Euopean ETC activity from 1990 onwards
Transcript of keynote speech by Donald
Burfitt-Dons continued
There were a total of five in 1990, a very active year.
On 17th January that year ETC Daria crossed Northern Scotland on the
way to creating mayhem and destruction. Nearly 100 deaths and at least
4 billion dollars in insurance claims. Core pressure this time was even
lower at 949 mbs. Daria had a broad footprint and so caused significant
damage and loss of life.
And so it has continued.
But now, as we look at the last ten years the pattern
becomes even clearer. Ever more frequent extra tropical cyclones, and
deeper core pressures.
We’ve counted 18 making landfall on continental
Europe in the last ten years.
ETC Erwin in 8th January 2005 got everyone’s
attention.
A Cat One cyclone, his core pressure was 961 mb
s
with sustained wind speeds of 68 knots and a death toll of 17 souls
and a record insurance claim.
3 days later Scotland was hit by another ETC with a
core pressure of 944 mbs and superwinds of 116 kts equalling a full
Cat 3 Hurricane. If you refer again to your hand outs you will see that
at 944 mbs this ETC had just entered the tropical equivalent of a Category
4 hurricane.
Furthermore, we are now getting kind of typhoon twins,
that is, two storms one following another within a day or so. In all
my years of flying I never noticed this phenomenon, although I believe
that a similar chain did occur in1942, but still it’s very very
unusual. Continued Donald Burfitt-Dons
