- Shift of Westerlies northward of Indian landmass
- Indian Ocean Dipole

Select the correct option from the codes given below:
First statement is incorrect because it is not La-Nina, but El-Nino, which is responsible for sudden change. Indian Ocean Dipole is an El Nino-like phenomenon in the Indian Ocean for shorter period whencompared to El-Nino which has a life span of 12-18 months.But IOD is not held responsible for warmer winter temperature.
