Pune: Rainfall was reported every month after the monsoon season got over last year till June this year. Meteorologists attributed this changing pattern to climate change.
According to the climate experts, the monsoon season extends till September. However, every month has recorded some or other form of rainfall in Pune and Maharashtra since September last year till June this year.
Speaking to Sakal Times, senior agri-meteorologist and former head of department (HOD) of the weather department of the Agriculture College, Ramchandra Sabale said the increase in rainfall activity and more cyclones are the result of changing climate.
“Rainfall in every month even after the monsoon season was over indicates that this year was different. Also, the normal average temperature has increased in the past few years. The reason behind these changes is global warming and climate change. Due to a rise in temperature, the air pressure reduces and the cloud formation is seen. “So, there is rain every month. Cyclone and depression activities are also seen to have increased in the last couple of years. All of this is due to increasing temperature that is because of climate change,” said Sabale.
Sharing Sabale’s view, Mahesh Palawat, vice-president, Meteorology and Climate Change with Skymet, a private weather forecaster, told Sakal Times that the frequency of weather activities for last year’s monsoon has been more.
“Usually we see that Bay of Bengal develops more weather systems. But this time, we have seen that due to warming of south Arabian sea, there has been more weather systems that were developed in this region. They later travelled towards north Arabian sea and caused rainfall in parts of Karnataka and Maharashtra,” said Palawat.
He added since September last year, the west coast had witnessed rainfall activity in December as well due to the Ockhi cyclone.
“The increase in cyclone and depression activities has been observed. They result in unseasonal rainfall. Recently, Arabian sea witnessed cyclone Sagar and cyclone Mekunu, which affected Oman a lot. But the depression initially developed in the south Arabian sea,” said Palawat.
