Vertical profiles of $S$ were found to be grouped into two classes that display different slopes with height: one is nearly constant and the other is increasing. This behaviour can be explained using a simple model for the PDF of vertical velocity and assuming two distinct vertical profiles of updraft area fraction from literature. The possibility of describing the explicit dependence of $K$ on $S$ was revised critically, also considering the neutral limit as ","authors_text":"Alberto Maurizi, Francesco Tampieri","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ao-ph","submitted_at":"2013-10-16T10:25:46Z","title":"Some considerations on skewness and kurtosis of vertical velocity in the convective boundary layer"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1310.4321","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":"sha256:1bb3a62af4b02fef9b3328c1e2b40a3c77dff0567d1adb19421db15b9a19443c","target":"record","created_at":"2026-05-18T03:10:23Z","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":"7ebe95b6ff6c07cd54068e58b2138ec2d52eb65940c4e0f1c481d7d24554b2f6","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ao-ph","submitted_at":"2013-10-16T10:25:46Z","title_canon_sha256":"129dce921da30a1b72d77d43f8190ec24e08e229cbab47020575b10bfd5d3d1b"},"schema_version":"1.0","source":{"id":"1310.4321","kind":"arxiv","version":1}},"canonical_sha256":"0993e0b97b573cbf6d5e972e0db05eee8a7671fda971c8f7d0ff5949ad112465","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0993e0b97b573cbf6d5e972e0db05eee8a7671fda971c8f7d0ff5949ad112465","first_computed_at":"2026-05-18T03:10:23.176456Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:10:23.176456Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fuonGkiwb7RnmBvwXeTiH9EmNczTkS5c8jKcHHp2MxOcQyRu6mZyO7sIxMcU7qK8NwwPpMQXtiNEnWHh5awkCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:10:23.177233Z","signed_message":"canonical_sha256_bytes"},"source_id":"1310.4321","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1bb3a62af4b02fef9b3328c1e2b40a3c77dff0567d1adb19421db15b9a19443c","sha256:5a9af65145bf2e24371e8aaf109a6ba2f212d4c1a579207dde32ed0db5aba7e5"],"state_sha256":"b14021d550cdc82b790f082ca1e32129b71a82cfd6276669e40f19df8327315a"}
