(New Scientist) Look out, South Dakota and Nebraska – wild weather is on its way. That's the message from this example of the new super-detailed US weather forecast map, produced by the National Oceanic and Atmospheric Administration.
NOAA is combining detailed real-world weather data with models of how clouds and winds evolve, creating a weather prediction that is updated every hour. It has a resolution of 3 kilometres, four times better than previous systems. This allows meteorologists to pinpoint neighbourhoods under threat of tornadoes, snowstorms and flash flooding as well as alert airports and pilots to air turbulence and thunderstorms.
