After another spring session is outdated, winter returns to Spain starting tomorrow. February 22. According to the publication State Meteorological Agency (AEMET)arrival polar jet which will move an anticyclone causing greater atmospheric stability, with temperatures well above normal for these dates.
This will lead to a sudden change in weather: low temperatures, strong winds, rough seas and precipitation that may turn to snow in much less quantities than usual.
While it’s impossible to predict the weather ahead of time, it’s possible that we’ll have some… heavy storm. Therefore, it is necessary to clarify many concepts, especially two. What is a polar jet and a strong storm?
The polar jet that will change everything
defined as polar jet a very intense air current that concentrates at high levels of the atmosphere, approximately Height from 9 to 12 kilometers. He, as we will see tomorrow, is behind the changes between storms and anticyclones, since he will be responsible for moving the anticyclone and making room for the storm.
He anticyclone This is an area of high pressure. That is, an area in which the air pressure around it is lower. Instead of this storm It’s quite the opposite. An anticyclone is usually associated with what we call good weather, and a storm with bad weather. Although it should be clarified why we classify the weather as bad or good, that is another question.
As for severe storms, these are those in which the pressure is particularly low, so the effects are much more intense, with strong gusts of wind and large amounts of precipitation. They usually happen very quickly, in which case they are also called explosive cyclogenesis.
In fact, it is this speed of their formation, coupled with the damage they can cause, that is why they are monitored very carefully, cataloged under their own names, just like hurricanes. If the coming storm is classified as a severe storm, it will be named Louis. This is the name that plays after Carlottain classification National Meteorological Services of South Western Europe.
What will happen in Spain
A new meteorological situation caused by the polar jet will begin February 22. It will start with a cold front that will enter the peninsula from the northwest, causing most of the rainfall both in this area of the peninsula and in the Balearic Islands. Then on the 23rd he will move to Mediterraneanwith very strong winds.
Winter conditions will cover almost the entire peninsula by the 24th, but a new storm on this day will worsen the situation. will enter via the Atlantic. Maximum temperatures, which so far reached 15-20°C, may drop to 7-10°C.
This is the forecast for now, although we have yet to see how things will develop. At the moment it seems that winter is returning, as it should be for this time of year.
