A positive IOD is characterized by cooler than normal sea-surface temperatures in the western tropical Indian Ocean.

This statement is incorrect. A positive Indian Ocean Dipole (IOD) is characterized by warmer-than-normal sea-surface temperatures in the western tropical Indian Ocean.

A positive IOD can bring good rains to India despite an El Niño year.

This statement is correct. A positive IOD is often associated with increased rainfall in the Indian subcontinent, even during El Niño years. It can act as a counterforce to the suppressive influence of El Niño on the Indian monsoon.

Therefore, the correct option is 2 only.
