Collection of code and presentations for the RP Rainfall Extremes in CLEX The project Homepage can be found on GitHub-Pages
This projects investigates how well convective extreme events are captured in high resolution models ( ≈ 1.5km to ≈ 150m). For this purpose the eight consecutive days of strong island thunderstorms events in the Monsoon break period over the Tiwi-Islands in Northern Australia. For a fact the local convective systems forming in the afternoon over the islands are the worlds most consistently occurring extreme events in the world Crook, 2001. Named by pilots during the Second World War, the recurring position of the thunderstorm made it a navigational beacon for pilots and mariners in the region. Hector is known to be initialised by local forcing, that is colliding sea-breeze fronts fronts over the islands.
Since the late 1980s the thunderstorm has been the subject of many meteorological studies, and this study is no exception. Yet, here we take the recurrence of the island thunderstorm as a proxy for locally forced convective extreme events in general and study the ability of the UK Met Office's unified model (UM) a limited area numerical weather forecasting system at different resolutions to represent extreme events.
The following collection of jupyter-slides shows the results of the above mentioned model study:
- Comparing simulated rainfall to observations: Area averaged rainfall and diurnal cycle. Timing of rainfall and distribution of extreme events. Presentation
- Investigation of Storm-Tracks: Storm duration, Intensity and Size. Presentation
- Including more observational periods to the Storm-Track analysis via bootstrapping different periods Presentation
- Slides containing the latest results of the Study. Presentation
- Introduction for MPI. Presentation
