Data and code supporting "Increase in Large-Scale Precipitation Over the Northern Tibetan Plateau Associated With the Atlantic Multidecadal Oscillation"

This archive contains processed data and Python scripts supporting the manuscript “Increase in Large-Scale Precipitation Over the Northern Tibetan Plateau Associated With the Atlantic Multidecadal Oscillation.” The processed data include the 1980–2019 regional large-scale precipitation event catalog and LSP1/LSP2 weather-type classifications, event-level AMO and weather-type data, pre-event circulation indices, and statistical results including correlations, interaction models, and false-discovery-rate-adjusted significance values. The Python scripts support the principal analyses of event identification and clustering, weather-type composites, precursor circulation evolution, frequency and per-event precipitation analysis, event-conditional logistic regression, and AMO-related circulation and wave-activity-flux diagnostics. The original CRA-40, ERA5, ERSSTv5, and climate-index products are not redistributed in this archive and are available from the official sources cited in the manuscript. Users should modify the input and output paths in the scripts according to their local data directories.
