Will Kollur cross the 10000 mm rainfall mark in 2011 - List of places other than Cherrapunji & Mawsynram which has achieved the feat is given below

As i was wondering whether Kollur which is having a amazing run of rainfall 4452 mm (from 01.06.2011 to 21.07.2011 - 51 days) from others places in 2011 is an one off event, whether there are other places which has got Extraordinary Rainfall (10000 mms in a year) previously. I have excluded Cherrapunji and Mawsynarm from the list since its routine for them to achieve 10000 mm every year . Mostly the data were only available upto the year 1970. Kindly provide me other instances where it has crossed 10000 mm/year

1. KOTTIGEHARA (KARNATAKA)

• 1961 - 11363 mm (This includes an mind boggling 3046 mm rainfall in 11 days starting from July 1st to July 12. During July, 1961 Kottigehra got 5776 mm rainfall in one month)

2. HULIKAL (KARNATAKA)

• 1959 - 12137 mm (During July, 1959 Hulikal got 5027 mm rainfall in one month)

• 1961 - 12720 mm (During July, 1961 Hulikal got 4234 mm rainfall in one month)

3. AGUMBE (KARNATAKA)

• 1961 - 10527 mm (During July, 1961 Agumbe got 3592 mm rainfall in one month)

4. MATHERAN (MAHARASHTRA)

• 1921 - 10294 mm (Starting from July 22 to August 21, Matheran got 5693 mm in one month. This includes 485.9 mm on July 23 and followed by 657.4 mm on July 24)

5. SHIRALI (KARNATAKA)

• 1976 - 10316 mm (During July, 1976 Shirali got 4206 mm rainfall in one month)

• 1978 -11381 mm (During June 1978 Shirali got 4439 mm rainfall in one month)

• 1980 - 11180 mm (During June 1980 Shirali got 3779 mm rainfall in one month)

• 1981 - 11477 mm (During June 1981 Shirali got 4121 mm rainfall in one month)

6. BUXADUAR (WEST BENGAL)

• 1921 - 10004 mm (During July, 1921 Buxaduari got 3267 mm rainfall in one month)

6. MAHABALESHWAR (MAHARASHTRA)

• 1896 - 10221 mm

Other places such as Amboli, Vythri, Maya Bandar (9720 mm in 1980), Quilandy, Gaganbawada, Bhagamandala, have got between (8000-10000 mm) rainfall occasionally

Why Cherrapunji can not beat Kollur this year in South West Monsoon Rainfall

As you can the see the graphs of heavy rainfall places from various zones of the country.

1. North - Dharamshala
2. South - Agumbe
3. East - Cherrapunji & Passighat
4. West - Mahabelshwar

Cherrapunji gets its maximum rains from June to August, beyond that the rainfall decreases drastically. When comparing it to the rains of Southern giant Agumbe the pattern is similar Cherrapunji beats Agumbe by 500 mm in June and by 350 mm in July. The tables are turned in August where Agumbe gets whopping 750 mm more rainfall than Cherrapunji.

SWM Rainfall in mm as on 20.07.2011 (50 days) (min 2750 mm)

1. Kollur (Karnataka) - 4332
2. Dajipur (Maharashtra) - 3780
3. Sangameshwar (Maharashtra) - 3557
4. Agumbe (Karnataka) - 3523
5. Gaganbawada (Maharashtra) - 3519
6. Kitwade (Maharashtra) - 3213
7. Cherrapunji (Meghlaya) - 3020
8. Kadra (Karnataka) - 3000
9. Soliwade (Maharashtra) - 2855
10. Quepem (Goa) - 2805
11. Mahabaleshwar (Maharashtra) - 2768
12. Siddapura (Karnataka) - 2750

Considering this Kollur which also has similar rainfall of Agumbe. The difference between Kollur and Cherrapunji is 1300 mm even if both get their average rainfall in August. The lead is going to extend further only.

Even Gaganbawada and Sangameshwar which get good rains in August will have good chance to beat Cherrapunji this year in the SWM.

Agumbe has got 879 mm rainfall in last 4 days

The following are the rainfall recorded by Agumbe, Karnataka in the last 4 days

16.07.2011 - 153 mm
17.07.2011 - 336 mm
18.07.2011 - 220 mm
19.07.2011 - 170 mm

Total rainfall Agumbe got this season (01.06.2011 to 19.07.2011 - 49 days) is 3428 mm and is now second behind Kollur, Karnataka which has got 4221 mm rainfall in the race to be the wettest place this monsoon in India. Gaganbawada, Maharashtra till yesterday has got 3320 mm, lets see the rainfall today it has to get 11 cm to overthrow Agumbe from second position.

Kollur crosses 4000 mm rainfall in style & Cherrapunji falls further down the list.

The race to be the wettest place in India is something new because Its always been Cherrapunji always as Mawsynarm, Hulikal and Amboli are not readily available.

Rainfall in mm (01.06.2011 to 18.07.2011 - 48 days)

1. Kollur, Karnataka - 4111
2. Gaganbawada, Maharashtra - 3320
3. Agumbe, Karnataka - 3258
4. Sangameshwar, Maharashtra - 3007
5. Kadra, Karnataka - 2885
6. Cherrapunji, Meghalaya - 2828
7. Quepem, Goa - 2765

Quepem rainfall data not available for one day when Goa got battered 17.07.2011. I think it would have also crossed Cherrapunji's tally.


The break up of Kollur Rainfall are as follows -

1. 1000 mm - 15 days
2. 2000 mm - 28 days (13 days for the 1000 mm)
3. 3000 mm - 36 days (6 days for the 1000 mm)
4. 4000 mm - 48 days (12 days for the 1000 mm)
5. 5000 mm - ???? (I predict it will be less than 12 days)
   

Agumbe has got 686 mm rainfall in last 4 days

As expected the monsoon is been merciless in West Coast. The following are the rainfall recorded by Agumbe in last 4 days

14.07.2011 - 91 mm
15.07.2011 - 106 mm
16.07.2011 - 153 mm
17.07.2011 - 336 mm

Total rainfall it has got from this season (01.06.2011 to 17.07.2011 - 47 days) is 3038 mm till today and is now second behind Kollur in the race to be the wettest place this monsoon in India.

Rajesh, why is that this swm the west coast is getting copious rainfall than their average.

Quepem too got pounded with 715 mm rainfall in last 4 days

Complete Goa expect their capital is getting battered this season. This is the rainfall Quepem got in the last 4 days

13.07.2011 – 320 mm
14.07.2011 – 150 mm
15.07.2011 – 70 mm
16.07.2011 – 175 mm

Total rainfall it has got from this season (01.06.2011 to 16.07.2011 – 46 days) is 2685 mm.

Waiting for today's data, heared its raining very heavily there

Kollur still leads the rainfall table ahead of Cherrapunji

The most important thing about Kollur (Karnataka) rainfall is that it has got above 1cm rainfall from the day monsoon set in. It has got above 10 cm rainfall for 13 days and between 7-10 cm rainfall for 11 days.

The stars of Maharashtra, Gaganbawada is nearing Cherrapunji which has got (-1335 mm) rainfall less than the average. While Sangameshwar has gone above Agumbe which has got (-399 mm) rainfall less than the average and Kadra is also in striking distance of overtaking Agumbe, which has lost the Cherrapunji of South title to Hulikal, which is also located in Karnataka.

Top 5 SWM from 01.06.11 to 12.07.2011 (43 days)

1. Kollur, Karnataka - 3424 mm
2. Cherrapunji, Meghyala - 2607 mm
3. Gaganbawada, Maharashtra - 2447 mm
4. Sangameshwar, Maharashtra - 2322 mm
5. Agumbe, Karnataka - 2302 mm
6. Kadra, Karnataka - 2220 mm

The lead between Kollur and Cherrapunji is extending day by day. Its now at 817 mm.

Kollur cross 3000 mm rainfall in 35 days this monsoon

It has got above 10 cm rainfall 12 days out of total 37 days and between 8-10 cm rainfall for 6 days.

Top 5 SWM from 01.06.11 to 07.07.2011 (37 days)

1. Kollur, Karnataka - 3104 mm
2. Cherrapunji, Meghyala - 2363 mm
3. Gaganbawada, Maharashtra - 2256 mm
4. Agumbe, Karnataka - 2145 mm
5. Sangameshwar, Maharashtra - 2102 mm
6. Kadra, Karnataka - 2070 mm

The lead between Kollur and Cherrapunji is extending day by day. It would be nice to have data of Hulikal and Amboli

Hulikal is getting wetter than Agumbe - may now claim the title of ‘Cherrapunji of South’

Hulikal in Hosanagar taluk could be the new Agumbe, known as Cherrapunji of South India. (Left in pic Hulikal Falls)

In terms of annual rainfall over the last few years, Hulikal is far ahead of Agumbe. According to the statistics of the last five years, Hulikal has recorded more rain than Agumbe except in 2008.

Environmentalists and forest officials of the region feel deforestation in Tirthahalli taluk is the major cause for the decline in rainfall. Another contributory factor is the increase in area of monoculture forest at the cost of natural flora in various parts of the taluk.

Speaking to Deccan Herald, Prof B M Kumaraswamy, member of Western Ghats Task Force, said planting of acacia, eucalyptus and other trees at the cost of natural forest in various parts of Tirthahalli taluk by the Mysore Paper Mill (MPM) has had disastrous effect on rainfall in Agumbe.

‘Green deserts’

“Monoculture tree plantations are ‘green deserts’ that bring no rainfall. They can never be considered as forests. There is a need to create awareness among people about the adverse effects of monoculture tree plantations on bio-diversity and climate change,” Kumaraswamy said. According to the recent studies, such plantations would pave way for the loss of biodiversity and increase in emission of carbon due to degradation of the previous ecosystem and disturbance of soil.

Realising the negative impact on biodiversity, the Forest Department has now banned plantation of trees such as acacia, eucalyptus on forest land. Raveesh, a resident of Agumbe told Deccan Herald that besides deforestation, there were other scientific reasons for the decline in rainfall. The temperature in the region is rising by the year, resulting in Agumbe losing its cool climate.

Venkatesan, Deputy Conservator of Forests, said: “I feel the MPM should not have been allowed to take up monoculture tree plantation in a place like Tirthahalli where you have natural forest.” A resident of Tirthahalli has approached the Karnataka High Court against the tree plantation taken up by MPM. A committee has been formed to submit the report on the impact of such plantation on bio diversity.

Below normal monsoon in last 30 days in Southern peninsula

The dry phase from a passing Madden-Julian Oscillation (MJO) has ended. In the wet phase we can see how it helps the interior parts of the southern peninsula and also North East India. As on 27th June the mighty Cherrapunji (Annual 12000 mm) has got only 1101 mm which is below normal by 1396 mm. The same can be said for Passighat (Annual 4300 mm) which has got only 292 which is below normal by 463 mm. Shirali (Annual 4100 mm)in Karnataka has got only 934 mm which is below normal by 285 mm. Coochbehar (Annual 3400 mm) in West Bengal has got 376 mm which is below normal by 271 mm. Same way Buxa, Maheran have also got below normal rains.


In Tamilnadu except Chennai all district are having deficient rainfall.

The same is throughout Southern India. I have done a analysis and you can yourself see the results for the rainfall in last 30 days

Chennai receives 72mm rainfall in 1 hour

Rain takes Chennai by surprise. Receives 72mm in less than a hour

— Photo: K. Pichumani.

SURREALISTIC LOOK: A slice of the rain-soaked city on Monday.

Heavy rain that lasted over an hour caught people unawares in many parts of the city and suburbs on Monday evening.

The Meteorological Department in Nungambakkam registered 70.2 mm of rainfall during the 12-hour period ending 8.30 p.m. This is much mor e than the monthly average of 53.7 mm. Meenambakkam recorded 46 mm of rainfall during the same period. The sharp showers came after a sultry day as Nungambakkam and Meenambakkam recorded a maximum temperature of 38.4 degree Celsius and 38.8 degree Celsius, one degree above the average temperature this month. Several localities in and around the city, including Aminjikarai, Anna Nagar, T.Nagar, Koyambedu and Pallikaranai, experienced heavy showers accompanied by loud thunder. Some interior roads, including Arunachala Naicken Street at Chintadripet, were flooded. Besides affecting the traffic on arterial roads, many bus services were also hit.

The scattered materials near the Metro Rail project site at Kathipara junction following rains aggravated the traffic snarl on the stretch. Traffic was thrown out of gear for a couple of hours around Guindy and Saidapet with vehicles piling up for prolonged period of time. Murky sky and heavy showers around 7 p.m. took motorists by surprise and many of them took shelter under trees and shops. V.S. Rajkumar, a resident of Nerkundram, said “I had to wait at a teashop for almost 20 minutes until the rain subsided.” Residents of southern suburbs such as Medavakkam, Perungudi, Sholinganallur and Velachery complained of power cut for almost an hour.

Officials of the Meteorological Department said heavy downpour within an hour was caused by thunderstorm activity. However, such rainfall in June was not unusual. Last year, 53.4 mm of rain was registered in 24 hour period on June 28.

The highest recorded rainfall in a single day was 347.9 mm on June 14, 1996. (Which was accompanied by Tropical Storm) The department forecasts that the rain or thundershower would occur in some areas of the city and the maximum temperature would be 39 degree Celsius.
