WeatherFlow offers our customers the opportunity to view many different models. Why so many? We want you to have the same tools that professional meteorologists use to make a forecast. Each model has different strengths. Meteorologist are trained to know how each model acts for certain atmospheric situations. By watching and comparing these models you can determine and choose which one is best for your particular area or situation. Here's a look at a selection of our available models to help you choose which one is best for your application.
Quicklook/Plus Forecast Model
Quicklook combines the best features of available models for an area to give you a complete forecast table. You can access this forecast product across the globe. Our Premium members (Free members have access for a limited time) have the option to overlay the Plus model for the first 18 hours. Plus gives you the best of the best. This model is frequently updated with weather details as low as 2 km. If you can’t wait for the next forecast run don’t worry, you no longer need to wait more than one hour because Plus updates hourly. Choose this model when you need to make weather decisions for the next 12 hours or for small areas.
Check the box to view the Plus forecast.
These model take a lot of computing power because they resolve the features on a small scale. Consequently the models are only run for small areas and for shorter time frames. Use these models when looking for information for small features such as beaches and for the short term.
WF-WRF - WeatherFlow Weather Research and Forecasting Model - A Weatherflow exclusive. This model is available to our premium customers in limited areas. The resolution varies from 1 to 9km. We use our own proprietary network of sensors to seed the model which enables the model to initialize much closer to reality than other high resolution algorithms. WF-WRF is currently run out up to 40 hours, 4 times daily. This is a great model to use to identify where localized sea breezes will develop.
WRF - The Weather Research and Forecasting Model - Is the product of a multi-agency and university collaboration. We deliver this to you with a 5 km resolution for the continental United States and the surrounding coastal regions.
ARW 5km - Hawaii Model - It is another model run from UCAR incorporating several different models in an attempt to get better accuracy in Hawaii and Alaska. The higher resolution at 5km is thought to allow this model to better pick out the intricacies of the islands.
NAM - North American Mesoscale Model - This was the former ETA model and is delivered on WindAlert products with a 5km and 12km resolution and delivers you forecast information for the next 78 hours. It is only available across North America and for the surrounding coastal regions.
GFS - Global Forecast System - It is run four times a day (00Z, 06Z, 12Z, 18Z) and produces forecasts up to 16 days in advance. It is run at roughly 50km resolution. However, the spatial and temporal resolution is reduced as the model is further out in time. (The forecast produced beyond day 7 is generally not trustworthy. It produces a forecast for every 3rd hour for the first 180 hours.
CMC - Environment Canada Global Model - This is another model which will give you a forecast for all points on the globe. The resolution is approximately 100km resolution and runs out 138 hours.
