-as of [17 APRIL 2024]–
.
-the tropo-sphere is the lowest portion of earth’s ‘atmosphere’, and is also where nearly all ‘weather conditions’ take place-
.
(it contains approximately 75% of the atmosphere’s ‘mass’ and 99% of the total mass of ‘water vapor’ and ‘aerosols’)
(the average depths of the ‘troposphere’ are 20 km (12 mi) in the ‘tropics’, 17 km (11 mi) in the mid latitudes, and 7 km (4.3 mi) in the polar regions in winter)
(the lowest part of the ‘troposphere’, where ‘friction’ with the earth’s surface influences ‘air flow’, is the ‘planetary boundary layer’)
(this layer is typically a few hundred meters to 2 km (1.2 mi) deep depending on the landform and time of day)
(atop the ‘troposphere’ is the ‘tropopause’, which is the border between the ‘troposphere’ and ‘stratosphere’)
(the ‘tropopause’ is an ‘inversion layer’, where the air temperature ceases to decrease with height and remains constant through its thickness)
(the word troposphere derives from the greek: tropos for “turn, turn toward, trope” and “-sphere” (as in, the ‘earth’), reflecting the fact that rotational turbulent mixing plays an important role in the troposphere’s structure and behavior)
(most of the phenomena associated with “day-to-day weather” occur in the ‘troposphere’)
