Role of oceanic factors:
1Indian ocean Dipole i.e. Difference in sea surface temperature of Indian ocean (west & coast) - Positive IOD facilitates Indian monsoon
3La-Nina & El Nino - Sea surface temperature when increased in coast of peru (El-Nino) & low in La-Nina. El-Nino causes Rain deficiency and drought. (current year). La-Nina - maximum rain & flood
Atmospheric factor:
1South easterly Jet stream when delayed Tibetan Plateau heat producer (SPTS) - southern side of the jet stream remained by Indian continent (Himalaya) → Hindus Monsoon.
