PUNE:

Mahabaleshwar

has been wetter than Mawsynram, the wettest place on Earth, this

.

The hill station in

received 7,175.4mm rain as against Mawsynram's 6,218.4mm from June 1 to September 4, data with the

(IMD) shows. Cherrapunji received around 6,082.7mm rainfall in the same period.

Tourists to Mahabaleshwar said they have witnessed blinding rain. The hill station outperformed Cherrapunji, the second wettest place in the world, last year.

Mahabaleshwar received 194mm rainfall in the 24-hour period from September 4 to 5, bringing its tally to 7,369.4mm. The same 24-hour period count for Mawsynram was not available. Mahabaleshwar received extra rainfall of over 2,000mm this monsoon.

Mahabaleshwar’s rain count trumps that in wettest spot in the world

Mawsynram, in the East Khasi hills of Meghalaya, has only seen double digit or lesser rainfall in the last few days. Though its normal June-August rainfall is over 8,233.5mm, it received 6,167mm during this period this monsoon, much below its normal.

Pulak Guhathakurta, head of the climate application and user interface, Climate Research and Services, IMD Pune, told TOI that during this monsoon, especially since June-end, all of Konkan and most of Madhya Maharashtra received much higher rainfall than normal.

“Mahabaleshwar is the only station in Madhya Maharashtra that normally receives very high rain during the monsoon because of its orography. It has a unique geographical location in the rain-battered region of the Western Ghats,” he said.

The ghats receive heavy rainfall during monsoon. “Though this happens every year, this time the westerly winds from the Arabian Sea were strong. The moisture content in the winds was also huge due to several weather conditions, including the monsoon lows, unique position of the upper air cyclonic circulation and the offshore trough. Hence, there was heavy rain in the windward side of the Western Ghats and the ghat regions,” Guhathakurta said.

Torrential rains in Mawsynram and Cherrapunji are common. Both are located in a funnel-shaped region formed by the Khasi, Garo and Jaintia hills.

The two locations, 81km apart, receive rain from the Bay of Bengal branch. The clouds travel over the plains of Bangladesh for hundreds of kilometres and collide with the Khasi hills.

“The hills have numerous deep valleys and channels. Strong winds push these clouds through the deep valleys and lift them up. The upward motion helps water vapour condense, increasing the moisture content in the winds. When these winds saturated with moisture collide with the Khasi hills, extremely heavy rain occurs over the windward side, where Mawsynram and Cherrapunji are located,” Guhathakurta said.

Link to climate change

Patharpunj in Patan taluka in Satara has also recorded 7,000mm rainfall during this monsoon, J R Kulkarni, chairman of the India Meteorological Society, Pune Chapter (IMSP), told TOI.

“Such extreme events can be partly attributed to climate change and global warming. Because of the increase in temperature, the moistureholding capacity of the atmosphere increases. If there is a one-degree increase in temperature, the moisture holding capacity of the atmosphere increases much more. Hence, regions already prone to high rainfall get much higher amounts,” he added.
