Quite unusual to document a situation of thermal inversion of this magnitude, as unusual is the type of measurement with which it was carried out. A measure in motion.
Very extreme inversion recorded during a on the go session in the Fairbanks area (Alaska) on January 26 2021!
A difference of as much as 19.2° C (34.5° F) over a distance of approximately 5 km (3.1 miles), with an unbelievable temperature variation from -33.3° C (-27.9° F) to -14.1° C (6.6° F), was detected at around 9 A.M. Alaska time.
The analysis performed on the MeteoTracker web platform (vertical profile graph and other tools) shows very well how strong the positive vertical temperature gradient was.
