Mammatus clouds, Hastings, Nebraska

From Twitter today; working to track down more details.

A photo by John C. Olsen, taken in Hastings, Nebraska, perhaps on December 31, 2013:

Our boys liked clouds from the start.  A couple of our early cloud identification books featured mammatus clouds (guess where the name came from); and before each boy was 11, we had seen these clouds here in Texas, often in that treacherous time known as tornado season.

Beautiful clouds, yes, but often scary — well, until you read from the University of Illinois that they tend to follow nasty storms, not precede them.

Mammatus Cloudssagging pouch-like structuresMammatus are pouch-like cloud structures and a rare example of clouds in sinking air.

Sometimes very ominous in appearance, mammatus clouds are harmless and do not mean that a tornado is about to form; a commonly held misconception. In fact, mammatus are usually seen after the worst of a thunderstorm has passed.

As updrafts carry precipitation enriched air to the cloud top, upward momentum is lost and the air begins to spread out horizontally, becoming a part of the anvil cloud. Because of its high concentration of precipitation particles (ice crystals and water droplets), the saturated air is heavier than the surrounding air and sinks back towards the earth.

The temperature of the subsiding air increases as it descends. However, since heat energy is required to melt and evaporate the precipitation particles contained within the sinking air, the warming produced by the sinking motion is quickly used up in the evaporation of precipitation particles. If more energy is required for evaporation than is generated by the subsidence, the sinking air will be cooler than its surroundings and will continue to sink downward.

The subsiding air eventually appears below the cloud base as rounded pouch-like structures called mammatus clouds.

Mammatus are long lived if the sinking air contains large drops and snow crystals since larger particles require greater amounts of energy for evaporation to occur. Over time, the cloud droplets do eventually evaporate and the mammatus dissolve.

Our experience is the clouds look a lot cooler than can be captured on film or in electronic images.  Mr. Olsen captured a great image.

Very nice shot


Appreciating and remembering Pete Seeger

January 28, 2014

Interesting morning.  Is there anyone who does not have a Pete Seeger memory?

The Pete Seeger Appreciation page was set up many months ago — in fact founder Jim Capaldi died last December, with his family carrying it on.  A good place to start, maybe.

Classic Pete Seeger photo -- from the 1950s?  This and more at the Pete Seeger Appreciation Page, at PeteSeeger.net

Read his biography, perhaps?

Learn to play the banjo:

This is the one that made me shed tears:

What great tributes have you seen to Pete today?  Give us a link in comments, share the good stuff.


Pete Seeger and the Highlander School

January 28, 2014

It’s a stunning photograph, not for its photgrapher’s skills, nor the artistic nature of the taking.  It’s a true snapshot.  Five people on a farm in Kentucky, in black and white.  Probably the photographer used a Kodak camera made just for snapshots.

Except, it was 1957.  The farm is the Highlander School.  The five people in the photo include folksinger Pete Seeger, and Rosa Parks, and the Rev. Dr. Martin Luther King, Jr.

Who was the photographer?  Perhaps Myles Horton, the director of the school (and Charis’s husband).

In a sort piece filmed at his home in Beacon, New York, for the Highlander’s 75th Anniversary in 2007, Pete described the time and the occasion.

Don’t  you love the cricket singing along with Pete?

Farewell, Pete Seeger

January 28, 2014

Just got the news that Pete Seeger died.  He was 94.

Such a loss for American music, to American music, and to history and art.

New York Times story here.

Pete Seeger at the Beacon Sloop Club in Beacon, N.Y., in 2010. Andrew Sullivan for The New York Times

I love the Andrew Sullivan photo the New York Times used — it reminds me of the best way to hear Pete, in the out-of-doors, near the Hudson, in the summer, with a small audience who could be coerced to sing along.

Pete was an alumnus of Camp Rising Sun (of the L. A. Jonas Foundation) near Rhinebeck, New York, from the very early days.  In 1974, between concerts at large venues with Arlo Guthrie, and on his way back home to Beacon, Pete stopped and spent a day with us at the camp.  He was , as always, wonderfully gracious, other than outward appearances indistinguishable from the 14- and 15-year boys in excitement to be having fun, exploring nature, and then leading us all in songs.

My unfinished master’s thesis was to explore Pete’s use of different rhetorical devices to get his messages across, and make them popular.   (One of my everlasting regrets.)

But despite his down-home-everybody-welcome demeanor, Seeger drove great movements, and pushed the arcs of history in wonderful directions throughout his life.

  • Pete was an anchor for Woody Guthrie in New York, and sometimes a rival.  As Pete told it, everybody loved Woody and always came to a performance to hear Woody sing.  It was often Pete who pushed Woody out front; no mistake that Woody’s famous New Year’s resolutions from 1942 included “Love Pete” among them.
  • Having learned from the Lomaxes at the Library of Congress, Pete recorded history in songs, preserving old tunes, making foreign tunes popular, and re-arranging verses here and there.  Pete revealed, discovered, or pushed the music of a family domestic (“500 Miles”), Cuban revolutionary poets (“Guantanamera”), his engineer sister (“Going to be an Engineer”), and hymn books.
  • Pete taught a song to seminar attendees at the Highlands School in Kentucky, people who went on to do great things with that song.  The song was “We Shall Overcome,” and photos show that those Pete taught to sing included both Rosa Parks and Martin Luther King, Jr.
  • Blacklisted after refusing to give in to the civil liberties assault by the U.S. House Committee on Un-American Activities (HUAC), Pete created a series of records to teach how to play a guitar, a banjo, and a twelve-string.  One of the kids who learned some twelve-string licks included a guy who went on to play strings for the folk group, the Chad Mitchell Trio, and their new tenor, a guy named John Denver.  Roger McGuinn electrified that twelve-string, and leading the Byrds, turned some of Pete’s songs into rock and roll hits — like “Turn, Turn, Turn.”
  • I asked Pete about getting him to Salt Lake City for a concert in the 1970s — he demurred, saying he needed to spend some time locally.  He told a story about showing up at a PTA meeting in Beacon to talk on some issue, and some local guy told Pete that Beacon didn’t need outsiders telling them what to do.  This hurt Pete, since he’d been living in Beacon at that time for more than 30 years, in the house he built by hand.   Pete told me that he realized a world reputation doesn’t count for much if you can’t use it to make things better in your home town.The “local project?” He said he wanted to get an old sloop, and sail the Hudson River signing to get people to clean it up.  At the time, the Hudson was very much a sewer from Albany to New York City.  A short time later the Sloop Clearwater was refitted, and Pete started music festivals up and down the river.  The Hudson, Pete’s local river, runs much cleaner today for his work.
  • I saw Pete and Arlo in concert at Wolf Trap, the performance park near Washington, D.C., a couple of times; and some other venues — but nothing ever beat that open air concert at Rising Sun.
  • Bruce Springsteen did us all a favor with his album of Seeger tunes; I chafed at Ronald Reagan’s choices of performers at his inaugurals, and at many other choices over the years.  I often thought Pete Seeger’s music, and voice, would be a better choice.  Springsteen’s pre-inauguration concert in 2008, from the Lincoln Memorial, had my full attention.  The only thing more perfect, I told Kathryn, would be Pete singing his own tunes from those steps (I heard him tell the stories of King’s and Marian Anderson’s performances there more than once).  Within a few minutes, Springsteen pulled Pete out onstage, and at the age of 90 he led the crowd singing Woody’s “This Land is Your Land.”  A perfect capstone, I thought.

If  you would, pull out your collection of Pete Seeger music today, and give it a spin.  It will raise your spirits, I guarantee.

What wonderful gifts Pete left us!

So long, Pete, one of the best American citizens we’ll ever know.

Maybe we should just say, “So long! It’s Been Good to Know Ya!”
