1925 Geografiska Annaler 7 151 Let us emphasize that any discussion of the so-called wave-theory of cyclogenesis will remain futile as long as the mathematical treatment of the subject is as incomplete as at present.

1978 Jrnl. Atmospheric Sci. 10 Aug. 576/2 Studies so far on monsoon cyclogenesis have shown that the monsoon atmosphere is not baroclinically unstable.

2000 C. D. Whiteman Mountain Meteorol. v. 50 A weak cyclogenesis center (not shown in the figure) is also found in the lee of the Sierra Nevada.

2015 Telegraph (Nexis) 9 Jan. I don't like the expression ‘weather bomb’–it sounds far too dramatic. The true description of this miserable January weather should be ‘explosive cyclogenesis’, which is less terrifying and more accurate.

This is a new entry (OED Third Edition, June 2015; most recently modified version published online March 2022).
