How can the Arctic get flushed with warmer latitude water every 18 years or so? This appears to have happened recently – so what mechanism could be at work?
According to EM Smith it is down to lunar effects, or tides – go to http://chiefio.wordpress.com/2014/02/16/tides-vectors-scalars-arctic-flu… … and that 18 year cycle gets, in turn, accelerated by luni-solar factors, every once in a while, producing bigger flushing out of the Arctic. The result is a range of tides from near zero to 50 feet – which is the point people get worried by sea floods.
Tides change with axial tilt alignment – see http://stevekluge.com/geoscience/images/tides.html and http://faculty.ifmo.ru/butikov/Oceanic_Tides.pdf … and what this all seems to mean, according to the authors, and the Chiefio, is there is more to the weather than climate science models can currently cope with – yet alone embrace. Lots and lots of factors are just omitted from the models. The excuse is that they are too small and insignificant – but tides can be big things. Flushing out the Arctic periodically with the redistribution of water from the tidal bulge as the Moon moves around the Earth, and both interact with the Sun, may not just be a factor in recent melting of sea ice, but the sea ice melt of the late 1930s (see http://stevengoddard.wordpress.com/2014/02/17/the-importance-of-getting-…)
