Boreal Summer Intraseasonal Oscillation (BSISO)

This module provides functions to calculate and visualize the BSISO, a dominant mode of intraseasonal variability in the Asian summer monsoon region during May-October. The BSISO is characterized by northward and eastward propagation of convective anomalies, influencing monsoon rainfall and tropical cyclone activity. The methodology is based on Lee et al. (2013), which defines multivariate indices using outgoing longwave radiation (OLR) and 850-hPa winds to capture BSISO phases.
