fws-weather_forecasts

This data flow contains forecasts of weather variables, including temperature, pressure, wind speed, wind direction, humidity, precipitation, visibility, and light conditions as well as forecast data attributes. This data flow also contains advisories, watches, or warnings for weather related events. The weather forecasts are classified by meteorological scales, each of which cover a range of time and a range of space. The scales are miso (timescale of minutes to an hour before the event and horizontal scale of meters to a kilometer), meso (timescale of several hours before an event and horizontal scale of one to 100 kilometers), synoptic (a timescale of 12 hour to several day horizon and a horizontal scale of 100 to 5000 kilometers) and climatic (a timescale beyond synoptic and a horizontal scale greater than 5000 kilometers). This data flow consists of the following data items each of which is defined in its own DDE:

miso_scale_weather_forecasts
+ meso_scale_weather_forecasts
+ synoptic_scale_weather_forecasts
+ climatic_scale_weather_forecasts
