Question

Answer in at least one paragraph for each question.

1. Explain why the northern surface currents in the Indian Ocean change direction seasonally.

2. What is El Niño? How does it form and what are the results?

Answer 1

1) the northern surface currents in the Indian ocean change direction seasonally in response to the seasonal movement of the monsoon . These currents seasonally reverses with the wind system . The direction is changed because of the reversal of sinds associated with winter and the summer monsoon . In summer time , the land is warmer than the ocean and due to this the surface winds move to the land from the ocean .

2) El Nino is a climate cycle of the Pacific Ocean with a global impact on the patterns of the weather . It occurs in the sea surface temperature in Pacific Ocean . The temperature rises more than the normal temperature for some period of time .

El Nino is formed when the interaction between the surface layers of Pacific Ocean and the atmosphere over it takes place . Due to El Nino the surface water temperature increases to some extent . The rainstorms and the clouds do also shifts towards east due to the increasing temperature of the surface layers . This El Nino can cause health problems like malnutrition , respiratory diseases and many more .
