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.

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 futureOctober 23, 2020 10:24 am Comments Off on 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.
Organised nighttime thunderstorms can sometimes occur without a surface cold pool. CLEX researchers investigated how this could occur and still support storms.
Thus study used satellite scatterometry to measure the horizontal component of winds over the sea surface in the Maritime Continent. It combined data with scatterometer to give additional insights into gravity wave structure in this region.
