Hurricanes and NAO
Its half term this week so I have not been pondering my future career as a teacher. This week I have been mainly thinking about skiing and how much snow there will be in Europe.
So I know that most weather forecasters are predicting a negative NAO (northern Atlantic Oscilliation) which is associated with lots of lovely snow in Europe. However I have noticed that we should in theory be about to enter a negative phase of NAO usually about a decade where most years its a negative phase NAO, with the occassional postive phase NAO. It has also occured to me that the hurricane phase is changing, so I looked into it and what do you know the decades that have the most hurricanes also have Negative phase NAO's. When you do a bit os Stats on the data if 2+ major (cataogory3+) hurricanes make landfall in the USA then it is 3 times more likely to be a Negative NAO. Just wondering whether the amount of hurricanes and the strength of the hurricanes might correlate with the strength of the Negative NAO, and if so does that mean that a negative NAO caused more hurricanes or is it just co-incidence.
Anyway I am off to look at the years which had the strongest negative NAO and whether they are also the years that have the most hurricanes recorded. You can take the scientist out of the lab, but they are still stupid enough to try and do statistics and any data available.
Forgive me if this is already known by all of you and a recognised phenomenon but it has only just occurred to me.
