Speedwell: The ZigZags ( Forecast Model Comparison )



Frame-by-frame real-time graphical and numerical presentation of the actual and change in forecast (ECMWF and GFS forecast models). Updated as each time step of the model is released.

Speed, Speed, Speed,...

The proximity of Speedwell’s London office to ECMWF coupled with streamline model processing on dedicated servers results in fast delivery of ECMWF forecast changes to the market. Client feedback indicates that we are usually ahead of the competition.

Understandable Output

The ZigZag product has been designed with input from traders. The goal is to present the information in a straight-forward manner: the key information: “warmer or colder...?”

Station Forecasts (cities) or Regions

Station forecasts are based upon the model forecast for a particular point on the earth. Regional forecasts combine model outputs within a given geographical area. Regional forecasts include US power regions and European countries.
Regional Analysiss Regional analysis (such as the ERCOT region shown above) utilize a basket of forecast grid points located within a given area.



Warmer or Colder?

Here showing ZigZags Deltas presenting difference from previous model run. In this example, the ECMWF output shows signifi-cantly cooling for the ERCOT region
View the difference between successive model runs or previous runs: Diff 6hr (for GFS only), Diff 12hr, Diff 24hr, Diff 48hr, Diff 72hr
View the model difference (ECMWF operational and/or ECMWF en-semble and/or GFS Ensemble, TMax, TMin, TAvg, or Precipitation). This example shows difference of each model as compared with the run 24-hours ago.

The ZigZag Grid updates MULTIPLE sites showing the change in daily Tmin TMax as each day becomes available. So the table fills from left to right.

[Note that a downscaled forecast re-quires all of the time frames to be deliv-ered. It is therefore much slower. ]
