Tuesday marked the 200th day in a row of above normal temperatures for Alaska. Even in a string of unusually warm years for the state, that’s a remarkable run.
Brian Brettschneider is a climatologist in Anchorage who closely tracks Alaska climate data and trends. Alaska’s Energy Desk is checking in with him regularly as part of a new segment- Ask a Climatologist.
The daily average statewide temperature is based on an index of 25 cities across Alaska.
Interview transcript
Brian: Individual cities may have a few below normal days sprinkled in here and there, but on the aggregate it’s been above normal every single day of 2016 except for one and that was Feb. 9.
Annie: And how unusual is that?
Brian: The last two years, 2014 and 2015, were the two warmest years on record, dating back to 1925, when they started keeping stats. Each of those two years had at least 60 days that were in the lowest third of temperature categories. And this year we’ve had no days in the lowest third of temperature categories and only one day that was even slightly below the normal. So it’s almost a near certainty that 2016 will be the warmest on record for Alaska.
Annie: And we keep talking about these warm ocean temperature around Alaska. How much is that a factor?
Brian: Well it’s definitely a factor. You’ve got this unlimited reservoir of warm ocean water which facilitates warm temperatures in the air right above that water, so it really acts as a floor for how low temperatures can go.
Annie: And what are you seeing in the August data for those ocean temperatures?
Brian: For the ocean temperatures surrounding Alaska, and I’m talking mainly south- so Gulf of Alaska, Bering Sea- the summer of 2016 was the second warmest on record. Last year was the warmest on record. And 2014 was the third warmest on record. So it really goes to show how anomalously warm the atmosphere and the environment is around Alaska that really is preventing us from having even normal temperatures.
