I don’t think Blue Ayanami should be considered a reliable source, regardless of what information they have.
I know this might seem like a wild take, but Im a person who has edited wikipedia articles multiple times with sources that aren’t fake. Now im not accusing Blue Ayanami of being fake or anything, but theres always a chance that someone could edit newspaper articles and just state it there, not to mention news paper articles from newspaper archive (or newspapers.com) are locked behind paywalls.
It kind of just seems like everyone accepted it rather then doing there own research, this would make sense if Blue Ayanami was a meteorologist, but they aren’t, further research suggests they have a degree in psychology. Thomas P. Grazulis is considered a reliable source since he his a researcher and is a meteorologist.
But unlike Blue Ayanami, there’s multiple sources that document Thomas P. Grazulis, these two both alone aren’t official sources but one of them is more believable or acceptable since they have experience with weather. Tornado Archive is the only site that accepts Blue tornadoes rather then citing the true reliable sources (which are newspapers, or anything else for that matter.)
Now again, im not accusing Blue Ayanami of editing articles in their books, but I think its always better to be safe then sorry and trust other sources that are guaranteed to not be fake.
