|
| q | Jacob Bjerknes was the first one to |
||||||||||
| recognizes
that El Nino is not just an |
|||||||||||
| oceanic
phenomenon (in his 1969 |
|||||||||||
| paper). |
|||||||||||
| q | In stead, he hypothesized that the |
||||||||||
| warm
waters of El Nino and the |
|||||||||||
| pressure
seasaw of Walker’s Southern |
|||||||||||
| Oscillation
are part and parcel of the |
|||||||||||
| same
phenomenon: the ENSO. |
|||||||||||
| q | Bjerknes’s hypothesis of coupled |
||||||||||
| atmosphere-ocean
instability laid the |
|||||||||||
| foundation
for ENSO research. |
