Lifetime average

[RandomlyHuman]

Hello again dear Antoine,

I would like to consult you on something that is perhaps very basic, but I still can't quite understand it. I have been able to perform (examples) well the monitoring, but following also the recommendation you gave from this document from (Chelton et al, 2011). I also followed these questions, to see if maybe someone has asked the same question before and not to repeat it once again.

But I still don't understand how to determine the average lifetime of the eddies in the example, or how can I proceed to perform this calculation.

My question arises from this sentence 'These 36,000 eddies have an average lifetime of 32 weeks and their average propagation distance is 550 km.' (Chelton et al, 2011). and as it has similarity with one of the examples, I would like to know if there is a way to make this calculation.

I thank you in advance once again for all your valuable help.
