Replication Data for the study of the Asian Summer Monsoon Anticyclone Boundaryhttps://doi.org/10.26165/JUELICH-DATA/4BRLEMKachula, OlehJülich DATA2025-10-312025-10-31T14:23:31ZThis data set is part of the study by Kachula et. al (2025). It includes time series of the Montgomery streamfunction contour level from May to September for each day at 12:00 UTC during the period 1980-2023 at 350 K, 370 K, 390 K and 410 K, representing the boundary of the Asian Summer Monsoon Anticyclone as calculated by the proposed method. In addition, we provide the Montgomery streamfunction data defined on a regular 1° × 1° grid.Earth and Environmental SciencesKachula O., Vogel B., Günther G., and Müller R.: An optimization-based approach to track the Asian summer monsoon anticyclone across daily and interannual variabilityKachula, Oleh2025-10-31CC0CC0 Waiver
