Explaining the Swirl of Wildfire Smoke
In recent years, smoke from powerful wildfires has raised questions among atmospheric scientists by always swirling in the same direction. The confounding structures were observed in the stratosphere, where smoke injected at around 15 kilometers in altitude absorbed sunlight and rose further, up to about 35 kilometers of altitude. The rising column of fluid would stretch, causing any residual rotation to get stronger and form vortices.
None of this was a surprise. What was surprising is that all of the observed vortices were anticyclones, when theory–at least for a heat-driven vortex from a stationary heating source–called for a cyclone-anticyclone pair.
Researchers looked at how a self-heating (and, therefore, moving) source would rotate. They concluded that this, too, would create a pair of vortices–one cyclonic and one anticyclonic–but the anticyclone would be stronger than the cyclone that trailed behind it. By further considering the vertical shear the vortex pair would encounter, the researchers found that the trailing cyclone could get stripped away, leaving behind only the anticyclone–matching our wildfire observations.

Changeable weather in Latvia: from sleet to a sunnier weekend
On Tuesday, skies will remain cloudy, though the sun will appear in some areas. At night, temperatures will…

Mission: Anticyclone (if the machine translation is to be believed)
I'd characterize this as "where Japan (the band) meets High Life, in Siberia"--maybe? Also some Howard Devoto influence, maybe

🌥️☀️🌧️L'#anticyclone sur l'océan #Atlantique devrait progressivement se rapprocher de nos contrées ce #weekend. Nous serons donc en bordure avec un temps #calme et #agréable à l'ouest, mais un temps #humide et bien #frais à l'est.

🌫️☀️La #France sera coupée en deux ce #weekend entre la #grisaille au nord et le #soleil au sud proche de l'#anticyclone où le ressenti sera très #printanier. Globalement, nous serons toujours entre 3 et 5°C au-dessus des normes. 🌡️

Today's weather charts show a #high #over Great Britain .
Suddenly I started believing on that climate change thing.
