El Nino
El Nino
Rainfall in the eastern Pacific is typically lower than in the western Pacific. The eastern Pacific tends to have a drier climate due to the presence of the cold California Current that limits moisture transport. In contrast, the western Pacific, near the equator, receives higher rainfall amounts due to the warmer ocean temperatures and greater atmospheric convection.
During La Nina, cooler-than-average sea surface temperatures in the central and eastern equatorial Pacific Ocean lead to changes in atmospheric circulation patterns. This can result in increased rainfall in the western Pacific and parts of the Americas, leading to wetter-than-normal conditions in some regions (such as Australia and Southeast Asia) and drier conditions in others (such as the southwestern United States). La Nina can also enhance hurricane activity in the Atlantic Ocean.
The water in the western Pacific is typically warmer than in the eastern Pacific because trade winds blow the warm waters of the eastern Pacific westward and keep it there. Also, upwelling in the eastern Pacific keeps the water cooler.The warmer water creates more clouds and rain, keeping Indonesia and other areas of the western Pacific wetter than Peru and other coastal regions of South America.During El Niño, the pressure gradient (rate of pressure change between areas of high and low pressure) weakens. In the western tropical Pacific, there is unusually high air pressure, while there is unusually low air pressure in the eastern tropical Pacific. This Southern Oscillation causes the trade winds to weaken, and even blow backwards. This pattern reversal leads to unusually wet weather in parts of South America, and unusually dry weather in the western Pacific.El Nino usually occurs every 3 to 7 years, and lasts for about 18 months.La Niña is the opposite of El Niño. These two weather patterns oscillate every few years.During La Niña, there is unusually low air pressure over the western tropical Pacific, and unusually high air pressure in the eastern tropical Pacific. The easterly blowing trade winds strengthen, blowing more warm water away from the equatorial Pacific. As a result, Australia and Indonesia become wetter than normal, and parts of South America become drier than normal.
The Great Divide is a hydrologic boundary defined by the ultimate destination of precipitation; rainfall on the western side of the Divide flows to the Pacific Ocean, while rainfall on the eastern side flows to the Gulf of Mexico.
the western part receives less rainfall and is higher in elevation
I Think that western ghats have very high rainfall but eastern stopes have not therefore western ghats have thick vegetation
Pacific
Most rainfall typically occurs on the western coast of continents, particularly in regions influenced by prevailing winds and ocean currents. The western coasts of continents, like the Pacific Northwest of the United States, often experience orographic lift, where moist air rises over mountains, leading to increased precipitation. In contrast, eastern coasts may have drier conditions, although this can vary based on specific geographic and climatic factors. Overall, the western coast tends to receive more consistent and abundant rainfall.
It depends on where you live. Western USA: Pacific Ocean Eastern USA: Atlantic Ocean
During El Niño events, the Pacific Ocean experiences warmer than average sea surface temperatures in the central and eastern tropical Pacific. This disrupts normal weather patterns, leading to increased rainfall in the eastern Pacific and drought conditions in the western Pacific. The changes in ocean temperatures also affect global atmospheric circulation patterns, influencing weather patterns around the world.
That would have to be the Atlantic and Pacific oceans.
