Near-equatorial trough

Since 1954, studies concluded that the near-equatorial trough was associated with a maximum in oceanic sea surface temperature. It is sometimes used as a synonym for the terms near equatorial tradewind convergence,[1] Intertropical convergence zone, and monsoon trough.[2] Surges of higher pressure from high latitudes can enhance tropical disturbances along its axis.[3] A pair of these troughs can occur during the Spring transition season.[4]
