Its is sound...you need cold to snow.
I never denied Hadley cell expansion and global warming, but it can't rain above the latitude of Myrtle Beach from December to March without eliciting a 7 paragraph exercise in pedantic redundancy from you....which awkwardly concludes with a line or two of lament about how no woman wants to look at you, and the one that did, no longer wants to.
It's always rained in the mid latitudes during winter....its not always a sign of cannibalistic Hadley Cells eating the world.
