With reference to Ocean Mean Temperature (OMT), which of the following statements is/are correct?

OMT is measured up to a depth of 26°C isotherm which
OMT collected during January–March can be used in

assessing whether the amount of rainfall in monsoon will be less or more than a certain long-term mean. Select the correct using the code given below:

Explanation

The correct option is 2 only. Ocean Mean Temperature (OMT) significantly influences atmospheric conditions and the monsoon patterns in South Asia. The temperature of ocean waters, particularly during the January–March period, can impact the intensity and volume of rainfall during the subsequent monsoon season, thus serving as a predictive indicator for rainfall deviations from long-term norms. This linkage highlights the interplay between oceanic thermal conditions and weather patterns, which is an essential aspect of climate science relevant to UPSC studies.
