more snow! PAK: 133, University of 50 km / h

The Uni-Innsbruck informed by the way today with fire in first place as a hot spot in Austria with 13.1 degrees. This was made possible the strong and becoming warmer Föhnströmung in height (see SAB).

This is one from the December record of Innsbruck (19.0 on 12/07/1953) beside still a few degrees - but the consoles do not get over the melting fact that the Christmas thaw has begun ...
Speaking of Christmas ...
2009 (red) was in contrast to the end of November 2010 already far too warm. Then followed a virtually identical curve: at 6.12. Both curves intersect the means - to 11-12. December is up to 5 degrees warmer followed the same running cold period (2009 to 20, 2010 to 17th), but it changes: the brown 2010s curve goes up 3 days earlier and exceeds 21 the means. The 24th Although this year will be well above the average, but the crass Föhnabend warm (14 degrees by 20 clock) from last year, we are spared (see blog entry from last year ) ...
interesting detail: the Christmas thaw is also reflected in the 30-year temperature curve apparent: about 17 around it by almost 1 degree (which is now estimated, however!) warmer. Climate Change the Odds: old patterns (after all, a statistic from 1961-1990) as the turning of the flow from north to south (as the primary driver of rising temperatures around the 24th round) We will also receive 2010th
Short balance Precipitation:
2010 was considerably drier than the long-term average - about 100 mm missing is balance in Innsbruck.
was compared to the Sahel Inntal Bregenz a water world. That it is exposed and therefore there is wet, no surprise. Heuer however, fell far short 500 mm (!!!) more than the average, an increase of 25%. Extreme, it was only in the north-east of Austria (not shown): Langenlois example, was at 160% of average annual rainfall (710 instead of 445 mm) the wettest.
... seen even after warm (3 - 4 degrees) Christmas in the Innsbruck area from - but makes for a warm front precipitation, first rain, then snow.
The hope: the rain makes on Christmas Eve for wetting the Föhnschicht. This is even after the collapse on Thursday evening, probably on Friday found. From South Italy engages deeply about and from the north flows colder air. The faster the more snow.
The fear: in the first batch is not too much of - the air is too dry and the precipitation evaporates before it reaches the ground. Since it comes back on it at once if the cold air is already in the Inn valley (down by 8 degrees in the height).
problem: on 24 at 18 UTC, it is too warm for snow (the last runs of the show).
But on 25 at 06 UTC, it's been so cold that the snow line potential is already at 500 m!
We will see ...
