Smart forecasters look at the entire universe of models together, and take their strengths and limitations into account when making predictions, while communicating uncertainty when models disagree. The NHC produces their forecasts using the data generated by models, and when they do they are able to consider how each model has performed in the past. Meteorologists record measurements about the atmosphere as it currently is and use that to simulate what could happen in the future according to the laws of physics. SERN DAMAGE PMT Weather observations (pressure, wind, temperature and moisture) obtained from ground sensors and weather satellites are fed into these equations. SHSN PAC center of the tropical cyclone.
The foundation for models are mathematical equations based on physics that characterize how the air moves and heat and moisture are exchanged in the atmosphere. CHANGE

STORM LAND NV Then there are mesoscale (fine scale) models, which hone in on more specific regions and tend to be able to forecast really small weather features, like thunderstorms, better than the global models. The two most popular U.S. mesoscale models are known as the North American Mesoscale Forecast System (NAM) and the High-Resolution Rapid Refresh (HRRR) model.
