Question: What impact does La Nina have on the monsoon season in Africa north of the equator?  What about El Nino or ENSO-neutral conditions?

I know that Mr. Rosecrans explained that the West African monsoon is forecast to be above average this season, but I'm curious to know if there is a relationship between ENSO and monsoonal activity there and elsewhere in northern Africa.

Thank you for reading this, and I look forward to hearing from you.
