We find that the network correlates with the North Atlantic Oscillation (NAO), both locally in the north Atlantic, and through coupling to the southern Pacific Ocean. The existence of tele-connection links between those areas and their stability over time allows us to suggest a possible physical explanation for this phenomenon.","authors_text":"Avi Gozolchiani, Oded Guez, Shlomo Havlin, Yang Wang, Yehiel Berezin","cross_cats":["physics.geo-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ao-ph","submitted_at":"2013-09-07T20:46:14Z","title":"Global Climate network evolves with North Atlantic Oscillation phases: Coupling to Southern Pacific Ocean"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1309.1905","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:eaaf2708f2d24cafc5c6b106b5bc4579f2934d86d86f5a2f7a757c9b83057ae6","target":"record","created_at":"2026-05-18T01:47:48Z","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":"c39ca2ce25b7ee9716914f364b7ec9d54095b6eba654cd39a75c6a88fd130acf","cross_cats_sorted":["physics.geo-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ao-ph","submitted_at":"2013-09-07T20:46:14Z","title_canon_sha256":"7a4720ca9dc4b386e32c873140371d62d41be4ffaa380b7682edc8de9ded9f50"},"schema_version":"1.0","source":{"id":"1309.1905","kind":"arxiv","version":1}},"canonical_sha256":"bfc67875eb3c88dc97cf3706ec955bd4f5f3d6b1ba30b0964f8bb8716c41887e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bfc67875eb3c88dc97cf3706ec955bd4f5f3d6b1ba30b0964f8bb8716c41887e","first_computed_at":"2026-05-18T01:47:48.714840Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:47:48.714840Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QS628WYazFNcFBeMGEM1Tp5q6d/F8P5K28+MycMBSSBbNmkLmc5I1sEafL6PFzoJoEKNotoaKg0nS828tpVoBg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:47:48.715353Z","signed_message":"canonical_sha256_bytes"},"source_id":"1309.1905","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:eaaf2708f2d24cafc5c6b106b5bc4579f2934d86d86f5a2f7a757c9b83057ae6","sha256:d346ce11818815106b85eda31ca33a357d0a59c7554bdae3ce09a1d83e5e77be"],"state_sha256":"3636e91ed747a80bf832303e4db099c0a7ed6b12909db9d9761fb4d130045ffb"}
