    “[The Google WeatherNext AI team] are showing how the WeatherNext AI model from Google DeepMind and Google Research has achieved state-of-the-art accuracy in predicting a cyclone's track, intensity, and wind structure. On average, the WeatherNext Cyclones model gives forecasters an extra day’s worth of predictive accuracy- delivering an advance equivalent to roughly a decade of historical meteorological progress 🌀
    Here is how WeatherNext is transforming cyclone forecasting:
    • Gaining an Extra Day of Advanced Warning: WN 3-day forecasts are as good as what prior models were able to provide for 2-day forecasts, giving critical time for emergency response.
    • Overcoming Traditional Trade-offs: WN bridges the gap between massive global atmospheric currents (which steer a cyclone's path) and fine-grained thermodynamic processes around its core (which drive its intensity) into a single AI model.
    • Unprecedented Ensemble Scale: Using Functional Generative Networks (FGNs), WN now generates 1,000-member ensembles in less than a minute on a TPU to capture rare, consequential tail-risks like sudden rapid intensification – which means forecasters can see a broader range of possible scenarios.
    • Real-World Impact: During the 2025 Atlantic hurricane season, the WN model helped the National Hurricane Center (NHC) make a historic forecast for Hurricane Melissa by predicting rapid intensification and landfall five days in advance.
    [The] teams are open sourcing the operationalized models (WeatherNext Cyclones and WeatherNext 2), alongside a compact version (WeatherNext 2-mini) that can run on a single TPU in a free public Colab notebook – all with a goal of empowering local organizations worldwide.
    Weather affects everyone. By combining advanced AI with the real-world expertise of human forecasters, we can build a collaborative ecosystem that saves lives and helps communities adapt to a changing climate…”

    “Hydroclimate volatility refers to sudden, large and/or frequent transitions between very dry and very wet conditions. In this Review, we examine how hydroclimate volatility is anticipated to evolve with anthropogenic warming. Using a metric of ‘hydroclimate whiplash’ based on the Standardized Precipitation Evapotranspiration Index, global-averaged subseasonal (3-month) and interannual (12-month) whiplash have increased by 31–66% and 8–31%, respectively, since the mid-twentieth century. Further increases are anticipated with ongoing warming, including subseasonal increases of 113% and interannual increases of 52% over land areas with 3 °C of warming; these changes are largest at high latitudes and from northern Africa eastward into South Asia. Extensive evidence links these increases primarily to thermodynamics, namely the rising water-vapour-holding capacity and potential evaporative demand of the atmosphere. Increases in hydroclimate volatility will amplify hazards associated with rapid swings between wet and dry states (including flash floods, wildfires, landslides and disease outbreaks), and could accelerate a water management shift towards co-management of drought and flood risks. A clearer understanding of plausible future trajectories of hydroclimate volatility requires expanded focus on the response of atmospheric circulation to regional and global forcings, as well as land–ocean–atmosphere feedbacks, using large ensemble climate model simulations, storm-resolving high-resolution models and emerging machine learning methods…

  6. A Walk in Night Fog

    Reading Time: 2 minutes

    Yesterday morning I woke and looked out of a window and saw fog. For some, the reaction is "oh zut alors" as we think that we're in for several weeks of being under the clouds, with the mountains as a weekend escape from a sun deprived time spent in fog.

    An Indirect Walk

    I took it as an opportunity. I could have walked from A to B last night. Instead I walked my usual walk. Along the way I looked for interesting photo opportunities. The fog was thick, and you could see water droplets floating in the air near lights.

    With some apartments, with especially brilliant lights there was an interesting line to demarcate where the light's rays could reach, and where it was out of range.

    The Cone of Light

    On the walk home I played with the flashlight and clouds. I noticed that I could indicate where I was, with a cone of light pointing down to where I was. I could also see clearly where the light no longer lit the droplets of water in suspension in the air.

    Now, back to the apartments. In some cases, where there was just one or two windows, the limit of lit and unlit fog was clear, and it made for an interesting sight.

    Apartments Lighting Water Droplets

    In one case the light from two apartment windows lit the sky behind a tree so well that it was nicely silhouetted against the night sky. There were several such opportunities.

    Another person noticed how these same light rays were visible where light from a street lamp split the light rays, highlighting what remained in shade, and what was lit. If I had taken the time I could have got a similar photo on numerous occasions.

    And Finally

    Whilst it is easy to see fog in the morning, and regret that it is foggy, fog is a good opportunity to get original photos. It is as good as when we see a beautiful sunrise or sunset, except that the opportunity to take photos lasts for an entire day and into the night. As I write this we have dull lighting today, great for portraits, but flat and uninteresting for landscape photos.

  8. Eighty-five percent of the #Earth’s air resides in the lowest layer of its #atmosphere, or #troposphere. Yet, major gaps remain in our understanding of the #atmospheric #chemistry that drives changes in the troposphere’s composition.
