This fluid is #rheoscopic, easy to make at home using shaving cream.
Here's the recipe:

At the Nordita workshop. Getting some people across physical disciplines (theoretical, numerical, lab and field) to talk to each other. Some very interesting lectures. #oceanography #convection #turbulence

Any articles?
To me 👴 curtains should be folded on windowsill so all heat circulates in the room?
Any devices to enable this?
Looking for evidence, so not berated by aesthetic better half! ☹️

One component that is missing from the above analysis, and not isolated in most estimates of aerosol-induced #cooling, is #evaporative cooling due to aerosols.
Aerosols increase evaporative cooling through two pathways.
1. The radiative effect (global dimming) changes how energy is redistributed through evaporation versus #convection. Convection is reduced more, and there is net evaporative cooling.
This pathway is more important, accounting for 84% of response globally (81% for #tropics).

With colleagues from Argonne National Laboratory, we will be working on “Convection-Permitting Climate-Scale Simulations for Extreme Event Modeling".
The results from this work will provide a unique database for Climate Risk Estimates at Local Scales.
