You're providing leaves. I'm sorry but an official source from Marvel does not get pushed aside for a background detail like weather which has already proven to be something that is, as you put it, fallible. You're right a book may not always be 100% correct but neither do on screen details always, people are fallible and people are behind both the book and the details seen in a movie. Until such a time as the book, which is the most recent source on the matter, gets retconed by a correction or future release the book is more correct
