Saturday 18 April 2020 – Fractocumulus


Herne Bay, Kent.  Cool but air weather after rain this morning.  Some high altocumulus but underneath and much close to the sea are patches ragged cloud fragments formed by shallow convection currents and cool moist air flows over relatively warm sea and land surface.  So, cloud out at sea is fractocumulus.  Next photo, taken into the sun with a polarising filter, shows the lower more clearly.


Nothing much is changing in the synoptic situation.  Slow moving high pressure in west of Norway leaves remanants of fronts and trough lines.
