Alaskan ‘weather nerds’ revel in information-packed climate book
Published Sunday, February 17, 2008
If you like gardening, you might scratch Barrow off your list of places to live. Alaska’s farthest north town experiences about 10 frost-free days each year. Also, you would have trouble watering your plants there, especially in 1934, when an Alaska-record low 1.4 inches of precipitation fell — all year.
In stark contrast, your broccoli would have needed an umbrella in Angoon on an October day in 1982, when 15 inches of rain fell. And you probably needed more than a shovel if you were driving through Thompson Pass at the end of December in 1955, when more than 5 feet of snow fell in one day.
On the bright side for Barrow, its citizens are gaining 15 minutes of sunlight every day right now, in early February, while Annette in Southeast Alaska gains just four minutes per day. And Barrow is also a great place to fly a kite; the town experiences calm conditions just 1 percent of the time.
I know these things because I own a copy of “The Climate of Alaska,” a book by Martha Shulski and Gerd Wendler, two climatologists who work for the Alaska Climate Research Center. The University of Alaska Press just published their new book, which is packed with cool facts about Alaska for weather nerds like me and anyone else who wants to learn more about this “large peninsula” we call home.
Shulski and Wendler have gathered all the reliable weather records — most of which are younger than a century old in Alaska — and have written about trends and oddities, like the fact that the farthest north tornado swept through the village of Kiana in August 1976.
“The Climate of Alaska” exposes the extremes of Alaska, including the facts that it didn’t snow or rain in Gulkana for two months straight in 1950, and in 1999 it didn’t stop raining for 49 consecutive days in Juneau. Gah.
As the Juneau example illustrates, the book gives you a decent feeling of what it might be like to live in different areas of the state. People in Anchorage, for example, can see 39 miles on an average day. Fairbanks has a daily average of 35 miles visibility, but it might be tough to be a Cessna pilot in St. Paul, where the average visibility is 6 miles.
The state capitol for sunny days is Kotzebue, which features an average of 100 days each year with clear skies. If you were into clouds, Cold Bay would be the place to be, with an average of just 13 clear days each year, and an average of zero clear days in June, July, August and September.
If you get the chills thinking about Cold Bay, Southeast’s Annette is the state’s warmest town, based on its yearly average of about 46 degrees Fahrenheit (This is due to its stable, maritime climate. If you really want heat, the town with the warmest average high temperature in July is Fairbanks, at 73 degrees). The coldest town with long-term weather records is Barrow, with an average yearly temp of 10.4 degrees.
We all hear that Alaska’s climate is changing, and no one can tally that up with more certainty than a couple of climatologists. Shulski and Wendler found that from 1949 to 2005, the state warmed 6.3 degrees Fahrenheit in winter, 4 degrees in spring, 2.3 degrees in summer, and just 0.9 degrees in autumn. Every major town and city in Alaska with a dependable weather record for that half century got warmer during every season, except Bethel, Delta, and Fairbanks, which cooled ever so slightly in the fall.
“The Climate of Alaska” is now available in Fairbanks bookstores, or on the Web from the major booksellers. After you buy one, you can tell me which Alaska town is the foggiest (hint: it begins with a B and it’s hard to grow tomatoes there).

I almost want to buy that book, since I am a weather freak. Good article too, makes it even more tempting for me. I just wanted to make sure the global warming crowd doesn't jump too high about the last couple paragraphs. One major point they forgot to mention is though the temperatures did rise in the last fifty years, I believe it was the period beginning in 1977 or 78 that had the most change. Temps for the 30 years before that were colder than 'average'. Also, the data in Alaska is not that reliable because of the amount of data. Many stations don't even have a full hundred years of data and those that do are limited. Even so, 100 years climatologically are not that significant. So yes Alaska is warmer on average, but that doesn't necessarily prove much more than the fact that the pattern changed. Why is to be left up to scientific interpretation I guess.
