For
those of us who live in the mountains, there's a variation on the
weather jokes. Don't like your weather? Go up or down a thousand
feet.
On
a quick road trip up I-5 to Seattle last week, I noticed that the snow on
Mt. Shasta came down to approximately 7000 feet of elevation.

Farther
north, I noticed that the snow on Mt. Hood came down to approximately
6000 feet.

We
expect this, of course, because it gets colder as you go north.
If
instead of going north, we'd gone south the same distance from Shasta
we could have been to Mt. Whitney. There, the lowest snow level would
have probably been around 8000 feet.
So
I wondered if there is a regular relationship between where you are
on a north/south basis and where you are on an elevation basis. After
a little research, I found out that there is, and it matches what I
noticed on the way to Seattle.
All
other things being equal, going 300 miles north changes your climate
approximately the same as going up 1000 feet in elevation.
Of
course, in most scenarios, all other things are not equal. If you go
farther from or closer to the Pacific Ocean, which is a huge modifier
of climate, that will change things as much or more than anything
else.
But
it is still an interesting comparison. Going 3000 miles north is like
going up 10,000 feet. So if I were to start in Sacramento, which is
near sea level, and go to the northernmost reaches of the Canadian
arctic (3000 miles), my temperature change in any given season would
be similar to going from Sacramento to the top of Heavenly ski resort
at 10,000 feet.
Useful
information?
Maybe
not. But fun!
