http://weather.unisys.com/archive/sst/sst_anom-110220.gif Lots to talk about on the global sea surface temperature anomoly front. Indian Ocean.. The level of cold anomolies are quite striking and is likely to continue to persist for the next 12 months. This is because with the current westerly phase of the QBO, a lot of Saharan dust and generally dry air is going to inhibit moisture with an area of high pressure in the region. As the +QBO turns easterly over the summer/Autumn, we are likely to see more cold anomolies from the west based La Nina cool waters further. It will be interesting to see the effect of the lack of monsoonal rainfall on the Atlantic Hurricane season with less waves leading Africa. Pacific Ocean.. For the most part we still see the pattern which has been dominant all winter. A split Pacific Jet Stream with limited Tropical Convection (La Nina leads to cooler air which is dryer), and a dominant ridge south of Alaska. This is likely to remain the case for the next month or two with a likelyhood of warm air being pumped into the Arctic leading to bouts of -AO conditions as we enter April, most likely the final warming. Could be quite a thermal gradiant once we see the ice melt in early summer if the tropical conditions persist. Atlantic Ocean.. Currently we have a pretty clear signal for high pressure in the mid-Atlantic and low pressure into Scandinavia which would normally favour colder weather for the UK. In the tropical Atlantic, there is a more mixed story with the +QBO leading to warm anomolies and much more shower activity as the season progresses, which obviously favours high pressure at mid-lattitudes. I would suggest that the coming hurricane season will see a lot of those short lived storms that develop in the western Carribean and head north east. Conclusion.. Over the Pole - Likely to see a generally -AO pattern caused by a weak Pacific Jet Stream and strong Siberian High, however this will mean that whatever Polar Votrex remains is likely to be in the vicinity of Greenland, so the best the UK can hope for is the Vortex to back west over Canada, or move east towards Scandinavia. Tropics - With a strong signal for weak Pacific convection, we are likely to see the tropical Atlantic recording +OLR anomolies with the responce being a build of pressure to the north east over Russia. Mid-Lattitude - Strong signal for a mid-attitude high likely to develop over or to the east of the UK, though it may pull back westward at times.
