There have been at least six recorded occurrences of past eruptions, and the most recent one was in 2010, with its whole life span captured by the Cassini mission. In 2015, we used the Very Large Array to probe the deep response of Saturn\u2019s troposphere to the giant storms. In addition to the remnant effect of the storm in 2010, we have found long-lasting signatures of all mid-latitude giant storms, a mixture of equatorial storms up to hundreds of years old, and potentially an unreported older storm at 70\u00b0N. We derive an ammonia anomaly map that shows an extended meridional migration of the storm\u2019s aftermath and vertical transport of ammonia vapor by storm dynamics. Intriguingly, the last storm in 2010 splits into two distinct components that propagate in opposite meridional directions, leaving a gap at 43\u00b0N planetographic latitude.<\/jats:p>","DOI":"10.1126\/sciadv.adg9419","type":"journal-article","created":{"date-parts":[[2023,8,11]],"date-time":"2023-08-11T17:59:32Z","timestamp":1691776772000},"update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":12,"title":["Long-lasting, deep effect of Saturn\u2019s giant storms"],"prefix":"10.1126","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8280-3119","authenticated-orcid":true,"given":"Cheng","family":"Li","sequence":"first","affiliation":[{"name":"Climate and Space Sciences and Engineering, University of Michigan, Ann Arbor, MI, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4278-3168","authenticated-orcid":true,"given":"Imke","family":"de Pater","sequence":"additional","affiliation":[{"name":"Department of Astronomy, University of California, Berkeley, Berkeley, CA, USA."},{"name":"Department of Earth and Planetary Science, University of California, Berkeley, Berkeley, CA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6293-1797","authenticated-orcid":true,"given":"Chris","family":"Moeckel","sequence":"additional","affiliation":[{"name":"Department of Earth and Planetary Science, University of California, Berkeley, Berkeley, CA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9209-7716","authenticated-orcid":true,"given":"R.
