dc.description.abstractThis study focuses on the Amazon ISWs occurrence, their velocity/wavelength, and variability at seasonal cycles. The analysis is based on a data set composed of 71 MODIS/TERRA images, where more than 250 internal solitary wave (ISW) signatures were identified in the sun glint area. ISWs packets separated by typical mode-1 and mode-2 internal tides (ITs) wavelengths have been identified and mapped coming from sites A, and B. In area B, the mode-1 and mode-2 ISWs seem to have lower wavelengths than the ones in area A. Mode-1 ISWs from site A showed higher wave velocity/wavelength during the boreal summer/fall, with higher diversity in terms of propagation velocities. Calculations of the IT velocities using the Taylor-Goldstein equation supported our results of shorter-scale ISWs associated with mode-2 IT wavelengths in the study area and additionally into the ISW/IT seasonal variability.eng
