Consider the anomalous conditions that accompany El Nino. Explain how two of these conditions are physically consistent with a reduced east-to-west (EW) pressure gradient. El Nino .Reduced EW pressure gradient. El Niño Conditions Disruption of Walker cell: Reduced trade winds below and westerlies above. Reduced equatorial upwelling and marine productivity. Weakening of equatorial cold tongue, i.e. warmer E-Pacific. Reduced thermocline and sea level 1 slopes. Upwelling water in the east is less cold and less nutrient rich Equator Thermocline Amerc Melecordegical Socety 80 w O The above changes in pressure, wind, sea level, and upwelling are physically consistent with each other.Explanation / Answer
ELNINO is also known as EL NINO southern oscillation (ENSO) is a naturally occuring phenomenon involves fluctuating of temperature in equatorial pacific. this temperature fluctuation mainly takes place between two states: warmer than normal central ans eastern equatorial pacific SSTs(EL NINO) and cooler than normal central and eastern equatorial pacific SSTs (LA NINO). sea surface temperature (SST) mainly used to identify this oscillation. the warm phase of ENSO cycle features warmer than normal SSTs across central and eastern equatorial pacific with
