mesospheren.

Brit.

/ˈmɛsə(ʊ)sfɪə/, U.S.

/ˈmɛzəˌsfɪ(ə)r/; see also meso- comb. form.

Origin: Formed within English, by compounding. Etymons: meso- comb. form, -sphere comb. form.

Etymology: < meso- comb. form + -sphere comb. form (see quot. 1939 at sense 1). Compare French mésosphère (20th cent.).In sense 2 apparently an independent formation (see quot. 1950 at sense 2).

1. Geology. Originally: the middle layer of the earth's interior between the core and the crust; the earth's mantle. Later: the layer of the upper mantle immediately below the lithosphere; (also) the layer of the mantle immediately below the asthenosphere.

1939 H. S. Washington in B. Gutenberg Internal Constit. of Earth v. 92 There would be some advantage in using the terms kentrosphere for the core or nucleus, mesosphere for the intermediate shell and perisphere for the uppermost layer or crust.

1968 Jrnl. Geophysical Res. 73 5856/2 The lithosphere and the mesosphere have relatively high seismic velocities and propagate seismic waves without great attenuation.

1990 P. Kearey & F. J. Vine Global Tectonics viii. 149 The bottom of the plate approaches the mesosphere, which resists descent and throws the leading tip into compression.

1999 Encycl. Brit. Online (Version 99.1) at Earth Other investigators hold that the lithosphere moves along with the asthenosphere (the relatively plastic layer underlying the lithosphere) and perhaps the top of the mesosphere as well.

2. Atmospheric Physics. The region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 50 and 80 km (30 and 50 miles) in altitude, in which the temperature decreases with height.

1961 New Scientist 30 Nov. 568/3 Winds at heights of 80 to 100 km in the Earth's atmosphere—in the so-called mesosphere.

1973 Physics Bull. Dec. 727/1 The fifth experiment aboard Concorde concerned emission from the stratosphere and mesosphere arising from the electronic transition between the metastable ¹Δ_g and the ground ³Σ⁻_g states of molecular oxygen.

1994 Sci. News 18 June 397/1 Noctilucent clouds develop in the mesosphere at an altitude of 85 kilometers.
