THUNDERSTORM 0002

 

Date: 07-06-1996    Time: 20:45 BST
Location:
Macclesfield, Cheshire UK
Storm Stage: Mature (multiple cells)
Path / Movement:
Overhead / Northwards


T0002 consisted of several large active cells pulsating northwards along a thundery cold front. They occurred at night-time making them more spectacular and had a total duration of about 3 hours. I a
udio-taped the thunder and captured a few good ones including a couple of loud crashing thunders. The storms cleared the area at about midnight. Obviously I only audio-taped the peak of the activity when it got close, however after three hours of watching I then got bored of the distant discharges and went to bed. It was an excellent storm though which would have been a good one to film.

Looking at the Dundee satellite quick-looks the storms generated were a result of warm moist air being dragged up from the continent being lifted by an approaching secondary cold front wave from the west. Looking at the 02:15 IR image it is clear that there were large amounts of convective activity running in a line up the country, and possibly also in the North Sea. The difference in the IR signal can be seen behind and ahead of the front showing a strong temperature gradient. By this time a new "cut-off low" appears to have formed in the Bay of Biscay along the waving cold-front. This waving line of slow-moving but intense convection is the likely cause of such a succession of storms in the north-west region on this night.
