Percentile
|
|
|
|
A value below which a specified percentage falls (for example 90%). For example, in the weather generator output, the 90th percentile daily-maximum temperature is that which is exceeded on only one in ten days. See quantile.
For the marine projections however, the percentiles that are provided with the sea level and storm surge height projections indicate the percentage of model simulations that simulate the nth percentile value or less, but cannot be interpreted in the same way as the weather generator percentiles.

In detail
|
UKCP09 projects changes in extremes that are based on the 99th percentile, or the value that is exceeded on only one in one hundred days. This roughly corresponds to one day per season, meaning that UKCP09 provides probabilistic climate projections for variables such as the warmest day of the summer and wettest day of the winter.
For the sea level rise (SLR), and storm surge height projections, the percentiles represent the percentage of model simulations that project a value less than or equal to the nth percentile, and contain no information on the frequency of exceedance of that value. For example, the SLR 95%ile does not mean that SLR will be greater than that value 5 times in every 100 years.
