The greatest atmospheric ballet! Large, highly visible snow mesovortices rolling down a convergence band over Lake Michigan on 2024/01/19. Perhaps the most beautiful radar data NEXRAD has ever produced. This is a 14 hour loop showing the ridiculously high number of them that developed sequentially

Watch Gabrielle evolve from a lopsided tropical storm to a major hurricane in less than 48 hours.
Circle extends about 600 km from the storm center. Intensity values are interpolated to hourly resolution to match the infrared images, rounded to 5-kt increments in line with NHC precision.

Hoy es el peor día de la ola de calor en Zaragoza, superando +42ºC. Sin embargo, lo que más destaca son las mínimas: 7 potenciales días seguidos con mínimas +25ºC.
Hasta el año 2023, el Aeropuerto de Zaragoza no había registrado una mínima +25ºC.

The heatwave in Sodankylä has now lasted for 26 days.
This is probably not only the longest heatwave in Lapland, but also the longest heatwave ever observed in Finland.
Note that here a heatwave is defined with 3 consecutive days above 90th percentile, which is scientifically robust definition.

Si modificamos la temperatura de punto de rocío por la potencialmente observable (los modelos no resuelven adecuadamente la humedad) de 14ºC a 18ºC, el aumento de la energía es muy considerable (> 4000 J/Kg). Esto permite que la convección sea aún más severa con la WS de hoy.
