How Does ozone deplete?

Dear Reader,
It has been long time since I last wrote. Sorry, if you had been reading, for the delay.Today, instead of having a long talk on some serious environmental disorder, I rather want to ask you a question.And the question is: HOW DOES OZONE DEPLETE NATURALLY?
Now you might say that its a really silly question, or you might reason and blame the NO2 produced during lightning! But that is not the exact QUESTION!!!
I'd rather ask: If most(nearly all) of the climatic activities take place in the troposphere, and the Ozone layer is present in the stratosphere, how does the NO2, which is produced during lightning, combine with O3 to deplete it?
You might cerebrate that it might rise up into the Stratosphere and take up the following reaction:

2NO2 + O3 -> 2NO3 + [O]

which it does.but why not:

2NO2 + O2 -> 2NO3

when oxygen is readily available in the troposphere itself!
If you know the correct reason or have a good( by 'good' i mean sensible) reason, send it to me at machomono93@yahoo.com.
Thanks,
Abhishek
