CLEX researchers used data from a wind profiler radar pair at Darwin, Australia, to determine the characteristics of individual up- and downdrafts observed at the site. They found updrafts with 5km vertical heights with extreme rain rates.

Research brief: Ring like structure in cyclone leads to rapid intensification of surface winds

The most intense and destructive tropical cyclones generally go through a period of rapid intensification, where "rapid" means that the near-surface winds increase by more than 15 m/s (54km/hr) in 24 hrs. However, the physical processes by which storms rapidly intensify are not well understood. This study uses very high-resolution simulations with the UK Met Office Unified Model of the 2016 north-Pacific tropical cyclone, Nepartak, to explore the processes responsible for its rapid intensification.

Research brief: Tropical rainfall modelling errors decrease slowly, but storm resolving models may be the future

An international team including CLEX researchers examined models used by the Intergovernmental Panel for Climate Change (IPCC) over three model phases linked to IPCC reports – CMIP3, CMIP5, and the most recent, CMIP6, to see if they improved representation of tropical rainfall.
