Dalton Minimum bụ ógè nkè ọnụ ọgụgụ nké gbadara àlà ébé anyanwụ, na-anọchite anya ọrụ dị ala nke anwụ, nke akpọrọ aha ónyé England na-ahụ màkà ihu igwe John Dalton, nke na-adị site n'afo 1790 ruo afọ 1830 ma ọ bụ afọ 1796 ruo 1820, nke kwekọrọ na ógè okirikiri anyanwụ 4 ruo okirikiri nke anyanwụ 7.Komitov and Kaftan 2004Archibald, p. 32
Ọ bụ ezie na a na-ejikarị Dalton Minimum tụnyere Maunder Minimum, ọnụ ọgụgụ sunspot ya dịtụ elu ma kọọrọ sunspots na-ekesa na hemispheres anyanwụ abụọ n'adịghị ka Maunder Minimal.Hayakawa et al. 2020a A na-egosipụta ihe ndị na-acha uhie uhie na Ezra Ames na José Joaquin de Ferrerz na ihe osise eclipse n'afọ 1806 ma gosipụta ọdịdị nke magnetik ya ọ bụghị nke Maunder Minimum kama na nke okirikiri anyanwụ nke ógé a.Hayakawa et al. 2020b

 Okpomọkụ 
Dị ka Maunder Minimum na Spörer Minimum, Dalton Minimum dakọtara na ógé okpomọkụ ụwa dị ala karịa nkezi. N'oge ahụ, enwèrè mgbanwe nké okpomọkụ nkè ihe dịka otu Celsius na Germany.File:Temperaturreihe Deutschland.png, red line, 1795 to 1815

A ghọtachaghị ihe kpatara okpomọkụ dị ala karịa nkezi na njikọ ha nwèrè ike inwe na ọnụ ọgụgụ dị ala nke anyanwụ. Akwụkwọ ndị na-adịbeghị ányá atụwo aro na ịrị elu nkè mgbawa ugwu bụ ihe kpatara usoro oyi.Wagner and Zorita, as well as Wilson.

Ọ bụ ezie na Afọ Na-enweghị Oge Ọchịchị, n'afọ 1816, mèrè n'oge Dalton Minimum, isi ihe kpatara okpomọkụ dị jụụ nke afọ ahụ bụ mgbawa ugwu nke ukwuu n'afọ gara aga nke Ugwu Tambora na Indonesia, nke bụ otu n'ime mgbawa abụọ kachasị ukwuu n'ime afọ 2000 gara-aga. Otu ónyé ga-echekwa na ịrị elu nke mgbawa ugwu nwèrè ike ịbụ site na ọkwa dị ala nke mmepụta anyanwụ n'ihi na enwèrè njikọ na-adịghị ike ma dị ịrịba ama n'etiti mbelata nke mmepụta nke anyanwụ na mmụba nke mgbawa ọkụ.
