In reply to James Edwards:
97/98 was a very strong El Nino and was also the worst Scottish season I can remember, however 2009/10 was a moderately strong El Nino and the conditions were excellent for months on end, so hopefully El Nino develops a little less strongly than forecast as a very strong El Nino seems to produce a mild winter over here around 75% of the time.
That said, there is also currently a large cold pool of water in the mid atlantic and relatively warmer water in the Arctic. This reduces the temperature gradient in the North Atlantic thus promoting less storm development and potentially leading to more high pressure over the north Atlantic.....
