Milankovitchn.

Brit.

/məˈlɑŋkəˌvɪtʃ/

Forms: 1900s– Milankovic, 1900s– Milankovich, 1900s– Milankovitch.

Origin: From a proper name. Etymon: proper name Milanković.

Etymology: < the name of Milutin Milanković (1879–1958; also transliterated Milankovich and Milankovitch), Serbian mathematician, astronomer, and geophysicist, who published theories on climate change (including Théorie Math. des Phénomènes Thermiques (1920) and Kanon der Erdbestrahlung (1941)).

Climatology.

attributive and in the genitive. Designating theories and concepts arising from Milankovitch's study of the earth's climate; Milankovitch cycle n. any of three cyclic variations in the orbit of the earth around the sun (involving respectively the eccentricity of the orbit, the obliquity of the earth's axis, and the precession of the equinoxes) which in the Milankovitch theory are associated with cyclic changes in the earth's climate. Milankovitch theory n. a theory connecting climate changes and glaciations with cyclic variations in the earth's orbit (the Milankovitch cycles).

1947 Man 47 32/2 The Milankovitch calculations of periods of minimal summer radiation in various latitudes are used to take dating back to about 600,000 B.C.

1967 R. W. Fairbridge Encycl. Atmospheric Sci. & Astrogeol. 470 The Milankovitch theory created a new problem, namely, that prior to the Pleistocene, there was no continental glaciation, whereas a simple oscillation such as its author depicted should go on indefinitely.

1974 Nature 15 Nov. 216/2 The Milankovitch hypothesis is that glaciations occur when the Northern Hemisphere receives relatively little summer heat from the Sun, because of astronomical factors that alter the orientation of the Earth's axis.

1979 Geology 7 584 Milankovitch cycle parameters may lead to glaciation through both insolation changes and geomagnetic effects on climate.

1985 Science 31 May 1082/3 The efforts to relate bulk density [in the sediment] to aspects of particle size,..pollen stratigraphy, and Milankovich cycles are ingenious.

1996 New Scientist 6 Jan. 31/3 There are other difficulties in the pipeline, such as irregularities in the precession of the equinoxes. These are caused by occasional glitches, called Milankovitch shifts, in the tilts of the Earth's axis.
