Alaska’s all-time cold record turns 50

Jan. 23, 2021, is the 50th anniversary of Alaska’s all-time cold temperature: minus 80 degrees Fahrenheit, recorded by a weather observer at Prospect Creek Camp. Now a clearing in the woods, Prospect Creek Camp was located near the confluence of Prospect Creek and the Jim River, just north of the Arctic Circle and about 160 miles north of Fairbanks.

Giant storms, big waves and chilly winds

…the Howard Pass weather station in the western Brooks Range recorded an air temperature of minus 33 degrees Fahrenheit. At the same time, the wind was blowing 47 miles per hour. That’s a windchill of minus 78 degrees. That inhumane condition is not unusual for Howard Pass, a relative low spot (2,062 feet) in Alaska’s farthest-north mountain range.

Cold tolerance not the same for everyone

A 9-year-old Carl Tape — now a seismologist at UAF’s Geophysical Institute — poses beside a thermometer registering 50 below zero Fahrenheit during a Fairbanks cold snap in January 1989.

Howard Pass an extreme, inviting place

Howard Pass, a rock-stubbled tundra plateau in the western Brooks Range, is one of the lowest points in the mountains that arc across northern Alaska. It is a broad gateway between the great drainages of the Colville and Noatak rivers. Scientists who have visited the lonely spot say Howard Pass is noteworthy for two reasons — it features some of Alaska’s most extreme weather and, curiously, the area has an abundance of archaeological sites.

Atmospheric rivers sometimes soak Alaska

Scientists have long noted these flood-causing/wildfire-relieving “long, narrow plumes of enhanced atmospheric water vapor.” If you were to study weather maps of the entire Earth today, you would see about 11 atmospheric rivers.

Arctic change has widespread impacts

As the Arctic warms faster than the rest of the globe, permafrost, land ice and sea ice are disappearing at unprecedented rates. And these changes not only affect the infrastructure, economies and cultures of the Arctic, they have significant impacts elsewhere as well.

New climate index based on atmospheric pressure produces more accurate predictions of storm wave conditions

A method based on the north-south atmospheric pressure gradient along the Atlantic coast of Europe could lead to enhanced forecasting of extreme wave conditions and increased preparedness within coastal communities, a new study suggests.
