Swirl ratio

Oct 20, 2014 - 8:52 PM - by Caleb Routt
So what exatly is swirl ratio? And what does it have to do with creating suction vorticies? I have thought about it and ive came to the conclution that all it means is how much horizontal circulation is vs the updraft of the thunderstorm

Looks like forecasters get to prove how good they are without totally integrated model data. Just saw NCEP issue a statement regarding the satellite data outage in reference to forecast accuracy.
