Equatorial Circulation and Dynamics, Tropical Geostropic Flows, El Nino/La…

- - - - Indian Ocean ones are not (mostly on the southern hemisphere
        
        Transient behavior
- - - - Trade winds: winds pushes water from the east to the west (hence the warm pool in the western pacific then upwelling in the eastern pacific)
- - - - Flow slightly away from the quator (more than a quarter degrees latituded
        
        Coriolis becomes important
- - - - high convection
        
        Upwelling in the cold tongue
        
        Below the ocean - shoaling
        
        Thinning of the thermocline hence mainit parin ?
- - - - Why is there divergence?
        
        Ekman transport (ekman current if on the surface)
        Due to the wind
        
        Westerlies + trade winds = convergence
        
        instantaneious
  - - - High to low
    - - hights show convergence
- - - - ekman pumping going down
- - - - Manifests from the wind as it weakens
    - - sea surface height
- - - - less nutrients
        
        nutrient depated
- - - - el nino hase westerly wind anomalies in western equatorial pacific
- - - - upwells cold to surface
    - - in warm pool
        
        upwells warm to surface so does not result in cold surface water
        
        nutrient not rich
