To get weather and climate forecasts right, we need to think much smaller. Think of it in terms of space. Many climate models break the Earth into a grid, with each square 100 km, or 62-ish miles, a side. Smaller storms are averaged out. The small-scale landscape features that drive convection, or cloud formation, aren’t considered. But, without taking actual landscape data and smaller clouds into account, forecasts and climate models won’t be accurate. They’ll think too big and miss too much.
