prognostic chart

Wave prognostic charts show the expected sea state at some future time.

The forecast map showing the state of the atmosphere at a future time is called a prognostic chart.

Around 1950, a good surface prognostic chart was considered to be one whose isobars were in the correct location.

Prognostic charts are maps which display what the weather is expected to be like at a future time; in other words, a forecast map.

They are similar to a prognostic chart in the USA.

Prognostic charts generated by computer models are sometimes referred to as machine-made forecasts.

The visual output produced by a model solution is known as a prognostic chart, or prog.

Marine weather warnings and forecasts in print and prognostic chart formats are produced for up five days into the future.

Errors with prognostic charts can be determined either via absolute error, or by considering persistence and absolute error combined.

Surface weather prognostic charts for mariners indicate the positions of high and low pressure areas, as well as frontal zones, up to five days into the future.

Ensemble spread is diagnosed through tools such as spaghetti diagrams, which show the dispersion of one quantity on prognostic charts for specific time steps in the future.

Within the United States, manual prognostic charts generated by the National Centers for Environmental Prediction have special symbols which require interpretation.

For purposes of severe weather, prognostic charts can be issued to depict current weather watches, convective outlooks for thunderstorms multiple days into the future, and fire weather outlooks.

Manual prognostic charts have special symbols which require a legend or previous knowledge which depict tropical cyclones, turbulence, weather fronts, rain and snow areas, precipitation type and coverage indicators, as well as centers of high and low pressure.

Prognostic charts can be made of isentropic surfaces (along a certain potential temperature surface determined in degrees Kelvin) in regards to moisture advection, mean temperatures at the surface, mean sea level pressures, and precipitation either for a single day or multiple days.
