The Cuban Countercurrent (CCC), along with the Yucatan Current, forms part of the Yucatan Basin circulation system, but it has not been well described and its connection to the system of currents in the Caribbean Sea has not been studied. Based on altimetry data (1993–2009) and the MERCATOR three-di...

| description | The Cuban Countercurrent (CCC), along with the Yucatan Current, forms part of the Yucatan Basin circulation system, but it has not been well described and its connection to the system of currents in the Caribbean Sea has not been studied. Based on altimetry data (1993–2009) and the MERCATOR three-dimensional assimilation model (2007–2009), the CCC was observed flowing ~1000 km from the eastern Yucatan Channel to Jamaica and to have a width of ~150 km. Off southern Cuba, the mean velocity was 0.20 m s–1 at the surface and 0.05 m s–1 at 1000 m depth. The CCC transported ~3.5 Sv when it passed through the Yucatan Channel towards the Caribbean Sea, where ~1.6 Sv was recorded south of Cuba. During its annual cycle, the CCC weakened from December to February (0–250 m) and in the summer its magnitude intensified slightly, reaching 0.35 m s–1 in August, due to the increase in water temperature of the Atlantic warm pool. Consequently, the sea level rose in the center of the Yucatan Basin and the pressure gradient increased along the Cuban coast, producing an increase in zonal velocity (0.1 m s–1) and transport (2–3 Sv; r = 0.90). Its connection to the Caribbean current system demonstrated the importance of its study.
La contracorriente Cubana (CCC), junto con la corriente de Yucatán, forma parte del sistema de circulación de la cuenca de Yucatán. Sin embargo, la CCC ha sido poco descrita y se desconoce su conexión con el sistema de corrientes del mar Caribe. Los datos altimétricos (1993–2009) y del modelo tridimensional de asimilación MERCATOR (2007–2009) permitieron observar que la CCC recorrió ~1000 km desde el este del canal de Yucatán hasta Jamaica y tenía un ancho de ~150 km. Al sur de Cuba, la velocidad promedio fue de 0.20 m s–1 en la superficie y de 0.05 m s–1 a 1000 m de profundidad. La CCC transportó ~3.5 Sv cuando pasó por el canal de Yucatán en dirección hacia el mar Caribe, donde se registró un transporte de ~1.6 Sv al sur de Cuba. En el ciclo anual, la CCC se debilitó de diciembre a febrero en la superficie (0–250 m) y en el verano su magnitud se intensificó ligeramente hasta 0.35 m s–1 en agosto, debido al aumento en la temperatura de la alberca de agua cálida del Atlántico. Como consecuencia, el nivel del mar aumentó en el centro de la cuenca de Yucatán y se incrementó el gradiente de presión a lo largo de la costa de Cuba, lo cual produjo un incremento en la velocidad zonal (0.1 m s–1) y el transporte (2–3 Sv; r = 0.90). La conexión de la CCC con el sistema de corrientes del mar Caribe demostró la importancia de su estudió. |
