El Nino is the name of warm ocean current that affects weather of the Pacific Ocean. The diagrams compare the normal conditions in the Pacific with El Nino Conditions v.2

El Nino is a warm ocean current that affects the climate in Australia and Peru. Overall, the two diagrams illustrate the differences between El Nino compare to normal weather patterns. Under normal conditions, strong trade winds blow from the Eastern Pacific, pushing both storm clouds and warm water westwards while the weak opposing winds blow from the Western Pacific. Therefore, the weather in Australia is rainy, which provides an abundant supply of water for local vegetation. Although the weather in Peru is sunny, the cool and nutrient-rich water under the thermocline is elevated to the ocean surface on the West Coast of South America, increasing the marine life population in Peru. Under El Nino conditions, the eastern trade winds weaken while the eastward-blowing winds become stronger. Consequently, the warm, nutrient-poor water and storm clouds flow direction is reversed, blocking the cool water from rising up. A similar pattern can be seen for climates on both sides of the Pacific Ocean which negatively impact living organisms, excessive sunlight without rain killing plant life in Australia, whereas in Peru, fisheries decreased due to the lack of essential nutrients in the water.
