I've noticed for a few weeks the cold SST anomaly hugging the east coast of the USA (-2 ~ -2.5°c) together with the warm strip to it's south (+2°c), quite a gradient in SST's. I was wondering what effect this may have on the Atlantic weather systems. We still have the cold anomaly to the south of NFL, which should promote blocking at some stage down stream, but my gut feeling is that SST gradient will produce some quite intense depression that side of the Atlantic which may have a knock on effect of pushing the Azores High towards Iceland and maybe linking up. This would also fit with what Will mentioned about blocking at 30° Lat. Obviously I only look at this from a layman's perspective and have no technical credentials to back up my thoughts, however, I'm sure there a few others who may like to pass comment on their experience in this subject. -- Keith (Southend) http://www.southendweather.net e-mail: kreh at southendweather dot net |

I've always been a bit suspicious of that site. It often shows quite large negative anomalies not reflected elsewhere (http://lwf.ncdc.noaa.gov/img/climate...t.20061108.gif for example) and some fairly wild fluctuations. There have been persistent offshore winds in that area, which in fact is fairly normal, and does cause upwelling of cold water near the coast. More interesting for early next week is http://www.fnmoc.navy.mil/CGI/ww3_lo...rod=sig_wav_ht Graham Penzance |
