What is the predominant time for the Afternoon Effect in the Equatorial region?

The predominant time for the Afternoon Effect in the Equatorial region is between 1400-1500 local time. This phenomenon is characterized by variations that typically arise in oceanographic and acoustic measurements due to changes in environmental conditions such as temperature and atmospheric pressure.

During the period of 1400-1500L, the sun's intensity is at its peak for the day. This increase in solar heating can significantly influence the upper layers of the ocean, leading to changes in thermocline depth and temperature profiles, which affect sound propagation characteristics. As a result, observations and acoustic conditions during this timeframe are crucial for accurate data collection and interpretation in this specific region.

Other time periods listed do not align as closely with the peak solar heating and its effects on the ocean environment, which are essential for understanding the Afternoon Effect's timing and impact on measurements. Understanding this context is vital for effectively utilizing acoustic data in oceanographic studies.
