According to scientists, two other major weather phenomena are also contributing to the weak monsoon and the rise in temperatures across Karnataka.
Indian Ocean Dipole (IOD) Remains Neutral
The Indian Ocean Dipole (IOD) plays a crucial role in strengthening the southwest monsoon. However, it is currently in a neutral phase because of near-normal sea surface temperatures. As a result, the monsoon has not received the additional support required to strengthen rainfall.
Madden-Julian Oscillation (MJO) in an Unfavourable Phase
The Madden-Julian Oscillation (MJO), a large-scale atmospheric phenomenon that influences rainfall across India, is currently positioned over the eastern Pacific Ocean. This unfavourable phase is suppressing the development of monsoon systems over India, resulting in reduced rainfall and prolonged dry conditions.
