[1/2] We’ve released a new version of the factsheet on #Birchgletscher, the Swiss glacier that collapsed on 28 May 2025 following heavy debris loading from Kleines Nesthorn -- and some first field impressions that we were able to collect yesterday 🗂polybox.ethz.ch/index.php/s/ea…

Eruption am Ätna bis 6.5km Höhe ist nach VAAC schon wieder vorbei, dafür viel Waldbrandasche aus Kanada über Grönland-Island und Saharastaub aus Afrika über der Karibik 😲

BREAKING: A Florida meteorologist just went on air and said he can’t accurately report the weather anymore, because Trump’s DOGE cuts gutted the satellite data he relies on. We’re not just defunding science, we’re sabotaging public safety. And for what? So a billionaire

The real-time forecasts launched by NSF National Center for Atmospheric Research scientists are more fine-scale than other real-time global weather models, and can lead to significant advances in worldwide weather prediction.

Looks like the ECMWF seasonal model is indicating the development of a Central Atlantic Nino, meaning the +SST anom. are focused from around 30-15W longitude instead of in the Gulf of Guinea (10W-10E).

Check out just how far wildfire smoke has spread! Since late May, smoke has swirled more than 5,000 miles from Canada to Russia, according to my analysis using Copernicus ECMWF data. Smoky skies have also been spotted in parts of Europe, Greenland and the Arctic Archipelago.

Yesterday's ECMWF seasonal forecast certainly raised the stakes for unusual heat across central and southern Europe. For this region, it's the warmest Jul-Sep forecast in the model's history (June init). However - there isn't much skill beyond simply the long-term trend.

Freezing level peaked at 4537 m today in the #alpeadria This might be the highest ever recorded freezing level in June after 4242 m in 2015 Radiosonde measurements for atmospheric temperature profiling have been conducted daily since the 1970s

#Barbara is now a #hurricane - the first hurricane-strength tropical cyclone of the 2025 Northern Hemisphere season. Barbara is the latest 1st Northern Hemisphere hurricane since 1993.

Das müsst Ihr lesen!😂😂😂 Grok erklärt, in bayerischem Dialekt, Unwissenden, wie Monika Gruber, warum #Kondensstreifen entstehen. #Meinungsfreiheit

Atlantic seasonal #hurricane forecast update from Colorado State University continues call for an above-normal season: 17 named storms, 9 hurricanes & 4 major hurricanes. Relatively warm Atlantic and likely absence of #ElNino are the primary factors. tropical.colostate.edu/Forecast/2025-…

From doing a quick perusal, I am honestly pretty impressed by this new AI TC model that Google is running. This shows more intensity skill in retrospective mode than any AI system I've seen so far. I'll be very curious to see how it does in "real-time" this year (that's always

Our #CopernicusAtmosphere aerosol optical depth forecast initialised on 11 June showed a complex mixture of aerosols over Europe in recent days with smoke transport from Canadian wildfires interspersed with a plume of Saharan dust. See the latest charts: atmosphere.copernicus.eu/charts/package…

Latest SST maps show strong anomalies (around 3ºC in extense areas) in the western Mediterranean (AVHRR_OI data) with SST values between 24-26ºC (Copernicus high resolution SST). (1/2)

Wo immer ein russischer Soldat seinen Fuß hinsetzt, ist es unser Land. [Putin] Wer nach solchen Äußerungen noch an den Nutzen von Verhandlungen glaubt, hat etwa die Auffassungsgabe einer Zimmerpflanze mit rheumatischen Beschwerden.

I updated the PolarWx model forecast vs. ERA5 records map to include 2024 in the ERA5 record period (1950-2024, previous maps were 1950-2023). The upcoming East US ridge will set near-record annual maximum geopotential heights... the previous record was set in June of last year.

got albedo? Darker than normal areas are red colors, consistent with melt being above usual this year so far

The tongue of Rhone #Glacier ten days after my last visit. Can you guess how much ice melted away? 1️⃣ meter in terms of thickness! 1️⃣0️⃣ days... And that's just the beginning of the summer season. We know the times are bad for the ice, but still it is hard to accept these numbers!

Hunting the extreme year 2022... Yes, I'm really worried about the current state of Swiss #glaciers! After a dry winter, the scorching heat of the last weeks pushes glaciers towards another black year. Hoping for some cooling but the summer has only just started VAW Glaciology

#Hitze lässt Schnee und Eis in den Alpen schmelzen. Das Messfeld an der Zugspitze wird bis morgen #ausapern. Der Negativrekord aus 2022 (19.06), wird dank des kühlen Mai's aber nicht erreicht. Ganzjährig Schnee lag auf der Zugspitze übrigens das letzte mal im Jahr 2000.
