Alain Protat

Principal Research Scientist

Current work and responsibilities

Alain leads the "Radar Science and Nowcasting" Team. Alain uses radars at different frequencies and on different platforms (ground, ship, aircraft, satellite) to better understand cloud and convection (storms) processes. Alain then exploits this better understanding of clouds and convection to evaluate and improve the representation of clouds and convection in numerical weather prediction and climate models.

Alain's current research activities are :

  • Analysis of radar-derived properties of tropical convection to inform a new cumulus parameterization.
  • Analysis of tropical convective cores to help update civil aviation regulation with respect to ice crystal icing.
  • Investigation of cloud processes responsible for the large shortwave radiation biases in climate models.
  • Analysis of hailstorm, tornado, and bushfire case studies: how can we improve early warning and post-event mitigation ?
  • Development of automated radar calibration techniques for the Australian operational radar network.
