The depth of the 26\u00b0C isotherm is not fixed at 129 meters but varies geographically and seasonally. While it might be around 129 meters in the specific region (south-western Indian Ocean) and time (January-March) mentioned, stating it as a fixed depth &#8220;which is 129 meters&#8221; can be misleading, as the OMT is defined by the varying depth of the isotherm, not a fixed depth. Therefore, this statement is likely inaccurate or too specific\/poorly phrased for a general description.<br \/>\n2.  **Monsoon Prediction:** Studies have shown a strong correlation between the Ocean Mean Temperature in the southeastern equatorial Indian Ocean and the southwestern Bay of Bengal during the pre-monsoon period (January-March or April-May) and the subsequent Indian Summer Monsoon rainfall. Higher OMT in this region is generally associated with a better monsoon.
