Predicting the Unpredictable

At the Icelandic Meteorological Office on Bústaðavegur 7, a supercomputer is jointly operated by the meteorological services of Iceland, Denmark, the Faroe Islands, Greenland, the Netherlands, and Ireland. The British meteorological service may also soon join this collaboration. As of mid-June 2024, after formal operations began in March, highly accurate forecasts are now available for these six countries. The precise forecast lead time has now reached 72 hours for these meteorological offices. This signals significant benefits for transportation and anyone relying on weather information, especially in the northern regions with their often-treacherous weather conditions. The supercomputer processes real-time data every hour, collecting information to assess the likelihood of precipitation and wind speeds above specific thresholds. In the near future, these supercomputer forecasts will be accessible on the Icelandic Meteorological Office’s website. Initially, meteorologists on duty will use this information to provide accurate weather predictions for tomorrow and beyond, with a hundred percent reliability.
