This approach, inspired by modeling ideas of Barndorff-Nielsen and Schimgel, is coherent with the K41 hypothesis of local isotropy, and it allows us to separate second-order statistics from higher order ones. The model can be motivated by Taylor's hypothesis and a relation between time and spatial spectra. Second order statistics are used to separate the deterministic kernel function and the weakly stationary driving noise. A non-parametric estimation method for the turbulence intermittency is suggested.","authors_text":"Claudia Kl\\\"uppelberg, Vincenzo Ferrazzano","cross_cats":["physics.flu-dyn"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.data-an","submitted_at":"2012-05-30T10:04:24Z","title":"Turbulence modeling by time-series methods"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1205.6614","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:f32623dde07394c56ad197f0d82d40d1f307282bd15a3dbd3e5383390fce9f02","target":"record","created_at":"2026-05-18T03:54:38Z","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":"528186d94235f12cbf4adf5c84bd84411c6047371e7fcd87bdf8d5ef0c61eb70","cross_cats_sorted":["physics.flu-dyn"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.data-an","submitted_at":"2012-05-30T10:04:24Z","title_canon_sha256":"b861a23a2b30533ffc0d8ec2c447f1fcb2a3959bcbc142aa05a3f538f0a0e39a"},"schema_version":"1.0","source":{"id":"1205.6614","kind":"arxiv","version":1}},"canonical_sha256":"d648d7f603eedf6ffa6641a8016dab9d9ad3c7e8cf305283597f1a17d98d68cb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d648d7f603eedf6ffa6641a8016dab9d9ad3c7e8cf305283597f1a17d98d68cb","first_computed_at":"2026-05-18T03:54:38.421441Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:54:38.421441Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bKfa5KgoVYlXvOIdsj9Ogse2M1Ese1j+lDyUzvURZwcb49LZ96S372UhGcm1hBe8TUzwD0OSU5WWUHse3/RXBg==","signature_status":"signed_v1","signed_at":"2026-05-18T03:54:38.422037Z","signed_message":"canonical_sha256_bytes"},"source_id":"1205.6614","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f32623dde07394c56ad197f0d82d40d1f307282bd15a3dbd3e5383390fce9f02","sha256:42e1a1a7162f958514fa59097df69cc75db8ec51440fc7e9313d3658d4424ae1"],"state_sha256":"4a9a78173e210d43cc9eceb479baea3cb8e82aea8ec3fd85248b75d36fc6d4ad"}
