  abstract = {{T}wo major findings of this study are i) the presence of a robust intraseasonal oscillation ({ISO}) signal in the {B}ay of {B}engal ({BOB}) subsurface ocean heat content ({OHC}) anomaly, this {ISO} signal propagates northward at the rate of roughly one degree latitude per day and ii) a lag of roughly 4 to 6 days between the appearance of this signal in the surface wind speed and followed by the {OHC} anomaly. {T}he availability of long-term daily data sets for the {OHC} made it possible to examine the presence of {ISO} over the {BOB}. {T}his study also examines the possible relationship of {ISO} signal in the {OHC} with other parameters, such as surface wind (wind speed, wind stress curl and related upwelling/downwelling), sea surface temperature ({SST}), net surface heat flux into the ocean and surface rain. {T}his study confirms the finding of a robust signal for the {OHC} anomaly over the {B}o{B}, on the time scale of {ISO}, using daily data sets for a 17 years period covering each of the summer monsoon seasons. {A}lso included is an analysis of rainfall and river runoff variability over north of the {B}o{B}. {T}he river runoff and the precipitation data sets also show a robust {ISO} time scale. {T}he mutual relationships among precipitation, {SST}, net heat flux and {OHC} are also examined in this study. {T}his work addresses the lag relationship between the surface wind speed and the {OHC}, a lag of roughly 4 days relates to strong winds impacting a cooling of the ocean. {T}he ranges of spread of all the above parameters for the total field and for the {ISO} time scale are expressed as percentage variability of the {ISO} time scale. {T}hose show that the {OHC} anomaly over the {B}ay of {B}engal is quite a robust feature. {T}his study does not address modeling issues.},
