i cannot quote you the source but a micro-burst researcher once explained it to me as being due to the stronger upper level winds in the mid latitudes adding energy to the cell and enhancing the circulation speeds of updrafts and downdrafts, This was the so called escalator effect. Thus the resultant turbulence would likely be more severe.

This seemed a credible explanation. But as I stressed, I cannot point to any academic papers which explicitly state that this is the case.

Happy to be corrected.
