Pune: Increased ocean waves in the Indian Ocean have had an impact on rainfall in the Indian Monsun, a study by the Indian Tropical Meteorology Institute (IITM), Pune, has been found.
This study, led by senior scientist IITM ROXY MATHEW KOLL, and published in JGR Oceans, found a significant increase in marine sea waves, assisted by fast heating in the Indian Ocean and the strong El Ninos.
“We found that sea sea waves have had an impact on the rainy season by reducing rainfall on the child of the Central Indian continent while increasing it on the South Peninsula, which can reach a certain extent explain the recent flood events in India,” Koll said.
The researchers told Ti that Heubwa the sea used to rarely occur in the tropical Indian Ocean, but now it has become an annual event.
“The West Indian Ocean region has experienced the largest increase in sea waves at a rate of around 1.5 events per decade, followed by the northern bay of Bengal at a rate of 0.5 events per decade.
During 1982-2018, West Indies Ocean has a total of 66 temporary events.
Bengal Bay has 94 events, “Koll said.
Experts also say that the word sea wave in the western Indian Ocean and Bay Bay have resulted in drying conditions for the Central Indian continental child.
At the same time, there was a significant increase in rainfall in India South Peninsular in response to heat waves in the northern bay of Bengal.
These changes in responding to sea wind modulation by Heubwave.
They said this was the first time a study had shown a close relationship between the sea Heatwa and the circulation of atmosphere and rainfall.
“The projection of the climate model shows further warming of the Indian Ocean in the future, which will most likely intensify the sea waves and its impact on the monsoon rainfall.
Because of the frequency, intensity, and areas covered by increased sea waves, we need to increase our marine observation array To monitor this event accurately, and update our weather model to predict the challenges presented by the warming world, “Koll said.
According to IUCN, the very warm water temperature in 2011 survived along the coastline of Western Australia caused coral bleaching, mass of sea life and destroying seaweed forests.
Since then, abnormal high water temperatures have been recorded in many regions.
Heublawa sea, according to climate scientists, is equivalent to underwater fire, and also with extreme weather events on land.
They have great consequences for sea biodiversity and ecosystems, fisheries and aquaculture industries.
IUCN’s study also said that seahave sea had increased by 50% over the past decade and now lasted longer and worse.
They can last for weeks or even years.
They can affect the small area of the coastline or stretch some oceans.
They have been recorded on the surface and deep waters, in all latitude, and in all types of marine ecosystems.
IUCN also said that when the sea waves became more frequent and extreme they risk pushing the ecosystem outside the threshold of their recovery; With eternal consequences for marine biodiversity, and millions of people whose livelihood depends on him.
