believe the forecast(s) to be, based on feedback from market research. Comparative accuracy refers to how accurate the Met Office is compared to other weather providers, and this can be judged via actual accuracy measures or and perceived accuracy measures. However, the definitive comparison is based

+/- 1.5 m/s in places (not shown). The direction of change in future wave climate is consistent, with the mean SWH seen to reduce in both configurations. Stronger changes are seen in the regional model than the global model. Additional simulations under RCP4.5 (not shown) show similar patterns

and working change almost overnight, with uncertainty and disruption affecting us in ways we could never have predicted. Two examples of COVID-19’s impact on Met Office operations spring to mind. Firstly, due to reduced aircraft flying, there were fewer observations to feed into the Numerical Weather

”. A subtle reframing of the manner and format in which messages are communicated can have a significant impact on whether the information is well-received and acted upon. One important point in relation to information framed in terms of losses is that it is important to also highlight action(s) that can

represents how well the weather forecast at a particular location represents the true weather conditions observed at that location. Perceived accuracy represents how accurate Met Office users/customers believe the forecast(s) to be, based on feedback from market research. Comparative accuracy refers
