Happy Vernal Equinox!
Friday, March 19th, 2010Swollen swirling streams running off the snow pack, song birds flitting and singing, insects beginning to hatch from their nests, the first crocuses poking out of the cold dark soil… The rich smells of composting oak leaves, sweet maple sap and wet tree bark! Ahhhhhh… the renewal of the Earth, and all of it’s waking creatures pregnant with possibilities!
Those of us living farther north feel like we have more reasons to appreciate the arrival of the official beginning of spring more than those closer to the equator. After all, for many of us, our lined britches, “long johns” 24/7 socks, outdoor hats and gloves have become a way of life for months! We have noticed the sun rising earlier and setting later, and we rejoice that the light LOOKS different, even if the earth tones are still patched with snow.

If this is the midpoint between winter solstice and summer solstice, why are the daily high temperatures still close to freezing? And why are night time puddles still freezing up here near the 45th parallel? It all comes down to albedo. According to NOAA, ice, snow and water, reflect the sun’s energy back out to space. This reflectivity is called albedo. Snow cover in the north keeps our air colder for longer in the spring. Those of us who live here know that once the snow finally melts, and the good earth begins to absorb heat during the longer days of spring, things will warm up quickly.
We notice more signs of spring every day. There’s a northern oriole in the back yard now! Oh, that reminds me, I have some maple sugaring to do! Later!
