Developing turbulence closures remains one of the most challenging problems in fluid dynamics. Specifically, the Navier-Stokes equations, when filtered to isolate large-scale motions, introduce new terms representing the influence of subgrid-scale turbulent stresses. These terms, which can only be computed directly by resolving the turbulence itself, therefore lead to the closure problem: we must add new equations o","authors_text":"Laure Zanna, Pavel Perezhogin","cross_cats":["physics.ao-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.flu-dyn","submitted_at":"2026-06-18T19:56:46Z","title":"Towards bridging the gap between data-driven and theoretical turbulence closures in stratified flows"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.20901","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:098ab32b14062158fbc52c6a287d1ba9e3c3670706a36af4bc1d43c0593bae96","target":"record","created_at":"2026-06-23T01:12:21Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"6d09a30362ef4664cd5584cb9487a4a950d47c9acaa2be30a35d00b9c4dd68b6","cross_cats_sorted":["physics.ao-ph"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.flu-dyn","submitted_at":"2026-06-18T19:56:46Z","title_canon_sha256":"4d3759fcd88c89f82be30540b94359bc2fb4876e15b955cfec8db1b2592c3151"},"schema_version":"1.0","source":{"id":"2606.20901","kind":"arxiv","version":1}},"canonical_sha256":"6c34f1addfb48a748a088596ba049a3808b9b2e01babc9ac0999429918cbbea5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6c34f1addfb48a748a088596ba049a3808b9b2e01babc9ac0999429918cbbea5","first_computed_at":"2026-06-23T01:12:21.275907Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-23T01:12:21.275907Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"g8l+GN/ju1Z8536g2s6OFFPvwF04UfMG93809AbSAshm4pG/fH9sn3yrGZZ9zHsa2ACZBfYiCKYsK6C88/pPBQ==","signature_status":"signed_v1","signed_at":"2026-06-23T01:12:21.276596Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.20901","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:098ab32b14062158fbc52c6a287d1ba9e3c3670706a36af4bc1d43c0593bae96","sha256:3759fd5e15488921ed26135425881dc87c67c61ab86f43d3cbd9105c63b14527"],"state_sha256":"b9dcf6be9d1bcf74ee7102874092ac3afcca0ccdf64e19508c42ef64502cceb0"}
