Seasonal Variability of Subthermocline Eddy Kinetic Energy East of the Philippines

چکیده
Abstract Seasonal modulation of subthermocline eddy kinetic energy (EKE) east the Philippines and its associated dynamics are studied, using mooring measurements outputs from an eddy-resolving ocean general circulation model for period 2000 to 2017. Significantly high EKE appears below thermocline in latitude band between 5° 14°N Philippines. Separated by 10°N, northern southern parts region shows nearly opposite seasonal cycles, with magnitude reaching a maximum early spring minimum summer part winter region. Further investigation indicates that both baroclinic barotropic instabilities essential generating eddies, but variation is mainly caused instability. The instability evolution North Equatorial Undercurrent Halmahera Eddy, respectively.

A mathematical connection is established between the ocean near-surface geostrophic kinetic energy and the small-scale variance of its surface height. The latter is defined as the spatial variance of sea surface height inside a given grid box and represents a basic statistical characteristic of the field, necessary for estimating its vulnerability to sampling error. The former is also computed ...

[1] The seasonal variation of eddy kinetic energy (EKE) of the North Pacific Subtropical Countercurrent (STCC) was investigated by analyzing the data from an eddy-resolving OGCM with the horizontal resolution 1/12 in comparison with satellite altimetry data. Although the annual cycle of simulated EKE of the whole STCC domain showed agreement with satellite data, with a maximum in spring and a m...
