THUNDERSTORM 0054
|
Date: 18-08-2004
When it got closer a strong and defined arcus cloud (or roll-cloud) was evident all the way along the west horizon. There was a constant background rumble of thunder caused by weak discharges taking place just behind the arcus cloud that were only visible as very faint flashes. I was expecting to see some C-Gs from under the arcus but throughout the entire storm I didn't witness one single strike of the like. As it got closer the arcus cloud demonstrated classic “Whales Mouth” formation dominating the skies and looked incredibly dramatic. The hidden low-amp lightning continued in between the roll-cloud and the rain curtain until finally giving way to a large smooth downdraft base in which large C-Cs started to spark all over the show with return strokes and new leaders. The C-Cs were still of low-amp nature but they looked good and were bright compared to T0053.
This was one of the most fully-documented storms I have filmed in terms of characteristics. The thunderheads were clearly visible and were mushroomed, giving away strong and defined updrafts. Then the dark arcus roll-cloud pushed in with the Whales Mouth formation, then a splash of C-C lightning within the core parts of the cell. Then to finish it off, the dormant thunderhead sat opposite the sunset. All it needed was a rainbow to put the icing on the cake!
