"Role Model" is probably not the most accurate term, it's kind of nuanced and variable. Raise my kid role model? probably not, because most of his followers do not really know him on a personal level, his personal ethics or morals. I think he fits into the category of influencing the love of severe weather and chasing-type role model. He certainly influences a lot of people (there may be questions to the degree of positive or negative influence based on his methods), but I think a lot of that will be left up to the individuals themselves. Do they carbon copy themselves? or just modify their interests and decide, I'm gonna be a meteorologist! that's a positive thing, and if someone decides to pursue being a scientist by watching him, I think it would be safe to say, positive influence, but you're not modeling.
