1. OMT is measured up to a depth of 26°C isotherm which is 129 meters in the southwestern Indian Ocean during January — March.
2. OMT collected during January — March can be used in assessing whether the amount of rainfall in the monsoon will be less or more than a certain long-term mean.
Select the correct answer using the code given below:
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
5. Ans: b
Explanation:
Distribution of Temperature in Oceans
The distribution of temperature can be ocean mean temperature, Horizontal Distribution of Temperature and Vertical Distribution of Temperature.
Ocean Mean Temperature
- Ocean Mean Temperature (OMT) is measured up to a depth of 26 degrees’ isotherm. During January–March, the mean 260C isotherm depth in the Southwestern Indian Ocean is 59 metres.
- It is measured with the help of satellites that orbit the earth. In the Indian Ocean, OMT is analaysed by measuring the ocean thermal energy during the period from January to March.
Hence, statement 1 is incorrect & statement 2 is correct.
