I Was Wondering
What's the difference between Meteorological Winter and Astronomical Winter?
|These icy trees didn't wait for astronomical winter.|
After a little reading, I figured out that it's easy to explain meteorological winter. It's the coldest three months of the year--December, January, and February. However, astronomical winter is a little more complicated. The beginning of astronomical winter has to do with the with the tilt of the earth's axis and the earth's orbit around the sun. It is best explained by pictures or a simple video that you can see here, but basically it is when sun strikes the earth at a minimum angle. This is also known as Winter Solstice and this year will be on December 21. Astronomical winter continues until the Spring Equinox which will be March 20, 2014.
So now I know.
(Obviously, this discussion is for the Northern Hemisphere. I'm a little jealous of those of you who are starting summer right now Down Under.)
A Second Look
Here are some things I saw this week during a Second Look.
|Even though we have had plenty of days in the 20's, we have a few pansies still blooming.|
|However, many of the pansies look like this. Something has made a snack out of them.|
|Maybe it was these deer that enjoyed the pansies.|
|I think the groundhogs have begun their winter hibernation because I haven't seen any activity around this hole recently.|
|The leaves are all gone from the trees which makes it easier to see the birds in them. See the cardinal?|
