Now this will affect a vast area of atmosphere, because the air moving over that sea surface tends to take up the characteristics and if the temperature's higher on the sea surface than normal, the air becomes warmer than normal, and this sets up all sorts of reactions, it will probably produce a lot more clouds, for instance, and erm this in turn will cut off the sun's rays from that area of atmosphere, and this will have an effect on the whole erm heat engine of the atmosphere as we know it so erm we're now studying how far afield this is affecting the weather.
