Reversal pattern in Europe?
-
Credit: tropicaltidibitsWe are experiencing a long and intense hot phase in Central Western Europe caused by the infamous atmospheric figure called omega blocking.
A powerful African high pressure, fed to the sides respectively by an intense Atlantic depression and a cut off present on the Balkan peninsula, has led to the overcoming of several heat records.
In these days the contextual expansion of a promontory of high pressure of Azorean matrix and the formation of an intense low pressure vortex, filled with cold air,
on the Scandinavia will determine a general filing of heat peaks with the first strong thunderstorms which, already during today, they will affect several states of central and eastern Europe, with large hailstorms and gusts of wind.
While on the one hand most of the Central European states will experience a large thermal drop on the other, the states facing the Mediterranean will have to wait at least one more week.
The main global models are beginning to give great indications on a possible reversal pattern by the end of the first decade of July on Europe.
An important help will be given by Mjo (madden julian oscillation) which represents the displacement of tropical convection maxima and is therefore able to modify the undulatory trend of the circulation of mid-latitudes.
The diagram is made up of 8 phases that represent the displacement of the convection maxima between the continents. To be forced, the line must exit the circle, in fact the further away from the circle the greater the magnitude. Each phase strengthens differently depending on the area and the Enso signal (nino, nina and nada).Thanks to an important work done by the scientific committee of meteonetwork that has correlated the phases of the Mjo with the signal Enso (nino, nina, nada), we can understand what will be the trend for the next days with the shift of the convection maxima in phase 1 .
The resulting pattern would represent an inverted omega with tendency to heat waves on the eastern countries facing the Mediterranean and high blocking pressures in the Atlantic.
Wr1 patternIn short, a summer that started very strongly but could suffer a violent stop, with temperatures below average and massive thunderstorms

Interesting!
Should be good to give more information about the map at top of article.
