Q. Consider the following statements::
1.Dateline El Nino is a type of El Nino event where the warming of sea surface temperatures occurs primarily in the central equatorial Pacific region near the International Date Line.
2.A canonical El Nino often leads to above-average rainfall in the western Pacific region, including parts of Southeast Asia and Australia, while leading to a below-average rainfall along the western coast of South America, particularly in Peru and Ecuador.
3.Canonical El Nino and Dateline El Nino both are part of the El Nino-Southern Oscillation (ENSO) climate pattern.
How many of the above statements are correct?
Answer: B
Notes:
Explanation –
Statements 1 and 3 are correct. Dateline El Nino is a type of El Nino event where the warming of sea surface temperatures occurs primarily in the central equatorial Pacific region near the International Date Line. Canonical El Nino and Dateline El Nino both are part of the El Niño-Southern Oscillation (ENSO) climate pattern.
Statement 2 is incorrect. A canonical El Nino often leads to below-average rainfall in the western Pacific region, including parts of Southeast Asia and Australia, while increasing rainfall along the western coast of South America, particularly in Peru and Ecuador. Canonical El Nino is the traditional El Nino which usually happens.
