Use the controls below to increase and decrease speed and width of wave movement on the map.

In certain areas and times, waves may be at low speed. By increasing the speed and increasing the width, it is possible to better observe some phenomenons.


Use the control below to increase or decrease the player's loop time.


If it is on, at each zoom in or out, the system will increase or decrease the amount of displayed flows.

REMO

The Oceanographic Observation and Modeling Network (REMO) is a Brazilian effort in physical oceanography and operational oceanography conducted by a group of researchers, technicians and students associated with universities, research centers and the Brazilian Navy, funded by Petrobras and the National Agency of Petroleum, Natural Gas and Biofuels ( ANP).

The overall goal of REMO is the development of science and technology in physical oceanography, ocean modeling, observational oceanography and operational oceanography with data assimilation.

Modelo Wavewatch III™

Wavewatch III™ is a community wave model developed at the National Weather Service (NWS) / National Oceanic and Atmospheric Administration (NOAA) that includes significant improvements compared to its predecessors (WWI and WWII) regarding the governing equations, model structure, numerical methods, and physical parameterizations. The model calculates the evolution of the two-dimensional wave spectrum through the action density balance equation. The source term is typically represented as a sum of three processes: wind input energy, nonlinear wave-wave interactions, and dissipation due to whitecapping. The model's physics includes energy generation, wave-breaking-induced dissipation, bottom friction, refraction, advection, and quadruplet and triplet wave-wave interactions.

WW3 at CHM

Currently, the Hydrography Center of the Navy (Centro de Hidrografia da Marinha) runs version 6.07 of WW3 with the source term for input/dissipation as ST4 (Ardhuin et al., 2010). Operationally, WW3 runs globally using atmospheric forcings from the American GFS/NOAA model and the German ICON/DWD model. The global runs provide inputs for other areas, such as Antarctica and METAREA V. The Antarctica region utilizes 10-meter wind fields from ICON and GFS. METAREA V has three wave runs forced by the GFS, ICON, and COSMO models.
