This inheritance leads to a dominant paradigm of learned autoregressive time-stepping and constrains how the learning problem is defined and architectures are favored. In this study we make the inheritance explicit, contrast two philosophical traditions: \"scientific surrogate modeling,\" where machine learning (ML) is embedded within a physical system and must respect its structural constraints, and \"free-form data-driven modeling,\" where atmosph","authors_text":"Mohammad Hassan Erfani","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.ao-ph","submitted_at":"2026-07-06T13:21:13Z","title":"On the Genealogy of Machine Learning Weather Prediction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.05045","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":"sha256:612bbd5684577b1cab5333a5e7fd1fe76f7286b799bc73d6ffb6a9f4db168035","target":"record","created_at":"2026-07-07T02:20:20Z","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":"50d6b1fae1a7b0fc2b955e44a1ef23d0aac8496bb83da32300eb35580d2f0edb","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.ao-ph","submitted_at":"2026-07-06T13:21:13Z","title_canon_sha256":"d5c84d125d9840cb4ea50797b08d8c0e5ab122394fbc12d13e0beefc5a9ed107"},"schema_version":"1.0","source":{"id":"2607.05045","kind":"arxiv","version":1}},"canonical_sha256":"3eab650493780a8070a612fc340210332d908f4dd33f3e97aca04acda7d638db","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3eab650493780a8070a612fc340210332d908f4dd33f3e97aca04acda7d638db","first_computed_at":"2026-07-07T02:20:20.327139Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-07T02:20:20.327139Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"drEMqR6GbSM+37mbp0+0zHRLcL+qiio7seK+kR7oZ9Tj3ABPjVsOAann8kn78bxqxlrJ7a1Z4cI7j+zGP94WBg==","signature_status":"signed_v1","signed_at":"2026-07-07T02:20:20.328131Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.05045","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:612bbd5684577b1cab5333a5e7fd1fe76f7286b799bc73d6ffb6a9f4db168035","sha256:f144246957ee1a2fb0d55a12665a87d3b48079513ed5d2362e6a04d9b6858c2f"],"state_sha256":"2c8e2791326daada46d1e6ca800b065814766218aa0ba785322b1f83f0f0b68f"}
