Tracks of Indian Summer monsoon Low-Pressure Systems from ERA5

This repository contains the codes and dataset as explained below:

1) This dataset contains downstream and in situ LPS tracks over the Bay of Bengal (BoB) classified using the algorithm developed by Srujan et al. (2021) from 1979-2017 using the ERA5 reanalysis dataset. The LPS are tracked from mean sea level pressure (MSLP) using the algorithm developed by Praveen et al. (2015).

2) This also contains Principal components (PCs) of Rossby filtered OLR. 

3) The code to compute Transfer Entropy between PC1 of Rossby filtered OLR over West Pacific region and MSLP anomaly over BoB. 

4) Codes and data to perform Kolmogorov Smirnov (KS) test.
