What remains of the winter 2010/2011 in Austria?

Hello and good morning to the last Sunday of the meteorological winter 2010/2011.

stuff to climate budgets and looking back on the drawing to the end of winter, one might easily have been the last few days from the media. I may refer you to this point as to our * own * Looking back to read, among other things in the PRESS.

I want to look back on the blog make it a bit different and more large-scale characteristics of the light that led to that have what we have experienced the weather in the past 3 months, and, above all in the last 8 weeks experienced.

remember we all vividly that winter, when winter really mean by wintry weather, almost all his powder has already missed the first 3 weeks of December. This resulted in two weather conditions with high temporal stability, exemplified by those from 1.12 shown:

deep potential in the south and southwest of the Alps, high in the north led to recurrent sliding of hot-rolled - to cold air, the result was in regular amounts of snow, in particular in the southeast and east.

In the second third of December then another snowy variation ...

The deep potential had since shifted more to the east, high in the West. Snowfalls along the northern Alps and the east were the result, the snow cover reaches the plains with some more than 40cm its maximum ..

... in the last third of it went with the winter but essentially over:

The deep potential now lies in the west, from south eroded the mild air, the snow cover in large parts across the country within 24 hours. The following trough passage generous with snow falls, so the year but then again cold, but otherwise not particularly winter fades.

A bad omen for the constellations in the 4.5 weeks of January that followed .. the pressure over the Mediterranean rose sharply, and fell just as much of Scandinavia ... the West-heavy phase of the winter began ... example the situation at 1.6

.. interrupted only by the most exciting for me the weather of the winter on 13 or 14.1 ...

.... where a marked warm front fell from the northwest to the central parts of the northern Alps partly more than 100 inches of rain and have led to a part of the authorities played down the flood situation along the Danube and its northern tributaries .....

.... We stayed in the rest of January, mostly on the anticyclonic side of the frontal zone without much weather activity. This west facing position without the otherwise typical West storms is another, less glorious particularity.

Only once could we then speak later in the month of February, local West tower, as in the Vienna final amount of flow, the ideal wind direction and Föhneffekte worked together so that gusts were reached to 112 km / h, on hills in the area to 124 km / h ....

As a result, the temperature difference between Southwest and Northeast generally larger again and on the surface separated a front the country into a mild west and southwest and a cold north and east, a pattern that after a short interruption in the last months decade again stopped ...

What weather conditions that we are one of a typical winter flow, we thought it's how often?

Mediterranean cyclones: overrepresented in December, missing in January, raking profits in February.

West locations: Dry modification in January and early February dominant, storms missing almost.


storage locations in the northern Alps: With one exception in December and at the 1.14 missing.


anticyclones: overrepresented in January and early February.


is the picture of a winter, from which one can not make a simple picture, there is no common thread running through. Rather, one has to a marked break in the NH-Zirk. beginning of January and try to face the two unequal parts, the December on the one side, January and February on the other side, of a recent break in late February.

What does the March?

I have the feeling that the March winter is coming .... maybe more tomorrow;)
