Violent bombing cyclone Ciarán triggers high alert in Western Europe

A powerful bomb cyclone, one of the most violent in Western Europe in the last 30 years, begins to hit countries such as France and England. The storm is so severe that it triggered a red alert in many areas with wind speeds of almost 200 km/h and high levels of destruction. There is a possibility of breaking wind and low pressure records.

Storm Ciarán triggered alarms in several countries in Western Europe, which braced for storms and heavy rain on their Atlantic coasts from Wednesday night. In France, the national agency MeteoFrance warned that the storm could cause wind speeds of up to 170 km/h and waves of up to ten meters, especially on the coasts of Brittany and Normandy. The departments of Finistere, Cotesd’Armor and Manche, located on the Atlantic coast, are on alert, the agency said.

In the UK, Met Office representative Kate Marks reported that there could be “significant flooding” and urged motorists to avoid these regions. “Some areas of south Wales and southwest England could receive 80mm of rain,” predicted Dan Suri of the National Weather Service.

Significant rainfall is also expected in the northeast of England, Scotland and the east of Northern Ireland over the next two days. Ciarán arrives in the UK less than two weeks after flooding caused by Storm Babet, which killed five people.

In Belgium, authorities declared an orange alert for the Flanders coast and a yellow alert for the rest of the country, urging the population to exercise caution. The cities of Brussels, Antwerp and Liège announced the closure of parks from this afternoon. Trains will run more slowly tomorrow and delays are expected, the national operator said.

In Spain, authorities in Madrid urged drivers to be careful entering and exiting tunnels. They also recommended avoiding walking under trees. The national weather agency has issued a storm warning for the regions of Galicia, Cantabria and the Pyrenees.

Storm Ciarán is a bomb cyclone expected to move across southern England and northern France from Thursday morning. It could set a record for the lowest air pressure recorded in the region in the last 200 years. The strongest wind gusts of 140km/h were forecast south of the UK in the English Channel on Wednesday afternoon.

A cyclone is the general name for any storm in which winds rotate around an area of ​​low pressure. A bomb cyclone is a storm in which the air pressure in the center drops very quickly, resulting in rapid or “explosive” intensification as the decreasing pressure creates higher wind speeds. Specifically, these are storms in which the pressure drops by 24 millibars (or hectopascals) or more within 24 hours. The term bomb cyclone is used only for extratropical or midlatitude storms, not for tropical cyclones such as tropical storms or hurricanes.

Numerical models suggest the possibility of a condition called a “sting jet” heading towards the English Channel, affecting the coasts of the south of the UK and northern France. Sting jets are known to cause the most violent storms in Europe during the fall and winter months, with maximum wind gusts reaching 100 mph or more.

A sting jet is a narrow core of violent winds that forms within rapidly intensifying extratropical cyclones in the North Atlantic. This leads to strong wind storms towards the surface. These jets are associated with the strongest and most destructive wind storms, with violent hurricaneforce winds being the most noticeable events.

The decisive factor for the formation of the bomb cyclone and its great intensity is an intense jet stream in the North Atlantic between North America and Europe. Impact of large temperature differences between Canada and the United States. Within this process, Ciarán quickly goes deeper explosive cyclogenesis or meteorological bomb.
