The fourth day of the IMSC 2019 was the day when the heat wave finally hit Toulouse with full force. Around 40 deg C was what the temperature measurements told us and it felt a bit overwhelming. The morning started again with plenary sessions and talks about uncertainty separation and down-scaling. Afterwards followed the poster session in a tent outside, and it got warmer and warmer over time as the wind was not as strong as in the last days.
After lunch the parallel sessions for the day started and I chose the one on forecast evaluation. The first part was reserved for the development of new verification procedures and I had my own talk in this section. It went alright, I presented two new skill scores basing on the EMD and demonstrated it at different seasonal prediction applications. The second half of the session was on the application of verification procedures and showed many different fields.
With the end of the talks it was time for the social events. The choice was either a wine tasting on a ship or a walking tour through town. I chose the latter one and it was a challenge to always find shade to get not too warm in the sunshine. Tomorrow will be the last day and the weather will still be warm enough to be a challenge.
