TL;DR
Ring current, azimuthal drift and typical particles life expectancy
I read that "the azimuthal drift is compromized because the typical life expectancy of ring current particles is only hours to days and thus of the same order of magnitude as the drift period". But, if it is so, why relevant current exist? How could we armonize the fact that the azimuthal drift is "compromized" and there a current that we have to consider, at least for its geophysical effect?

Please give us the reference to that. And you are asking about planetary magnetic field phenomena, right?
