It is more difficult to forecast the weather at some airports than others and at the more difficult locations to forecast for the proportion correct will tend to be lower.

is the specification of total rainfall for different durations and probabilities – called ‘Depth Duration Curves’ (spanning 1, 3 and 6-hour events for 3.3%, 1% and 0.1% annual probability). This first case study outlined how a user could recreate these curves for present-day and future periods using

averaged precipitation for July- August-September (JAS) from forecasts initialised around April. The forecasts in Figure 1.1 are presented as probabilities of quintile categories of total JAS rainfall for each of the three regions. The quintiles are evaluated using observed JAS rainfall data for 1961
