The forecasts are designed specifically to forecast the impact of CB on aviation in the London Terminal Manoeuvring Area, known as the London TMA, and are produced by meteorologists at the Met Office. Challenges faced in developing the verification system resulting from the subjective nature of the forecasts themselves and the limitations of the data (from the UK Air Navigation Service Provider UK ANSP) available to assess the true impact on aviation are discussed. The forecasts include the likelihood of medium impact events as well as the likelihood of high impact events resulting from thunderstorms. A unique approach has been taken to verifying these forecasts which has involved working closely with the primary user, the UK ANSP. An objective verification system has been developed to assess the forecast accuracy across all lead times for high and medium impact events. This system provides the tools necessary for routine, year-on-year evaluation of the forecast performance.
