Night Returns to Barrow, Alaska


For the past couple of years I have found many interesting sources of information.  I am going to share one of my favorites now.  Gaisma.com has a vast library of locations around the world and they show the yearly solar cycle for these locations.  I have definitely spent more time than was required just strolling through the various locations around the world and seeing how the day-night cycle behaves.

The location I have been looking at the the most northern reaches is Barrow, Alaska.  At 71.3° N latitude it is up there.  I have been taking a peak each day for the first night to return and it has finally happened.

Night once again is returning to Barrow, Alaska.

They even take into account the day-light savings.  Not that it is very useful in Barrow in November when the sun is only up for 5 hours a day.

My location is a bit more typical for the populated portion of the planet.

Nothing too extreme in my location.  For that you have to go to Antarctica and the Amundsen-Scott station down there.

Amundsen-Scott Station in Antarctica.

That location is starting to get dawn for the first time since April.  That is a long winter.  According to the same website, the average temperature there in August is -63.4 °C.  That is far colder than most people will ever experience in their lives.  Only a few people would ever want to experience temperatures that cold.

In one month the Earth will be at the transition point between the seasons.  The average temperature of the Earth will drop by 4 °C over the next 6 months and the yearly cycle will repeat as it always has.  In all of that huge swing of temperature, the anomaly will probably stay less than 0.5 °C.  It is all about the Sun and it always has been.

Also..  The edit is nearly complete and I expect that the book will be available within the next week as an eBook and in about a month as a real, hold it in your hand book.   🙂
