Monsoon set for revival as Bay wakes up
The South-West monsoon is set for a revival of sorts after an intervening ‘break' phase, with an upper air cyclonic circulation springing up over north-west Bay of Bengal on Monday.
The circulation has helped the eastern end of the all-important land-based monsoon trough across northwest-to-southeast India to revert back to its normal position.
NORTHERN END
The northern end is expected to follow suit within the next two days bringing the rain cover to extend over west-central India and the rest of northwest India, an India Meteorological Department (IMD) update said on Monday.
This sets the stage for the revival of rain activity, with Kalpana-1 satellite pictures revealing the presence of convective(rain-bearing) clouds over east Uttar Pradesh, Bihar, Orissa, Andhra Pradesh, the North-Eastern States, Bay of Bengal, Andaman Sea and east-central and south-east Arabian Sea.
OFFSHORE TROUGH
A conventional offshore trough has fallen into place along the west coast from Maharashtra coast to Kerala coast.
This is just as well, since monsoon easterlies would need a system to interact with and bring needed rains into the region including West Rajasthan and north Gujarat where rains have been either deficient or scanty until now.
A short-term forecast by IMD valid until Thursday said that fairly widespread rain or thundershowers would occur over western Himalayan region, Uttar Pradesh, Chhattisgarh, Orissa, Lakshadweep, the Andaman and Nicobar Islands and along the west coast.
WEATHER WARNING
Scattered rain or thundershowers would occur over remaining parts of the country outside Rajasthan and Gujarat.
An extended forecast valid until Saturday spoke about the possibility of further increase in rainfall activity over central and northwest India.
But in a weather warning for the next two days, the IMD said that there are two remnant rain-driving circulations from the heavy session still hanging over the region over northwest Uttar Pradesh and Jharkhand and adjoining Bihar respectively.
SOUTHWEST COAST
Isolated heavy rainfall would also occur over coastal Karnataka, Kerala and the North-Eastern States during this period as the revival of monsoon reverberates along the southwest coast as also in the northeast.
Meanwhile during the day yesterday (Sunday), fairly widespread rainfall was reported from Jharkhand, West Bengal, Sikkim, north interior Karnataka and the Northeastern States
Monsoon :: At least 10 out of the 36 Met sub-divisions have had deficient to scanty rainfall ... http://bit.ly/lvrNvg
Morning, Heavy cloud activity can be seen over W.Bay due to the N-W Bay circulation along Orissa coast .. http://ping.fm/s2EAz
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.Soucre:Deccan Herald
