Overview

Analysis classifies winter extreme precipitation events by synoptic pathways, indicating dynamic origins and trends.

Key Points

  • Type 1 precipitation events have declined, while Type 2 events show a significant increase in frequency over recent decades.
  • Type 1 events are associated with a Rossby wave train from western North America, leading to cyclonic anomalies over the Tibetan Plateau.
  • Type 2 events are driven by a mid-latitude Rossby wave train, generating ascent and moisture concentration within the western Tibetan Plateau.
  • Understanding these pathways can enhance predictions of extreme weather events and their climate implications.
