"One reason the South Asian monsoon is so strong is theres this big barrier to the north keeping the land warm, and theres an ocean to the south thats cooling, so its perfectly situated to be really strong," Lutsko added. But for the most part, the strength and timing of the monsoon, on which millions of farmers depend each year, is incredibly difficult to predict. But in our model, we had no such barrier, and we were still able to generate a monsoon, and we were excited about that," Lutsko said.Scientists have traditionally focused on the Himalayas as a key influencer of the South Asian monsoon.."We initially had a picture that we couldnt make a monsoon without the Himalayas, which was the established wisdom. When people got rid of them in simulations, there was no monsoon. But we feel we can explain this, using our minimal model," Lutsko concluded."
What we find is, the oceans response plays a huge role in modulating the intensity of the monsoon.Ultimately, researchers work may help to explain why the South Asian monsoon is one of the strongest monsoon systems in the world. But these models were run without an ocean," co-researcher Lutsko said.They say this ocean heat transporting mechanism may be a new knob in controlling the seasonal South Asian monsoon, as well as other monsoon systems around the world.As these winds drive northward, they also push ocean waters southward, much like a runner pushing against a treadmills belt. Understanding the oceans response is critical to predicting the monsoon," said one of the researchers, John Marshall. The results could help researchers predict how monsoons will change with warming oceans.Their China Industrial open timing belt Factory results show that as the summertime sun heats up the Indian subcontinent, it also kicks up strong winds that sweep across the Indian Ocean and up over the South Asian land mass."Whats interesting to me is, during times when the northern hemisphere was much colder, you see a collapse of the monsoon system.Washington: New research finds ocean activity may control the strength and intensity of summer monsoons."Before, people thought the Himalayas were necessary to have a monsoon system.Each summer, a climatic shift brings persistent wind and rain to much of Southeast Asia, in the form of a seasonal monsoon. The combination of the Himalayas to the north, which acts to warm up the land, and the ocean to the south, which takes heat away from nearby waters, sets up an extreme temperature gradient for one of the most intense, persistent monsoons on the planet.In future work, the researchers plan to apply their newfound observations of the oceans role to help interpret variations in monsoons much farther back in time.The researchers also found these south-flowing waters act to transport heat along with them, cooling the ocean and in effect increasing the temperature gradient between the land and sea. People dont know why that happens.
Its thought that the massive mountain ridge acts as a barrier against cold winds blowing in from the north, insulating the Indian subcontinent in a warm cocoon and enhancing the summertime temperature difference between the land and the ocean. The general cause of the monsoon is understood to be an increasing temperature difference between the warming land and the comparatively cool ocean.According to the study published in the Journal of Climate, the interplay between atmospheric winds and the ocean waters south of India has a major influence over the strength and timing of the South Asian monsoon.
