Understanding El Niño: Ocean Currents, Thermocline, and Their Global Impacts

This feature delves into the intricate dynamics of El Niño, highlighting key phenomena like ocean currents and the thermocline. We explore how these elements interact, with the current moving east and the thermocline occurring deeper in the eastern Pacific Ocean. It discusses convection and the potential for upwelling to be disrupted. Additionally, we analyze the reverse of normal circulation and how the warm pool spreads eastward when trade winds weaken. Part 2 focuses on the broader impacts of El Niño and La Niña events on global weather patterns.

  1. Match up Numbers With Letters Feature __ is .. during an El Niño.    1. an ocean current……..     It moves to the east     2. the thermocline. …….    It occurs deeper in the eastern Pacific Ocean     3. convection……. It forms further east    4. upwelling. ……It may get "shut off" by the layer of warm water above     5. normal circulation……… The surface winds (trade winds) may reverse    6. the warm pool……... It starts to spread eastward when the trade winds slacken Part 2- discuss the impacts of El Nino and La Nina (8)
