Indian ocean dipole

Hi, apparently there is a neutral indian ocean dipole occurring in the Indian ocean this year. Does anyone know what this means regarding the trades , ie will they be stronger, lighter or has it little relevance? Plan is to sail from Darwin to South Africa, so interested in what effect the dipole has.

Cheers Dale.

Re: Indian ocean dipole

Hi Dale. I knew nothing about Indian Ocean Dipoles until I read your question. From limited reading positive and negative dipoles refer to temperature differentials between east and west Indian Ocean with the resulting climate changes. Wouldn't a neutral dipole mean there is no temperature differential and therefore a normal sailing weather?

Re: Indian ocean dipole

Hey Keith, that's what I figure but im not sure. Being the comfort sailor that I am Im hoping for a nice calm 15-20 behind the beam, the more cups of tea I can make a day the better..lol.

With no temperature differential, I would expect lighter, more variable winds. in the tropics.

Sailing to South Africa, however, you should be south of the IOD induced weather patterns for most of the trip.
