There are some similarities between Geoff Sharp's approach and Astromet's........ The word of the day Bary is epitrochoid You see Bary with you and Epitrochoid all sorts of chaotic effects can occur that an old cyclist like Milankovic really does not appreciate. What if that nice round orbit in the diagram was actually around you Bary as the (pardon the expression) as the center of mass of the Solar System? And so it was no long nice and round but meandering following you Bary....

Actually it isn't a mystery. There is more than 9ne cycle of these insects.

Adapt 2030 has a vid about how the changing uv output of the sun is playing havoc with animals....

Here is a nullschool view from May 18 that shows four distinct north-south loops across N America and Europe extending at least 20 degrees of latitude down to 30 North. In the west is Valerie beginning her plunge. In the east is the same general loop reaching NE Africa that has been in place most of the winter. I need an automated screen grabber routine as paging back in time is time consumptive. I don't remember these patterns for late Spring before. Someone show me how these are 'normal'. Scan forward 3 days Acid and there is your Scandanavian - Greenland high pressure ridge with lows coming across the bottom. earth.nullschool.net/#2017/05/18/1200Z/wind/isobaric/500hPa/orthographic=-31.09,58.14,353/loc=-30.885,21.917

Something is causing the atmosphere to behave strangely. And similarly the ocean currents seem to be in a non-standard mode. Or just as likely the patterns we have been aware of in the last decades may be the non-standard ones.

Or just as likely the patterns we have been aware of in the last decades may be the non-standard ones. Changes In Atmospheric Circulation from May, 2016 to May, 2017 - 10 hPA 500 hPA Two points do not explain a pattern ... but ... big changes in 10 hPA flow between 5/10/2016, where easterly flow occupies a 20-25 degree band north of equator and is bounded at 30 N by the standard Azores high, which, if you toggle forward by month moves westward into N America and re-emerges westward from Africa. earth.nullschool.net/#2016/05/10/2100Z/wind/isobaric/10hPa/orthographic=-46.73,26.53,353/loc=-49.147,-25.551 At 500 hPA, north-south circulation loops are confined north of 40N in a regular west-east pattern. earth.nullschool.net/#2016/05/10/2100Z/wind/isobaric/500hPa/orthographic=-46.73,26.53,353/loc=-49.147,-25.551 Fast forward to 5/10/2017 and easterly 10 hPA flow is wider, from 20S to nearly 30N, ... high pressure zone is still in same general location. earth.nullschool.net/#2017/05/10/1500Z/wind/isobaric/10hPa/orthographic=-46.73,26.53,353/loc=-49.147,-25.551 At 250 and 500 hPA loops are broader and further south. Move forward to 5/18/2017 and you get the dramatic loops recorded in the first post. earth.nullschool.net/#2017/05/10/1500Z/wind/isobaric/250hPa/orthographic=-46.73,26.53,353/loc=-49.147,-25.551
