The Delicate Pastel Colors of a Northern Adriatic Sea Dawn Make a Distant Supercell Seems Less Angry than It Is; Trieste Gulf, Muggia, FVG, Italia
05-august-2021: if it were not for the very distant thunderbolt (which fell on the Northern Veneto plain, over 150km linear from the shooting point!!!), the Anvil cloud (Cumulonimbus Capillatus Incus) with the arched edge, which is a high probability index for Supercell thunderstorm, would almost pass unnerved, thanks to the low contrast of the very first light of the day.
The Supercell is the potentially strongest thunderstorm system that the Planet can produce: tornadoes can develop from it (up to 512km/h, the most extreme one, on average on 180/270km/h of spiral rotary wind!), large hail and sudden gusts of linear descending winds (outflow into downdraft) up to 160km/h.
In hot summers Supercell thunderstorms are also quite frequent in Europe (in addition to sub-tropical areas and the US mid-west, from may to november...), especially in the Po Valley and in the Veneto-Friuli plain.
What stands out (top right) is the high-altitude arc cloud that can extend to cover tens and tens of square kilometers and it is (obviously) only visible from great distances (as in this case), but the thrust in height and then in amplitude it is given by that one at medium-low altitude ("Shelf Cloud", essentially the cloudy base of all the thunderstorm cell), rich in energy and very tormented which, always arc shaped (and non-linear as in "non-super" thunderstorms), precedes the precipitations, and is visible, however, only at a short distance from the storm focus.
The cloudy structure of the Supecell has a development, in slow motion, which is similar to that which occurs after the explosion of an atomic bomb.
All this from a pastel photo at dawn from the quiet Istrian promenade of "my Sea"!
