- Cross Hemispheric Influence on ISs
Summary
- Decadal warming of W. Antarctic surface
= coincident with Equatorial Pacific heating due to ENSO
- Causative link between 2 connected by Rossby wave train
--> leads to high pressure over Amundsen/Bellinshausen
- Effect = very sensitive to location of equatorial heating

-
What mechanism relates?
- Strengthened Equatorial heating & SSTs in Pacific
- Increased air surface pressure in Antarctica
-
-
Rossby
Wave How?
- Low pressure centre @ Equator
induces cyclonic circulation just S. of it
