DANA gave a truce to Valencia after hitting it with all his might, but now it’s the turn of other regions of Spain. Although such a dramatic situation as yesterday is not expected, in the northeast and southwest of the peninsula There will continue to be very heavy rainfall and some extreme weather conditions. For example, in Barcelona all beaches were closed due to both rain and risk of tornado.
DANA shouldn’t surprise us. Just yesterday, several tornadoes were recorded in Valencia. In fact, although it may seem very strange to us that there are tornadoes in Spain, This is not at all exceptional.
Despite this, they seem to reach us more and more often. Climate change is bringing us much more DANA rain and a greater frequency of extreme weather events. It’s just begun. At the moment there is only set your alarms on time. Barcelona already knows what can happen. Let’s hope they heed the warnings. At least more than the Valencian businessmen who sent their employees to work.
Why do tornadoes form?
It is estimated that each year between the peninsula and the Balearic Islands there is usually from 22 to 29 tornadoes. The three areas where they most often occur are: Catalan coast, Balearic Islands and Gulf of Cadiz. Therefore, people in Barcelona are already familiar with them.
As explained in eltiempo.esTornadoes typically occur in configurations where there is a trough at the surface and a trough at the top, oriented south to north. For my part, depression This is the rise of warm, moist air masses along an elongated zone of low atmospheric pressure located between two areas of high pressure.
In addition to all this, for tornadoes to form there usually needs to be a lot of water vapor in the lower atmosphere, as happens in the Mediterranean, especially as temperatures rise. There must also be a large change in wind direction and/or speed. This is what is known as shift.
All this is conducive to atmospheric situation created by DANA. Especially in the regions that we have already mentioned. For this reason, DANA, which caused so much chaos in Valencia, caused tornadoes there and may have also sent them through Barcelona.
Other consequences of DANA in Barcelona
As explained in Ambulance, Meteocat issued a warning risk 6/6the largest in existence. The reason is both the possibility of a tornado and the possible hail is falling. Besides the rain, which could cause flooding, of course.
Hail is expected to reach diameter more than 3 centimeters. This is enough to cause a lot of property damage as well as personal damage. This is why the public is advised to leave their vehicles safe, avoid placing valuables in patios and gardens and, of course, stay home until DANA is completed. If everything goes according to plan, we only have 24 hours left with her.
