Day two of EGU 2019 and as always it was a busy day. My program started today with a session on climate prediction. It was interesting to see different approaches to similar problems. Especially when you see in successive talks similar physical mechanisms described from different perspective, but explained completely differently. A chat between some authors would then certainly bring solutions to all groups, but I am sure some will not even have recognised the similarities.
The second session covered the North Atlantic. Like so many sessions here in Vienna this year the room where more than packed. The talks covered many different aspects, mainly on the thermodynamics. I left half-way, as I wanted to see some posters, which were mainly on statistics.
After lunch I enjoyed the medal lecture by Shaun Lovejoy, who gave an interesting overview of the different scaling mechanisms in the atmosphere and the competition between random and deterministic approaches. The rest of the day was again visiting posters, trying to make my way into sessions (and failing) and finally sitting in the back of a statistics session to relax a bit.
Today I heard from several people that they got annoyed from the overfull rooms. You hear this complain every year at EGU, but it seems to get louder at the 2019 edition. Or maybe, the sessions I visit (and those of the people I talk to) just got a bit more popular this year compared to the years before.
The second day of the conference was a quiet day for me, as no must see sessions were scheduled for me today. It started again with the North Atlantic session, which this time focussed more on the oscillations, like NAO. Afterwards, I visited a medal lecture on SAR. This topic is quite far away from my daily work, but such conferences are always a chance to see things you are usually not confronted with. Important for me was the statement that in times in which data can be generated in huge numbers, data management gets more and more important. Big data requires new ideas on workflows, might have to include cloud services and poses new questions on data availability.
After lunch I visited a palaeo session on the common era, which also addressed in many points the long-term variabilities of our climate system. In a last session another medal lecture was scheduled and again the southern ocean was the topic. This time it was the circular current and a good overview on the methods used to understand this important part of the global circulation was illustrated in this talk. A good thing about medal lectures is that you can see in a compact way a whole topic. Even when you now bits and pieces about it, it helps to get deeper into it to by getting it introduced by a real expert of the research field. The final stage of the day was then the traditional poster session. Tomorrow will be half time, and it will start the busy part of this week for me.
Having studied meteorology and doing therein statistics lead me always back to sessions, which are not directly connected to my current research focus. Like today, where I started with statistical methods applied on precipitation data. It was in fact a very diverse session, since precipitation data, due to their properties, are quite complicate to handle. Afterwards, I spend my time in a session about ensemble methods, which mainly focused on supermodels. Therein within a multi model ensemble each model is not calculated independently but the models are allowed to communicate with each other. This seems to be an intresting approach, even if there is to proof that the result is really benefitial over indepently run models on a large scale. Nevertheless, the first results looked quite promissing.
The whole day was dominated by the large sessions on the current IPCC AR and so I took a look into one of their sessions in the early afternoons. Afterwards, it was time for the great medal lecture by Olivier Talagrand. He got quite quickly through his work of his own and his collaborateurs, which was nice to see. All the different data assimilation techniques in one hour was interesting and remembered me of a lot of lectures during my studies. A worthy medal recipent. At the end stand the traditional poster session.
In general I like the medal lectures, since they really allow to cover a whole theme in a little bit more detail and give a good overview over a topic (which depends of course on the abbility of the presenter). The traditional 12 minute slots can be sometimes quite tiring and so it is good to have some alternatives on the menu.
