The El Nino effect is a weather phenomenon that occurs in the Pacific Ocean. It is characterized by the warming of sea surface temperatures in the central and eastern equatorial Pacific Ocean, which can have significant impacts on weather patterns around the world.

Option 1 states that one of the results of the El Nino effect is the distortion of equatorial atmospheric circulation. This is correct, as El Nino can cause changes in the wind patterns and atmospheric pressure, leading to disruptions in the normal circulation of air.

Option 2 states that the flow of the South-East Trade Winds towards the Indian Ocean is not a resultant of the El Nino effect. This is correct, as during El Nino, the trade winds weaken or change direction, resulting in less of a flow towards the Indian Ocean.

Option 3 states that irregularities in the evaporation of sea water are a resultant of the El Nino effect. This is correct, as higher sea surface temperatures can result in increased evaporation, leading to changes in rainfall patterns and drought conditions.

Option 4 states that the reduction in the amount of planktons, which reduces the number of fish in the sea, is a resultant of the El Nino effect. This is correct, as the changes in ocean conditions due to El
