  1. I come from the Center for Weather Forecasting and Climate Studies of the National Institute of Space Research CPTEC / INPE of Brazil.

    I work in the area of continental surface processes, and I am public officials of CPTEC

    All topics are new and interesting to me. However, the main motivation is to understand how the new atmospheric models are constructed.

  2. Hi Paulo and everyone, welcome to the course. I am Michail, I work in the Earth System Modelling section at ECMWF and I am team leader of the Numerical Methods group. I will be giving two lectures, one in Semi-Lagrangian semi-implicit time stepping and one in other more general time stepping methods used by weather and climate models.  There will be plenty of material in the course from fundamental algorithms to more advanced topics to help you understand how the dynamical cores of atmospheric models are constructed and work. Looking forward to meet you all!

  3. Hi everyone,
    I am working here at ECMWF on reduced numerical precision and machine learning to improve weather and climate models and evaluate the quality of simulations at very high horizontal resolution. I am looking forward to talk to you next week!

  4. Hello Everyone,

    I'm Paulo Medeiros, scientific developer in the Meteorological Research group at the Swedish Meteorological and Hydrological Institute (SMHI).

    Having previously worked in the field of Computational Condensed Matter Physics (roughly describing, quantum mechanics applied to the study of matter), I have a somewhat unusual background within my group here at SMHI – and perhaps also among the participants in this course. Nonetheless, despite the difference on the typical grid sizes (~1E14), the basic mathematical and computational methods employed are not so different (for instance, spectral methods are also widely used in condensed matter physics since we deal a lot with periodic systems).

    My aim with the course is to acquire a better understanding of the various numerical methods used in the specific context of earth system modelling. I am looking forward to meeting you all!

  5. Greetings to All,

    I am Piotr Smolarkiewicz, and I am Centre’s consultant on numerical methods and development of dynamical cores for of all-scale global weather forecasting. My lectures will address all-scale simulation of atmospheric flows. In particular, I will talk about choices of governing equations, their semi-implicit integrations, and elliptic solvers.

  6. Hello all,

    My name is Alan Hally and I'm a meteorologist at Met Éireann, the Irish Meteorological Service.

    My background is in numerical weather prediction and specifically the representation of physical process uncertainty using ensemble prediction systems.
    At Met Éireann I work in the NWP team and am responsible for EPS development and maintenance as well as NWP related applications.

    I look forward to meeting you all!

  7. Hello Everyone,

    My name is Opeyemi Salau. I am a lecturer from Ekiti State University, Nigeria. I studied climate modelling and I have strong interest in climate variability and the impacts on the society. For instance, I am working on the distribution of malaria diseases in some parts of Nigeria. Thus, I wish to improve my modelling skill during the training course and also to know if malaria cases could be accurately simulated for better monitoring and control.

    I am also looking forward to meet you all.

  8. Hello Everyone,

    My name is Ivar Ansper. I work in the Estonian Environmental Agency as specialist of nwp for 9 months. Mainly I work with HARMONIE model for operational purposes. I would like to get better knowledges of numerical methods for earth system modelling.

    See you next week,


  9. Hi all,

    I am Willem Deconinck, working at ECMWF since 2012 on numerical methods and scalability thereof. I will present a lecture on higher order discontinuous methods and be guiding some practicals on advection.

    I'm looking forward to get to know you soon!

  10. Hi everyone,

    I am a PhD-Student at Météo-France. I am working on implicit grid point solvers in the french LAM AROME as an alternative to the current spectral solver. I would like to have a general introduction in advanced numerical methods for solving non-hydrostatic dynamic equations with a focus in elliptic solvers (iterative solvers, preconditioning techniques, etc) and their suitability in massively parallel computer architectures.

    See you next week,


  11. Hi all,

    I am working with ensembles and statistical post-processing for the Spanish Weather Service (AEMET). I am interested in learning more about meteorological models. Looking forward to meeting you all.


  12. Hello everyone,

    My name is Lorenzo Zampieri. I am a PhD student at the Alfred Wegener Institute for Polar and Marine Research (AWI) in Bremerhaven (Germany).

    My research focusses on sea ice modelling and in particular on the development of new parameterization for the sea ice thermodynamics. Because of the strong linkages between sea ice evolution and atmospheric state, I am looking forward to learn more about atmospheric modelling and numerical methods during the training course.  

    See you all next week!

  13. Hello,

    I am Lorenzo Silvestri,  PhD student at the University of Perugia, Italy.  My background is in computational fluid dynamic applied to turbulence and small scale phenomena, but now my research project is about meteorological data validation, analysis and downscaling. I usually work with data coming from large-scale models (mainly ERA5 reanalysis) and since I am new to this field I would like to learn how these models work and how they are solved! Moreover I really like numerical analysis!

    See you soon!

  14. Hi everyone,

    I have been working for 2.5 years as a scientist at ECMWF on the ESCAPE projects. My main focus is the spectral transform method and code optimisation. I will tell you more about this in my lectures and exercises during the training course!

    See you next week!

  15. Hello everyone,

    I am a PhD student at the Max-Planck Institute for Meteorology in Hamburg, Germany. There, in the ocean department, I am a member of the group applied mathematics and numerical physics. I am working on a new (split-explicit) time-stepping scheme for the ocean component of the ICON-ESM. This is a very specialized topic and so my aim with this course is to get a broader knowledge in all kinds of numerical methods.

    I am looking forward to meeting you all!

  16. Hello everyone,

    I am a PhD student at the University of Trento (Italy) and I am working on turbulence parameterizations in the WRF model, in particular I would like to improve them for complex terrain studies. I am at first year and I am very happy to follow now this course, which will give me a strong numerical background that will be very useful for my PhD.

    See you tomorrow !

  17. Hi,

    I'm Inna and I joined numerical aspects group just over 6 months ago. I work on ECMWF's operational dynamical core, and in particular, on consistent vertical to horizontal resolution aspect ratio. My other interests lie in improving the representation of the stratosphere with the aim to improve weather prediction in the troposphere. This week I will tell you a bit about resolution, validity of hydrostatic approximation, and, resolved convection.

    Looking forward to meeting you soon!

  18. Greetings to Everyone,

    I am Gabriella and working in the OpenIFS team of ECMWF. I will demonstrate for you how to set and run a real global model. For this purpose we will use OpenIFS which is the version of the ECMWF IFS model available for research and education.

    See you soon!

  19. Hi,
    I received a note today that was written during the course with a question about the impact of reduced precision on the phase space. There was no name on it but if you read this:
    Yes, a reduction in precision can have an influence on the phase space. It can reduce the area of the space that is filled by the model (this is what you do not want) but it can also introduce noise and increase the area that can be reached (similar to the use of stochastic parametrisation schemes to improve climate simulations). However, it is difficult to optimise the phase space with precision (other than checking that important model features are still present as precision is reduced). Please let me know if you want to know more about this.

    1. Thank you for your answer!

      It was just a curiosity from your lecture.

      Have a good afternoon,


  20. Just to let you know that Andreas has be working on the spectral transform methods practical.

    Hope you are all well!
