We consider three models of large-scale dissipation: linear \"Ekman\" drag, non-linear quadratic drag, and scale selective hypo-drag that damps only low-wavenumber modes. In all cases, the statistically steady vorticity field is dominated by almost axisymmetric vortices, and the probability density function of vorticity is non-Gaussian. However, in the case of linear and quadratic drag, we find that the v","authors_text":"Yue-Kin Tsang","cross_cats":["physics.ao-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2017-03-20T23:17:25Z","title":"Non-universal velocity probability densities in two-dimensional turbulence: the effect of large-scale dissipation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1703.07000","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":"sha256:8d11860e227600232cf88c6e275d459eba35d97b9c707a874d0e4eeb4e1083aa","target":"record","created_at":"2026-05-18T00:48:09Z","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":"b09d074deacab7054b594e2df9109a01591a809e8b31001d8a99b0b6b87c3a62","cross_cats_sorted":["physics.ao-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2017-03-20T23:17:25Z","title_canon_sha256":"1f8ba429fa009ce7404fefbbc32e581410012c16ecbe67ba0d63c8f4da4064b2"},"schema_version":"1.0","source":{"id":"1703.07000","kind":"arxiv","version":1}},"canonical_sha256":"e276bb297cca3e4a8f51a103a22c9fbb30dcaddc0c3488a69033bee50584f7e2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e276bb297cca3e4a8f51a103a22c9fbb30dcaddc0c3488a69033bee50584f7e2","first_computed_at":"2026-05-18T00:48:09.066162Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:48:09.066162Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wtw1/UC/yEwM2ZbwfHig6v7KcB1oF2vXpthG0qaQ55u8yNjBKgFVm3H0x22eXXKPPczy84NN172rA+dJCb4dDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:48:09.066759Z","signed_message":"canonical_sha256_bytes"},"source_id":"1703.07000","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8d11860e227600232cf88c6e275d459eba35d97b9c707a874d0e4eeb4e1083aa","sha256:af521dea3a03e3f08d9e4dd6c3fd779354936e192727e4bc881296018498b52b"],"state_sha256":"662f0cf87f940e45a940a89fa1d86ac18b149b6903b26541c8c622e34ffa7925"}
