Laurent Labbouz

Postdoctoral Research Assistant

I am a postdoctoral researcher in the Climate Processes group, (sub-department Atmospheric, Oceanic and Planetary Physics) since spring 2014. I am involved in the EU FP7 project BACCHUS, the ERC project ACCLAIM and have also collaborations within the ECHAM-HAMMOZ community.

I obtained my PhD from the Blaise Pascal University in Clermont-Ferrand, France, in June 2013. I did my research in the LaMP (Clermont-Ferrand) and I worked mostly in the framework of the COPS (Convective and Orographically-induced Precipitation Study) campaign.

My research project is on the parametrisation of convection and convective microphysics in a climate model (ECHAM-HAM - CCFM), with a focus on the ice formation and the impact of aerosols. I am introducing new microphysics within CCFM and comparing the results of different schemes with observations and other models (WRF), showing the importance of capturing well the microphysical processes in order to accurately model aerosol-convection interaction.

Properties of the convective cloud spectrum such as the mass flux and the distributions of cloud top height and vertical velocity are also important for aerosol-cloud interaction and for climate. I investigate their sensitivity to model parameters and compare them with observations, in order to better understand the abilities and limitations of the model and to drive model developments.

I mostly use the Single Column version of ECHAM-HAM with forced advective tendencies, as it suits well for testing purposes and comparisons with local observations.

More details about my current research work can be found here.

This work is funded by the EU FP7 BACCHUS project and the ERC project ACCLAIM.

Previous work

During my PhD in the LaMP (Clermont-Ferrand, France) I have been working on the interactions between water vapour field evolution and the precipitating systems. I used GPS data for 2D and 3D (tomographic) water vapour retrieval, in the framework of the COPS campaign for case studies (Labbouz et al., 2013; Planche et al., 2013; Van Baelen et al., 2011). I have also worked on longer time-series in order to perform some statistical analysis, and to open pathways for other studies and possibly nowcasting (Labbouz et al., 2015).
I have also been involved in the reprocessing of a large number of grond-based GPS measurement, in order to provide a homogenous database to the community (Sguerso et al., 2015).

My Master project (LATMOS and UPMC, Paris) was on the inhibition of convection over the Vosges.

A few years ago, during an internship in the Laboratoire d'Aerologie (Toulouse, France), I worked on atmospheric electricity (links between lightnings and sprite formation) and I keep an interest for this topic

Research interests

My research interests (present, past and future work) include various aspects of atmospheric convection :

  • Parametrisation of convection
  • Impact of convective microphysics on the climate
  • Aerosol-cloud interactions
  • Convective initiation and enhancement, especially in mountainous areas
  • Water cycle, water vapour measurement and monitoring (incl. field campaign)
  • Atmospheric electricity

I do not teach this year.

In 2015-2016, I taught the B1 tutorials "Fluids, Flows and Complexity" and I advised a Master student for his MPhys project (2015-2016).
During my PhD, I taught in various topics and supervised Master students.

Previous teaching experiences

I co-supervised two Master students in Spring 2011, for their 4th year research internships.
I taught at the Blaise Pascal University, Clermont-Ferrand, France in the following topics (2009-2012) :

  • Introduction to Quantum Mechanics (2nd year)
  • Labs in Fluid Dynamics and Vibrations (3rd year)
  • Labs in Thermodynamics (1st year)
  • First year projects in Optics
