passive solar heating

January thaw

Jan. 25, 2014 A windy, mild and sweetly melancholic day with scudding clouds from the southwest. Snow and ice are melting without man-made stimulants. Once again I'm rather surprised and pleased by how the light is brighter in late January than even just a couple of weeks before, and by the power of  even the winter sun to quickly heat us in sheltered places.  Our unheated but glassed-in sleeping porch, which faces the south, gets up to 75 even when it's 15 outside. We use the space to heat the adjoining bedroom by day.

We New Englanders could do a lot more with passive solar heating.  It's not as if we're that far north; we're at the latitude of Portugal.

One nice thing about aging is that while the cold itself is harder to take, especially the windy chill of Northeast coastal cities, you're ever more aware of how fast time goes -- it will be spring very soon. And while it has seemed recently that we're living on Hudson's Bay, actually we're much closer to the Gulf Stream.

In New England, more than in most places, we have the weather to help mark off sections of our lives, as an aide-memoire, and that's handy. Now we have the predictable "January thaw,'' which, though this one will be very brief, reminds us that our weather won't  really be paralyzed by the likes of "polar vortexes'' or other such Weather Channel monsters. By the way, California is having record heat and drought. And Alaska has been pretty warm for, well, Alaska.

Scientists differ on why the rise in temperatures associated with the "January thaw' ' tends to happen in late January rather than in early February, which would seem to make more sense.  In any case, I'm more vulnerable to the sadness from lack of light than from the cold. And the light is moving in the right direction.

Something to look forward to

Jan. 7, 2014

Cold morning today but far from the "polar vortex'' catastrophe that  it's being made out to be by the news media because their denizens think that  nothing much else is going on. Of course, lots of stuff is going on but it bores those reporters and editors who haven't yet been laid off in the ferment caused by the triumph of mostly ''free'' information on the Internet. And maybe the public doesn't care all that much either.

Most importantly, "polar vortex'' sounds like a horror-movie monster. Very sexy. More vortexes to come because global warming is screwing up the jet stream? Too early to say with scientific assurance.

It's all rather typical of January, the coldest month. But  February is often the snowiest  because warm wet air begins to edge north again, setting up conflict with the cold air. Great for creating  Nor'easters! Arctic air and the Gulf Stream can be in explosive proximity.

As I walked the dog this morning I enjoyed the crunch of my feet on the thin layer of snow that had fallen overnight as the front swung through from Canada,  bringing a snow squall or two.  And the frozen  trees were creaking. Too cold to be slippery! The problem in the coastal Northeast is the wind. It can  make urban walking miserable. When I lived in the Upper Connecticut River Valley, the temperature could be much colder than in Boston, Providence, New York and Philadelphia but the comfort level much higher because there was much less wind and it was very, very dry. Sort of exhilarating  -- bright and almost antiseptically clean.

Meanwhile, along the lines of ever-more "nurturing'' of children by parents and schools (at the ones I attended we were often called by our last names and there wasn't much open concern for our feelings), is the practice of clothing our dogs for winter walks,  even outside of the Upper East Side of Manhattan. I must confess that my wife and I have adopted this habit. The dog, a rescue mutt from San Antonio (via "Alamo Rescue''), fought having a coat on at the start but has since accepted it -- especially when  it's windy.

My most physically painful memories of winter are in the streets of big cities with the northwest wind squeezing between the high buildings.

When it's really, really cold,  ice is  so sticky that you don't even worry about driving up and down steep snow-covered hills. A few times I had to drive my  drunken mother to a drying-up spa at a place called Beech Hill Farm, on top of a mountain in Dublin, N.H. -- the little town where Yankee magazine was, and is, put out and where Mark Twain spent some happy times. If it was the winter, I'd pray for very cold weather.  Around freezing was the most insidious,  with a thin layer of melting in the sun, then quick refreezing toward evening.

The dramatic freeze-thaw  cycles in New England  make skiing more, well, exciting here than on the dusty, dry "powder snow'' promoted by resorts in the Rockies. Skiing in the White and Green mountains is much more of a challenge to muscles and nerves than is skiing at, say, Taos.

Anyway, I long for late February, when sun-facing cars and rooms suddenly seem to start to warm up  much faster  as the sun gets stronger. Even on a very cold day last week, I found the stone on a southwest-facing wall remarkably warm. We really do need to do a lot more with passive solar heating.
