Chuckle. I like that. Of course, the problem with Mordor was that it was a volcanic basin surrounded by high mountains that did not allow tropospheric interaction with oceanic weather systems originating in the Bay of Belfalas, but that's just details.
For grins, here's a radar image of Okmok Caldera in the Aleutians, which I've always considered the best Earth-equivalent of Mordor. The floor of Kilauea caldera looks more like Mordor, but it doesn't have mountain in the middle and a ring of mountains around it.
