So some may be wonder is the NAO,AO negative or not this week and beyond,well every sunday i will be doing a check in on the status of these things,so lets begin.
SO it looks like the NAO is becoming slightly neutral or staying slightly negative and at this time of year this is what you want from the nao because later it will more likely have a trend to go downward after the in late Autumn.
It seems like the AO is turning more to the slightly negative side of the chart,the AO is always less consistent so it will have its ups and downs as you can see by the chart.
The PNA is looking to stay positive which is good for the winter time.
