New Research Paper out on Denali

We present the data records and station history of an automatic weather station (AWS) on Denali Pass (5715 m MSL), Alaska. The station was installed by a team of climbers from the Japanese Alpine Club after a fatal accident involving Japanese climbers in 1989 and was operational intermittently between 1990 and 2007, measuring primarily air temperature and wind speed. In later years, the AWS was operated by the International Arctic Research Center of the University of Alaska Fairbanks.

Arctic Sea Ice Extent: January 21, 2021

January 21, 2021: Over the past week, the sea ice has now increased from last week by a slightly higher rate of 3.01% from the level on 01/14/2021 of 13.399 M km2 to 13.753 M km2. The Arctic sea ice increase is still building, but slowly.

2019 Alaska Climate Summary

Statewide 2019 Year in Review

  • New temperature records were set: 2019 was the warmest year in Alaska since 1949, with a mean temperature of 37.4 °F, breaking the previous record set in 2016 by 0.2 degrees. All first order stations recorded positive departures from normal annual temperatures.
  • The Panhandle and Northeast Gulf were drier than normal, contributing to the most significant drought conditions observed over Southeast Alaska in the 20-year history of the drought monitor.
  • The southern coast experienced below average snowfall totals every month during the 2018/2019 winter season. Conversely, Bettles, Nome, Kotzebue, and Utqiaġvik received above average snowfall for the season.
  • The 2019 Alaska wildfire season caused many residents across the state to be evacuated. There were 719 fires recorded throughout the warm season; 2.5 mio acres of land burnt. Alaska's statutory wildfire season was extended from Aug. 31 to Sept 30 because of high fire danger due to continued warm, dry conditions into September.
  • A new "blob", or large area of warm water observed in the Gulf of Alaska, named the Northeast Pacific Marine Heatwave of 2019, formed in May 2019 and reached its maximum size in August. It has since decreased in size and intensity, but is still one of the most significant events seen in the past 40 years.
  • The September minimum sea ice extent tied with 2007 and 2016 for the second lowest sea ice extent in the 41-year satellite record at 4.15 million square kilometers.
