  Presentation | December 2016 | External Use 1 The survey helps us to measure perceptions and allows us to monitor how perceptions change Purpose of the survey: 1. To measure performance against two KPIs (accuracy and usefulness) 2. To assess usage of forecasts amongst the public 3. To analyse the sources

  of the June temperature anomaly (relative to 1901-1930) in the reference region (5W-13E; 38-52N) computed with observational data from CRUTEM5 (black line) and the CMIP6 ALL (red lines) and NAT (green lines) simulations. The models were evaluated against the observations (Fig. 2) by applying a number

  in the changing likelihood of extreme heatwaves. Extreme events are defined as exceedances of the previous record anomaly of 4.126 0C (relative to 1901-1930) observed in year 2003. Temperature observations come from the CRUTEM5 2 dataset (Osborn et al., 2020) and cover the period 1851-2021. The model
