The #fluiddynamics of a #forestfire are complex and strongly interact with those of the background atmosphere. This animation shows a smoke plume of a fire with a surface source of 10,000 W/m2 embedded in a daytime convective boundary layer. Simulation with #MicroHH #cfd Wageningen U&R.

Deep convection starting from a warm bubble turning and splitting into a left and right moving rotating updraft. Simulation of the famous Weisman Klemp case with #microhh. #cfd #fluiddynamics #wxtwitter

eScience Center RSE Peter Kalverla worked with Imme Benedict, Chris Weijenborg & Ruud van der Ent, a team from Wageningen U&R and TU Delft on moisture tracking software during our Small Scale Initiative. What is moisture tracking & what happened to the software? ⬇️ blog.esciencecenter.nl/cracking-the-m…

By combining model development and observations from the NWO Nieuws #SLOCS project and the Ruisdael Observatory, we created a cloud-resolving simulation with #MicroHH of The Netherlands with realistic boundary conditions derived from ECMWF ERA5. Movie by Bart van Stratum. Wageningen U&R.

Very intense extratropical cyclone predicted for tomorrow and Thursday night for Northern Norway. Interesting to see how it develops further, but the latest GFS run of 6 UTC predicts a minimum pressure of 937 hPa! meteologix.com/nl/model-chart…

PhD position available in our group! - You will estimate global fire emissions, on short and long timescales - And you will investigate which fires lead to tree mortality and which not Join us and work in an international team, see calipsovesri.org wur.nl/nl/vacature/ph…

850 hPa is particularly unhappy about the way of weather in Europe today :D

This workshop aims to assemble the diverse moisture tracking community to address and quantify uncertainty associated with moisture tracking models. bit.ly/4az3WPv Imme Benedict Chris Weijenborg Jessica Keune Gerbrand Koren

Today I will cycle with colleagues the #climateclassic from De Bilt to Groningen to raise awareness for climate classic. We will bike along the future imaginary coast line.

#Cycling4Climate 🚲🌊 | We are proud of the team of WUR scientists that demonstrated their commitment to climate action today! They cycled or ran along the 'future' coastline of The Netherlands, if climate change is not altered. Let’s show them some support!

Discussion open for comments on EGUsphere: Moisture transport axes: a unifying definition for monsoon air streams, atmospheric rivers, and warm moist intrusions doi.org/10.5194/egusph…

A big update to ARCO-ERA5 landed this week -- we now have a copy of ERA5 on native vertical levels with regular 0.25° horizontal resolution. This ~6 PB dataset is freely available as part of Google's public datasets program: github.com/google-researc…

The tail-end storm in the small system over N France is now clearly supercellar, with a beautiful hook. Damaging wind risk clearly continues.

One of the nicest conference locations I have been to. If you happen to be at #EMS2024, I will present on (a climatology of) cyclone clustering at 10:00 in the Chapel room.
