In summer, however, the top of Mount Tamalpais may actually be warmer than the middle, foggy elevations due to a thermal inversion.
12.
In addition, during the flight an unusual thermal inversion occurred; the temperature rose with altitude, which the pilot could not have predicted.
13.
Pollutants are trapped in the volcano-ringed 7, 400-foot-high valley, especially in the colder winter months when thermal inversions keep them from dispersing.
14.
March and April saw a total of just 13 smog-trapping thermal inversions this year, compared to 29 in the same months last year.
15.
Thermal inversion is the name of the wintertime weather event that turns the air over Mexico City into a grayish-yellow pudding of pollutants.
16.
But if winds die down or turn, Paris, like other European cities, has thermal inversions on winter days and a soupy smog in mid-summer.
17.
While a thermal inversion often takes place without there being an atmospheric duct, an atmospheric duct cannot exist without there first being a thermal inversion.
18.
But if the western breezes die down or turn, car fumes are trapped in thermal inversions in winter or make for a soupy summer smog.
19.
While a thermal inversion often takes place without there being an atmospheric duct, an atmospheric duct cannot exist without there first being a thermal inversion.
20.
Thermal inversions occur primarily during the Winter when cool air sinks and gets trapped in the valleys at night, often leading to frost and occasional freezes.
