High-resolution global atmospheric model erases 'popcornlike' rain
Global climate and weather forecasting use predictive models that divide Earth's atmosphere into a grid, with each section typically covering tens to hundreds of kilometers. Now a new model, run by a team at the University of Tokyo, has narrowed this grid spacing to just 220 mete
