What if we could use satellite observations of cloud profiles to help determine the initial conditions on which weather forecasts are based? Recent results show that it can be done and that it would improve forecasts.
Sometimes even short-range forecasts go wrong, as in this example of windstorm Johanne, which affected Denmark a few weeks ago. Investigating cases like this is important for improving the forecasting system.
