Which one of the following is not a resultant of the El Nino effect?
General KnowledgeGeography
- ADistortion of equatorial atmospheric circulation
- BFlow of the South-East Trade Winds towards the Indian Ocean
- CIrregularities in the evaporation of sea water
- DReduction in the amount of planktons which reduces the number of fish in the sea
Explanation
El Niño — abnormal warming of the eastern Pacific — distorts equatorial atmospheric circulation, alters sea-water evaporation, and suppresses upwelling, cutting plankton and fish off South America. It WEAKENS the trade winds rather than driving a ‘flow of the South-East Trade Winds towards the Indian Ocean’ — so B is not a resultant of El Niño.
