    1500 km long: Impressive squall line storms Europe

1500 km long
Impressive squall line storms Europe

An unseasonably strong squall line stretched across several European countries as it marched eastwards on Monday.

On Monday 13th March, a squall line, which originated in France after temperatures soared over 26C, spanned a length of 1500 km into Germany, Switzerland and Italy through the evening.

The squall line, consisting of a cluster of very active, potent thunderstorms, produced over 180,000 lightning strikes across these countries.

On Monday 13th March, impressive thunderstorm cells developed, such as this one near Würzburg, Germany.

Strong to severe thunderstorms developed with reports of gusts up to 65 mph producing damage, alongside large hail reported up to 3 cm in diameter.

Strong supercells were also reported in southern Germany and eastern France, with a visible hook echo and strong rotation on the radar; key signs of tornado formation.

In coincidence, an unconfirmed tornado was also reported on the very same day in Great Hucklow, in the Derbyshire Peak District.

The localised, but severe damage is classic to a tornado. Several trees were torn down, greenhouses were smashed and sheds were even lifted into neighbours' gardens.

The image shows an intense tropical cyclone over the western Pacific, east of Taiwan and the Philippines. The centre of the system is depicted as a light purple and white vortex with a clearly visible eye, surrounded by a ring of red and orange areas indicating the strongest wind speeds. A white arrow marks the typhoon’s predicted track towards the north-west, in the direction of Taiwan. To the west of the storm lie the Philippines, with the cities of Manila and Cebu; to the north of these lies Taiwan, with Taipei. Further west, the Chinese coast, including Hong Kong, and parts of Vietnam can be seen. The coloured wind map shows predominantly green areas outside the storm’s core, indicating significantly weaker winds. White streamlines illustrate the typhoon’s anti-clockwise circulation in the Northern Hemisphere. The highest wind speeds are concentrated around the eye of the cyclone.
