Nowcasting Mesoscale Phenomena

Short-range forecasting or nowcasting is based upon the ability of the forecaster to assimilate great quantities of weather data, conceptualize a model of the environment, and extrapolate this forward in time. Frequently this is done just to describe existing conditions, and thus has the term “now-cast” originated. Since the time scales are essentially the same for short-range forecasting and nowcasting (the same processes are used for both), the terms are used here interchangeably. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
