The Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS®), developed and run by the Naval Research Laboratory in Monterey, CA, is a numerical model used for wind nowcasts and forecasts. The implementation of the model used here has a fine spatial resolution of 4 km and covers the coastal ocean from Oregon to Mexico.

What is an atmospheric model?
An atmospheric model is a type of numerical model that uses mathematical equations representing the physical behavior of the atmosphere to make predictions of either past present or future atmospheric conditions.
What is a nowcast?
A nowcast defines the current atmospheric state over the model domain. Every 12 hours (at 0000 and 1200 UTC) the model takes all the available observations for that hour and interpolates them, together with the previous model forecast, to the evenly spaced model grid.
What is a forecast?
After determining the current atmospheric state (nowcast), the model then projects the atmospheric fields forward in time generating a forecast.
Why use the COAMPS model?
Models of this type, as opposed to global atmospheric models, include both the physics and the detailed terrain that make it possible to realistically simulate the complex atmospheric features found in the nearshore zone.
