Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government how they monitor the accuracy of weather forecasts issued by the Meteorological Office; and whether the accuracy of forecasts has (1) increased, (2) decreased, or (3) remained the same during the last five years.

The core task of the Met Office is to deliver the Public Weather Service (PWS). The PWS Customer Group (PWSCG), which has an independent chair responsible to the Minister of State for Universities, Science, Research and Innovation, monitors the delivery of the PWS against agreed performance indicators and targets, including the accuracy of public facing forecasts.

Over the last 5 years, the PWSCG has set targets each year for the accuracy of forecasts for maximum and minimum temperature, 3 hourly temperature, wind speed and wind direction at days 1, 3, and 5 ahead. During this period the accuracy of all these forecasts has increased.

In addition, the Met Office has a performance indicator that compares the accuracy of its global forecast model against other global modelling centres to demonstrate that it is maintaining its position in global forecast accuracy. Over the last 5 years the Met Office has maintained its position as the leading national meteorological service.
