Re, ... do you think the fires in NSW are playing a role in this unusual cold front hitting the US?
Yes !! ... The updraft from all those fires in NSW sucks all that cold air from the Arctic ... and sends it all over the US of A !!What causes an updraft?Updraft and downdraft, in meteorology, upward-moving and downward-moving air currents, respectively, that are due to several causes. Local daytime heating of the ground causes surface air to become much warmer than the air above, and, because warmer air is less dense, it rises and is replaced by descending cooler air.
