Impact of southern annular mode on the Indian Ocean surface waves
Meenakshi, S.; Remya, P.G.; PraveenKumar, B.; Gangiredla, S.; Nair, T.M.B. (John Wiley & Sons, Ltd, 2023)Interannual climate modes, especially the southern annular mode (SAM), significantly influence the wave climate modulation of the Indian Ocean (IO). The present study, aligned with previous research, identifies two crucial ... -
Processes controlling the surface temperature signature of the Madden–Julian Oscillation in the thermocline ridge of the Indian Ocean
Jayakumar, A.; Vialard, J.; Lengaigne, M.; Gnanaseelan, C.; McCreary, J.P.; PraveenKumar, B. (Springer, 2011)During boreal winter, there is a prominent maximum of intraseasonal sea-surface temperature (SST) variability associated with the Madden–Julian Oscillation (MJO) along a Thermocline Ridge located in the southwestern Indian ... -
Processes of interannual mixed layer temperature variability in the thermocline ridge of the Indian Ocean
PraveenKumar, B.; Vialard, J.; Lengaigne, M.; Murty, V.S.N.; Foltz, G.R.; McPhaden, M.J.; Pous, S.; Montegut , C.deB. (Springer, 2014)Sea-surface temperature interannual anomalies (SSTAs) in the thermocline ridge of the southwestern tropical Indian Ocean (TRIO) have several well-documented climate impacts. In this paper, we explore the physical processes ... -
Seasonal mixed layer heat balance of the southwestern tropical Indian Ocean
Foltz, G.R.; Vialard, J.; PraveenKumar, B.; McPhaden, M.J. (American Meteorological Society, 2010)Sea surface temperature (SST) in the southwestern tropical Indian Ocean exerts a significant influence on global climate through its influence on the Indian summer monsoon and Northern Hemisphere atmospheric circulation. ... -
TropFlux wind stresses over the tropical oceans: Evaluation and comparison with other products
PraveenKumar, B.; Vialard, J.; Lengaigne, M.; Murty, V.S.N.; McPhaden, M.J.; Cronin, M.F.; Pinsard, F.; Reddy, K.G. (Springer, 2013)We present TropFlux wind stresses and evaluate them against observations along with other widely used daily air-sea momentum flux products (NCEP, NCEP2, ERA-I and QuikSCAT). TropFlux wind stresses are computed from the ... -
TropFlux: air-sea fluxes for the global tropical oceans-description and evaluation
PraveenKumar, B.; Vialard, J.; Lengaigne, M.; Murty, V.S.N.; McPhaden, M.J. (Springer-Verlag, 2012)This paper evaluates several timely, daily air-sea heat flux products (NCEP, NCEP2, ERA-Interim and OAFlux/ISCCP) against observations and present the newly developed TropFlux product. This new product uses bias-corrected ...
