A Note on the Equinox.

Today is the vernal equinox (well, yesterday by thirty nine minutes to be precise) up here on the top side of the planet. That means it’s officially spring however you define it. So, here’s the weather forecast:

We’re going to get sub-zero temperatures for the next five nights at least. Friday and Saturday are pencilled in for snow. The temperature won’t rise above freezing even during the day on Friday, Saturday and Sunday (and maybe beyond.) Oh, and there’ll be a strong east wind blowing.

Some spring.

The spring is sprung, the grass is ris
I wonder where the mellow is.

Here’s something interesting, though. It occurred to me tonight that between the northern vernal equinox and the northern summer solstice, those places that lie between the equator and the Tropic of Cancer must get south-pointing shadows, and any rooms that have north facing windows will get sunlight at noon. And, of course, the converse is true of the southern hemisphere. Isn’t that weird? I never realised it before.
