May 5, 2015: Tornados in Northern Germany

May 5, 2015 was a notably day with respect to meteorology. During the day showers and thundestorms were present in whole Germany. The airmass came of southwest - from the Bay of Biscay. This is typical, if thunderstorms exist in Germany. The most intense storms developed in the northeast of Germany.

In the middle of Mecklenburg-Vorpommern the town Bützow is located 20 km in the south of the city Rostock. The inhabitants will unlikely forget this day. A strong tornado developed out of a thunderstorm, that causes devastating damage. Tornados occur every year in Germany, but not so strong and not all touch occupied territory. On the basis of the damage, that the vortex left behind, this tornado must be at least a F3 one (Fujita scale).

To receive an impression of the consequences of a F3/F4 tornado I will tell you two examples from Bützow: The tornado turns a car on its roof! Other pictures show houses, that miss larger parts of the external wall! In times of smart phones there also exist some movies of residents. One movie clearly shows, that persons are in mortal danger, if they come in contact with such a tornado - even in buildings!

According to Tornadoliste of Thomas Sävert a few other tornados were present in Mecklenburg-Vorpommern this day.

General information about tornados

Tornados usually develope out of a thunderstorm cloud. Beside an unstable air mass you need changes of wind direction and/or wind speed with altitude - the expert calls this windshear. Even if all these parameters are fulfilled only a very small part of the thunderstorms form a tornado.
