Spot the sea breeze!

Neat clouds from Bern, Switzerland. Lenticular (ish) and KH (ish).

Successful eclipse viewing with the Mark I Colander

Perfect day for some coaching

Finalising some figures of an idealised deep convective cloud top. Reassuring when simulations resemble observations!

Ice crystals are beautiful!

At this time of year, it’s hard not to go slightly blind when taking cool cloud photos…

We also looked at metrics that quantify mixing. We identified a three-stage mixing process, each with distinct characteristics. It turns out the most efficient mixing occurs in a thin layer at the top of the plume.

To understand turbulent transport and mixing, we use a phase space where the fluid buoyancy and tracer concentration are the coordinates.

It turns out the mixing is much clearer in this space and clarifies the mixing process between plume and environmental fluid.

Shelf cloud over the Centre for Mathematical Sciences in Cambridge earlier today

Hints of mammatus?

Curious diffuse Cirrus!

Started a cloudspotting log at cwp.io/log. Will post here as well in future. A few recent favourites...
