There is a popular assumption that if you move to higher latitudes (toward
poles) you can escape
heat, and that by moving to lower latitudes (toward
equator) you can escape
cold.The equation is simple. But is it real? If it was, then
most northerly capital, Reykjavík, would also be
coldest...at least until they establish a country on Antarctica. Yes, it appears that latitude is slacking off and failing to keep temperatures in line.
This was brought home to me when preparing for a radio interview in Dublin, Ireland. February had just roiled in and I was sitting back comfortably in my good old Ottawa, Canada weather, scraping icicles off my toes. I was giddy with excitement over our warm spell, which it was reaching a high of minus-5 (that's about 20-degrees American). I always ask questions
day before an interview, to learn a bit about my audience, so I asked
producer, "So what's
weather forecast in Dublin?" asked.
"Oh it's horrible," she told me. "People are bracing for a deep winter freeze that's supposed to hit tonight. It might even get as cold as minus-5!"
This blew me away, that
folks in Dublin would be worried about
thermometer dips as low as ours spikes high. After all, isn't Dublin about
same latitude as Ottawa?
Weather forecast from an atlas
I whipped out my trusty atlas. We live almost exactly on
45th parallel. If we lived exactly on it, we would have to share our bed with a cow and a dozen chickens across
road – that's how close we are.
I turned
pages to find Ireland. Could I have been mistaken? Is Dublin really quite south of us? No, it turns out that Dublin lies at
53rd parallel. Hey! They should be getting colder weather than us. That's not fair.
