Global Mapping of Near-inertial and Tidal Internal Wave Propagation
Abstract
The long-term goal is to understand the magnitude and distribution of internal-wave propagation and internal-wave- induced mixing. Objectives: To use detect energy-flux associated with low-mode near-inertial and tidal propagation in moored current meter data at as many locations as possible. To determine the degree to which energy-flux divergences (and therefore sites of enhanced dissipation) can be determined from this analysis. To compute time-averaged spatial maps of near-inertial, internal-tidal and mesoscale energy from TOPEX/ POSEIDON altimetry, drifters, current meters and ADCP tracks. To determine, within the context of Peter Muller's Internal Wave Action Model (IWAM, also supported by ONR), the extent to which these findings are consistent with existing internal-wave propagation theories. To use large-scale and regional atmospheric models to examine the high-latitude and small-scale reliability, interannual variability, and convergences/divergences in the wind energy flux maps computed by Alford (2001, 2003).
