With reference to Ocean Mean Temperature (OMT), which of the following statements is/are correct?
1. OMT is measured up to a depth of 26°C isotherm which is 129 meters in the south-western Indian Ocean during January – March.
2. 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 answer using the code given below:
1 only
2 only
Both 1 and 2
Neither 1 nor 2
Solution
Mean 26°C isotherm depth in SW Indian Ocean during Jan-Mar is around 59 metres, not 129 (1 wrong). OMT during Jan-Mar reliably predicts monsoon rainfall (better than SST) — 2 correct. Answer: (b).
