Storm Desmond
Impact of starting date and lead time
Experiments for Storm Desmond are initialized from 5 dates: 1, 2, 3, 4, and 5 December 2015. The major events related to the storm (high precipitation, wind gusts) happened on 5 December. Consequently, forecast lead times of 96-120 hours, 72-96 hours, 48-72 hours, 24-48 hours, 0-24 hours are studied, respectively.
The PDF documents below are prepared for 9 variables: mean sea level pressure, 2-meter temperature, 24-hour precipitation, 3-hourly 10-meter wind gust, 850 hPa temperature, 700 hPa relative humidity, 500 hPa geopotential, 250 hPa and 100 hPa wind fields. The figures of experiments are organized in 5 columns according to the 5 starting dates and 9 rows for the 3-hourly outputs between 00 UTC on 5 and 0 UTC on 6 December. The only exception is the precipitation where the daily amounts are located in one row. Both the corresponding ERA-Interim and ERA5 fields are displayed as reference (please note that ERA-Interim re-analyses are available with 6-hour frequency).

Mean sea level pressure | 2-meter temperature | 24-hour precipitation |
3-hourly 10-meter wind gust | Temperature at 850 hPa | Relative humidity at 700 hPa |
Geopotential at 500 hPa | Wind speed and direction at 250 hPa | Wind speed and direction at 100 hPa |
Impact of initial condition
Experiments for Storm Desmond are initialized from ERA-Interim and ERA5 re-analysis datasets for 3 and 4 December 2015. The major events related to the storm (high precipitation, wind gusts) happened on 5 December. Consequently, forecast lead times of 48-72 hours and 24-48 hours are studied, respectively.
The PDF documents below are prepared for 9 variables: mean sea level pressure, 2-meter temperature, 24-hour precipitation, 3-hourly 10-meter wind gust, 850 hPa temperature, 700 hPa relative humidity, 500 hPa geopotential, 250 hPa and 100 hPa wind fields. The figures of experiments are organized in 2 columns according to the 2 starting dates and 9 rows for the 3-hourly outputs between 00 UTC on 5 and 0 UTC on 6 December. The only exception is the precipitation where the daily amounts are located in one row. Both the corresponding ERA-Interim and ERA5 fields are displayed as reference (please note that ERA-Interim re-analyses are available with 6-hour frequency).
