Sc praecipitatio
/ 0 Comments / in Low Levels, StratocumulusFormation of stratocumulus opacus clouds producing moderate rainfall at the time hence the change in sub-species to praecipitatio. At first look, to the casual observer, it seems like a boring dull day as a result of low pressure system. However, from space the overall comma-shaped clouds are nothing short of dramatic. As photographed, these clouds are appearing as thick gray blanket covering the whole sky because the layers are not visible as such clouds could be relatively thick. As per second thumbnail, showing the humidity and surface wind profile and in agreement with literature, these clouds have clearly formed due to difference in air temperature which in the surface pressure chart on the third thumbnail it was indicated as an occluded front wrapped well away from the mature Wintry low pressure system over Algeria. In fact, the impressive comma-shaped cloud system in the visible satellite image of the fourth thumbnail consisted mainly from stratocumulus and cumulonimbus clouds being generated by its wrapped up frontal systems. The first thumbnail show the typical weather sounding of the occluded part of a mature mid-latitude cyclone clearly indicating that the photographed clouds were below 2.4km hence consisting primarily of water droplets above freezing despite being the Winter season.
