We discuss the reasons for the shortcomings of the 1993 model and propose what is believed to be a new model of the ST wave structure function. This model maintains the same level of computational complexity as the 1993 model but shows better agreement with the simulation results.\n                  <\/jats:p>","DOI":"10.1364\/josaa.608506","type":"journal-article","created":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T17:00:09Z","timestamp":1786122009000},"page":"1538","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Short-term turbulence beam spread revisited"],"prefix":"10.1364","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8315-8254","authenticated-orcid":true,"given":"Mikhail","family":"Charnotskii","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,9,4]]},"reference":[{"key":"josaa-43-10-1538-R1","doi-asserted-by":"publisher","first-page":"43","DOI":"10.1007\/BF01031475","type":"journal-article","volume":"13","author":"Kon","year":"1970","journal-title":"Radiophys.
