This is actually a tropical cyclone off Madagasgar …
Pretty nearly all tropical cyclones show up in the North Atlantyic. They are the extra large but not neccessarily dangerous systems that hover over the MidAtlantic Ridge for the duration.
And of course are followed up by a large magnitude set of quakes some 80 degrees away at their demise.
My problem is that I don't know where to get upper level layer details on archive. That and the fact I don't know how to interpret upper layer charts.
What I do know is that when the Low in the tropics meets the high it is connected to os that one is directly above or below the other, then the supertyphonn-hurrican esyndrome comes into effect.
A Low drags air from the sea surface up to the middle of the troposphere. And an anticyclone above it turns it into a "Bomb" a cyclone that can derop in pressure explosively . (That should be Implosively.)
A similar feature links flares with sunspots on the solar surface. (So much for nuclear reaction caused by gravity and magnetic storms. Ha!)
