Weather Bombs

Interesting weather conditions just up on the north coast, We have been watching pictures on TV from there and the west coast of Scotland, mainly places we have visited recently like Largs and also the coast of Antrim Portrush etc.

The winds have been over 100 mph at times and waves of 50ft have ben recorded. We however have got away very lightly. Today the winds were only gusting to 28-30 mph but were strangely gusting around the compass swinging through 360 degrees. The majority of the time wind speeds were in the force 2-3 bracket.

The conditions up North have been caused by a slow moving and very deep low that has been deepened even further by a dip in the jet stream (bit like a child's toy, the whip and spinning top for those old enough to remember one) The now fashionable term for a depression that is deepened by some other phenomena is a `Weather Bomb` in the case of the famous Fastnet storm it was a secondary low. In this case it is dry air from the stratosphere deepening the low pressure by a process known as explosive cyclogenesis. All pretty scary stuff.

And another storm due tomorrow, fingers crossed.
