Storms from a while ago

Originally taken from a Eurolink blog post, that I wrote about this time last year,  I thought it was a timely reminder of that storm after the wind and rain of St. Judes' Storm.

It was twenty five years ago (and a week ago) that the South East of England was hit, by what some newspapers called, a hurricane or a very strong storm. Michael Fish MBE is a weather forecaster who has worked for the British Broadcasting Company (BBC) and is still known for a comment before a forecast he made on the 15th of October 1987:

"Earlier on today, apparently, a woman rang the BBC and said she heard there was a hurricane on the way... well, if you're watching, don't worry, there isn't!"

It was suggested that Michael Fish was referring to Hurricane Floyd in Florida, USA that had developed off the coast of Nicaragua on the 9th of October and had been referred to in the One O'Clock News bulletin. But to his credit, Mr. Fish did warn people of high winds for the UK and to "batten down the hatches", but the storm did turn out to be a lot stronger than predicted.

The BBC On This Day website for the 16th of October records that "at least 13 people are known to have died and many dozens have been injured, mostly by falling trees and buildings...winds hit 94 miles per hour (151 kilometres per hour) in the capital and over 110 miles per hour (177 kilometres per hour) in the Channel Islands" and "In the London Borough of Ealing alone, 600 calls came from people whose homes and cars had been struck by falling trees and debris."
 
 The BBC Science and Environment website for the 15th of October 2012 records that "an estimated 15 million trees were uprooted...with winds recorded at speeds in excess of 100 miles per hour (160 kilometres per hour or 86 knots)" and "at Toys Hill, the highest point in Kent, about 98% of the woodland...was lost".

It was suggested that this widespread devastation of woodlands was going to be disastrous, but with time it has been shown that the storm helped increase the woodland biota. Dr. Keith Kirby (of Natural England), a co-author on the Great Storm's ecological impact on woodlands (an interesting pdf on climate and woodland ecology can be found here) reported that the lack of woodland exploitation after the Second World War and decreased coppicing had led to the woodland canopy closing over and reducing the low-level biodiversity. The storm opened up the canopy and led to an increase in bluebell and primrose density as well as a temporary increase in the fritillary (a woodland butterfly)  population

Dr. Peter Buckley, the other co-author with Dr. Keith Kirby, found that the effects post storm changed the past monoculture of the woodlands. The tightly packed tall trees had shallow roots that led to them being easily ripped out, whereas as coppiced trees tend to be kept shorter and lead to less trees being damaged by the stronger winds. A lot of the woods regenerated naturally with pioneer species and since there were struggling with nature, there was less need for artificial management.

What are your memories of the Great Storm in 1987? Please add your comments.
