NCAS Climate Modelling Summer School

Shammi Akhter – s.akhter@pgr.reading.ac.uk

The Virtual Climate Modelling Summer School covers the fundamental principles of climate modelling. The school is run for 2 weeks in the September of each year by the leading researchers from the National Centre for Atmospheric Science (NCAS) and from the Department of Meteorology at the University of Reading. I attended the school mainly because I have recently started using climate models in the second aspect of my research work and also because one of my supervisors recommended this to me.

What happened during the first week?

In the first week, lecturers introduced us to numerical methods used in climate models and we had a practical assignment implementing a chosen numerical method of our own in Python. We mostly worked individually on our projects that week. There were also lectures on convection parameterisation and statistical analysis for climate models.

What happened during the second week?

In week two, with the assistance of NCAS and university scientists, we analysed climate model outputs. I personally was involved in the Flat Earth experiment- in which we tested the effect of changing surface elevation for terrain such as mountains, high plateaus on the climate. In this experiment, the perturbation is imposed by reducing the elevation of mountains to sea level. There were eight people in our team. As you may know, we PhD students have the occasional opportunity to do research collaboratively with other students in Reading Meteorology and encourage our teammates. For this reason, it felt very nice to me to work as the part of a research group. I was amazed by how we had been able to produce a small good piece of scientific work just within a matter of days due to our team effort. In Figure 1, I have presented a small part of our work which is the global energy budget comparison between a control experiment and the flat earth experiment (where the elevation of the mountains has been reduced to sea level). Along with our practical, we also attended some lectures on the ocean dynamics and physics, water in the climate system and land-atmosphere coupling and surface energy balance during this week.

How was it like to socialize with people virtually?

We used the Gather.town during the lunchtime and after work to socialize. I was a bit surprised though that I was the only student joining the Gather.town and as a result I always had to hang out (virtually) with NCAS and university scientists all the time. I rather consider it a blessing for me as there was no competition to introduce myself to the professionals. I even received a kind offer from one of our professors to assist him as a teaching assistant in his course in the department.

Concluding Remarks

I learnt about some of the basic concepts of climate modelling and I hope to use these things in my research someday. It was also very refreshing to talk to and work with other students as well as the scientists. While working in a group in week 2, I once again realized there are so many things we can accomplish if we work together and encourage each other.
