The Met Office has been producing and verifying short-period (up to 5 or 6 days ahead) forecasts for every tropical cyclone since 1988. Verification of the performance of the global model in predicting tropical cyclone tracks has been routinely published on a monthly and seasonal basis during that time.
The links below show the forecast verification for all tropical cyclones during the last couple of seasons. The 'Observed and forecast tracks' links show forecast tracks for individual tropical cyclones accompanied by comments on the Met Office global model performance. The 'Seasonal verification reports' links show the global model's performance over the season as a whole. The 'Forecast error graphs' links show the long-term trend in track forecast errors since 1988 for various ocean basins as well as comparisons between the Met Office model and other forecasts.
For verification statistics from seasons earlier than those presented here please email email@example.com. For information on current tropical cyclones go to the tropical cyclone warnings and guidance page.

Method used to verify the forecast tracks of tropical cyclones in the Met Office global model.
From 1993 to 2008 the Met Office issued a document entitled "Monthly Summary of Tropical Cyclone Activity and Forecasts" which was sent to many individuals and meteorological centres around the globe with an interest in the forecasting of tropical cyclones. It contained information on the month's tropical cyclone tracks and statistics and charts relating to the performance of the Met Office global model in forecasting the track of each storm. The last edition of the monthly bulletin was published in December 2008. Editions for 2007 and 2008 are included below, but these links will be removed in the near future.
