The leading edge of a tropical instability wave : interpretation as a gravity current

Creator:

McHugh, Elizabeth Helen

Abstract:

A sharp temperature front, oriented along the south-west corner of the leading edge of a Tropical Instability Wave (TIW) warm trough, was encountered at 0°N, 140°W on November 2, 2008 and detected by a 0.45°C increase in SST that occurred over 7 s. The distinct SST signal was observed at...

Masters Thesis
The cross-equatorial structure of tropical instability waves in sea surface height

Creator:

Lyman, John M.

Abstract:

A linearized model with two vertical modes has been developed to understand observed characteristics of monthly variability in the Equatorial Pacific from TOPEX/POSEIDON measurements of Sea Surface Height (SSH). The 2-mode model is obtained from an equatorial beta plane model that has been linearized about a geostrophically balanced mean flow...
