Chinook permits wearing non-seasonal clothes
The Chinook is a Föhn wind. In Interior Alaska, we get Chinooks, when a low pressure system in the Gulf of Alaska travels north over the Alaska Range. Chinook means “snow-eater”. Its air is warm and dry as during Chinook episodes a lot of the water load falls out on the southern exposed mountains of the Alaska Range.
Typically, temperature decreases with height. As the air ascends on the southern side of the Alaska Range, the condensation of water vapor to form cloud drops and ice crystals released heat and hence warms the air. Consequently, temperature decreased less strongly with height than without condensation and than for dry air. When the water rained out on the southern side, the air is dry when it decends on the northern side. Thus, temperature increases more strongly during the descend than it decreased when ascending on the sourthern side. Thus, when reaching the bottom of the valley the air is warmer than it was at same height on the other side of the mountains.
Chinnoks occur at all times of the year. In winter, Alaskans may even don bare legs during a Chinook event. This time, the Chinook set in over night. The warm, dry air that made it over the Alaska Range, hence, melted and sublimated the snow away.
Dry air means a great view on the Alaska Range from Fairbanks
Thanks to the dry air, one can see the northern mountains of the Alaska Range in the outfit photos. These mountains are more than 80 miles away. Thus, this day had a great visibility because the water vapor content of the air was very low and there were hardly any particles in the air.
Fall business casual work outfit
Since temperatures were in the 50s (10oC), I could wear my light long leather coat for the commute to work. Under my coat, I wore the leather carpi from summer with a fuchsia cardigan tucked in as a top, and a corduroy bottle-green blazer to give the outfit a fall vibe. I added my nude fuchsia-orange pumps for an office appropriate look. It is the second time that I styled this capri for a fall work outfit.
Are you still wearing clothes from summer or has fall’s chilly air already asked for winter clothes? Let me know, I am curious what you are wearing at this time a year.
