We demonstrate how the non-Boussinesq term of the baroclinic torque acts against the Boussinesq one to hinder wave propagation. By standard vorticity inversion and mirror imaging, we then show how the existence of the bottom boundary affects the two types of torque. Since the opposing non-Boussinesq torque results solely from the mirror image, it vanishes in the deep water limit","authors_text":"Anirban Guha, Eyal Heifetz, Ron Maor","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2019-03-13T14:46:59Z","title":"On the opposing roles of the Boussinesq and non-Boussinesq baroclinic torques in surface gravity wave propagation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.05518","kind":"arxiv","version":2},"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:a44ea57dd5e291d40469f24e7a196784180b7499129295e4b2838ea644528501","target":"record","created_at":"2026-07-05T00:56:24Z","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":"c8a577275814f11a7da02033d659a116b3086bcedfce82b7784e38701d7cb779","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2019-03-13T14:46:59Z","title_canon_sha256":"e22ff8c88bf0e9df2b053363295a0173d7d6117a29df1edb2ca1fa8a906377ec"},"schema_version":"1.0","source":{"id":"1903.05518","kind":"arxiv","version":2}},"canonical_sha256":"5da12a0940038026c8ae6bcf689ed8147a7e03d8660bbfe5ad063e5e72dedd61","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5da12a0940038026c8ae6bcf689ed8147a7e03d8660bbfe5ad063e5e72dedd61","first_computed_at":"2026-07-05T00:56:24.354858Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:56:24.354858Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"v4ePBy4psbprv4a+8Kmp7Sszgqqc99iMjkD2BFI2orSsI9qtaGq3/kEuH0GuO5uI8K6IfwdyuzHqAi1v6G04Dw==","signature_status":"signed_v1","signed_at":"2026-07-05T00:56:24.355355Z","signed_message":"canonical_sha256_bytes"},"source_id":"1903.05518","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a44ea57dd5e291d40469f24e7a196784180b7499129295e4b2838ea644528501","sha256:f00f156630dcecd117bc5e0cd11736a2096607eb6a5037dabc8edeabbfb5705b"],"state_sha256":"388391064ac36ac1333d5aee593e5985c679472963acbf217916f0c06e68a20e"}
