Most marine forecasts give you a generalised wind forecast in the morning or the afternoon. PredictWind shows wind weather updates every hour, with a wind speed and direction map for your entire local area. The detail you can see in the marine forecast can help you plan your trip or possibly help you win your next yacht race. Check our wind forecast coverage of your local area.
A weather model is only as good as the information entered into the model. PredictWind uses two data sources for the model producing two alternative forecasts for comparison. If the two models are saying the same thing then you can have a higher degree of confidence in the forecast.
The initial conditions files are entered into the model. The files can be comparable to a 'photographic' snapshot that contains the current state of the Earth's atmosphere. PredictWind uses two sources for these files (from the USA and Canada) so you have a comparative result to give you confidence in the forecast.
Imagine dividing the atmosphere into 50km x 50km square grids over your local area. These initial conditions files step forward in time to create a 5 day forecast. For each 50km x 50km square region the model uses a complex equation to calculate the meteorological fields such as wind, temperature, humidity, pressure, rain and their interaction.
This process is then repeated for the 8km model run, though it is 'nudged' by the 50km model run.
Finally the 1km resolution model is completed, which is 'nudged' by the 8km model run. Significant computing resources are required to run the model in this configuration for all the PredictWind locations around the world.
Wind forecast maps and graphs and text are generated for the 20,000 worldwide forecast locations.
This process is repeated automatically every 12hrs for both initial sources (i.e. 4 forecasts every day). There is no historical data involved, so each 12hr forecast is independent from the previous.
All weather models use different physics, set up parameters, and many complex equations to calculate meteorological data such as wind speed, direction, temperature, pressure, rain and cloud.
The model used is exclusive to PredictWind. It has been developed over 25years by a team of research scientists, and has some unique features including a stretched grid. This stretched grid is the framework for the 50/8/1km resolution modelling. This enables the model to run without any boundaries, and is thus less constrained than other models that usually require significant damping. This sophisticated approach often reflects considerable variability in wind speed and direction, and is an advantage over other models.
