Latest SSTA data reveal persistently elevated Atlantic temperatures, alongside extreme warmth in the northern Pacific, Baltic, and Barents Seas.
However, a developing La Niña is evident in the eastern tropical Pacific, concurrent with a negative Indian Ocean Dipole (IOD).

Eine erfundene Korruptionsstory über Selenskyj ging von einer pro-russischen Zeitung in der Türkei aus, wurde von russischen Medien verstärkt, über MSN verbreitet und schließlich von einer US-Abgeordneten zitiert.

Autumn is peak season for fog, yet this morning’s distribution was complex:
fog (very low clouds, orange) blanketed the Swiss Plateau, while low stratus (low clouds, yellow) prevailed in the Alps and Ticino.

Our new study finds that the upper atmosphere is becoming more sheared and less stratified because of climate change. Both these changes are making the air less stable and more conducive to turbulence.

"Ultra" fish-(tropicla) storm Lorenzo rages in the tropical Atlantic, won’t even reach the Azores.
May briefly hit Cat 1–2 by Thursday, remnants afterwards drifting back to southwest on the northeast trade winds 😲

Dry and fine autumn weekend in Switzerland: overall up to 21.4 hours of sunshine on the highest peaks (e.g. Saentis) -
"nada" between central Switzerland (Lucerne) and Geneva!

High resolution images from satellite and from eddy-resolving ocean circulation models point to an ongoing decline of the Atlantic overturning circulation, a key ocean current for our climate. Read more about it in my new blog article. 🌊

Subtropical Storm Karen forms in the Atlantic Ocean north of the Azores, becoming the eleventh named storm of the 2025 hurricane season.

A subtropical cyclone is a system that has both tropical and extratropical features.

Autumn has arrived: extensive low stratus over the Swiss plateau, but also in intra-alpine regions (Grison, Valais) and even extending into the Engadin!
Elsewhere in the Alps, conditions remain sunny, clear, and warm, with the freezing level today and tomorrow at ~ 4,000 metres!

Wow, autumn-to-date mean temperature in Sodankylä, Lapland is currently a full two degrees (!) higher than the previous record.

In Sodankylä, records have been kept since 1908.

La Niña conditions are expected to continue through the December 2025 to February 2026 timeframe. A transition to ENSO-neutral conditions, meaning neither El Niño nor La Niña conditions, is most likely in the January 2026 to March 2026 timeframe.
(2/3)

A bar chart titled "ENSO Probabilities, Issued October 2025." It shows the percent chance of La Niña (blue), Neutral (gray), and El Niño (red) conditions for different three-month seasons from September 2025 to July 2026. The chart indicates a high probability of La Niña in the fall, decreasing over time, while the probability of neutral conditions increases beginning in January 2026.

Polar air, clear skies, and lengthening nights produced a cold Friday morning across Switzerland, with first frost recorded even in lowland areas (e.g., Ruswil, Lommis) and temperatures dropping to –8°C in the Engadine.
Such cold nights are less likely in October, per Zurich’s ensemble forecasts.
