   Sorry Eli
   just seen your message- its up to you , but some discussion of the drought /solar or
   solar/lunar mixed forcing as far as the evidence goes would be good. This is a
   controversial topic and if true I do not think the mechanisms are known anyway. Hope this
   helps

     hi keith
     do i need to cover how these factors affect drought in my presentations on
     mechanisms or is it sufficient just to mention them;
     Hale solar magnetic cycle the lunar nodal tidal cycle  the Pacific Decadal
     Oscillation the North Atlantic Oscillation (NAO)
     thanks,
     elie.
