The interaction between subpolar and subtropical jet stream leads to extreme rainfall events over North India in 2013 and 2023

..ini.csv: These files contain the starting location of the Lagrangian trajectories

..out.csv: These files contain the ending location of the Lagrangian trajectories

..run.csv: These files contain the trajectory location at each spatial grid crossing

era5_air*.csv: These are the trajectory files for the simulation where we have backtracked the upper level air southwards to identify the subpolar and subtropical jet stream interaction

era5_north_air*.csv: These are the trajectory files for the simulation where we have backtracked the upper level air northwards from the flood locations to identify the wind pathways responsible for upper level meridional wind divergence.

era5_water*.csv: These are the trajectory files for the simulation where we have backtracked the surface precipitation to identify atmospheric water sources and pathways.
