I think winter is the most important season to the properties of the water in the permanent thermocline. In the tropics, winter cooling is not strong enough to destroy the seasonal thermocline, and a shallow feature sometimes called the tropical (permanent) thermocline is maintained throughout the year. 2. Look at Figure in slide 25, why are the meridional variations of temperature and salinity between stations A and D similar to the vertical variations of T & S from the surface down along the line A'B'C'D'. The principal factors are the combination of water mass formation and Ekman pumping. The subtropics are a region of negative curl( /f), which means thatpumping....
