June 2010: Drought in Sri Lanka is your fault; January 2011: Record rain in Sri Lanka is your fault - Tom Nelson

Droughts, floods, cold, heat and what have you, everything is climate change. Six months ago, Sri Lanka experienced a drought due to the El Niño effect and this month a flood due to the La Niña effect. "Sustainable or organic farming" had been given a big boost by humanitarian organizations after the Tsunami of 2004. 

And yet, the drought and floods within a space of six months have pushed Sri Lanka into a food crisis - the food shortage to be felt in the months ahead. All their "sustainable" experiments"washed away by these weather extremes.

When will NGOs get over their global warming obsession? They can  only start making an impact if they track ENSO (El Niño-Southern Oscillation)  a natural oceanic cycle, in their adaptation and mitigation programmes.

RT @emkay456: @weatherofindia so with withdrawal of NEM, r we set for WDs to start dipping down over Gujarat and Mah. .. EXACTLY !
El Niño and La Niña .. more on this ...
What helped bring rains in huge quantities over Rajasthan and Gujarat during the monsoon-2010 ??...
2010 was India's hottest year ...
Bijapur and Belgaum Airport recorded the lowest minimum temperature of 10 degree Celsius in the plains of S. India
16-Jan, mild showers over S. tamilnadu... Manimutharu and Papanasam (both Tirunelveli dt.) 1 CM
From 23-Jan a weak easterlies will start to fill over S-E Bay and will slowly move west.
3pm, Again entire S. Tamilnadu is covered with Medium high clouds...
An anti-cyclone will form over central India on 22-Jan and Entire Tamilnadu is goin to be WINDY from 21-Jan to 25-Jan..
3pm, Entire Kashmir, Himachal, Uttarakand, Punjab and Haryana is cloudy with rain and snow... Will last for next 24 hrs.

2010 was India's hottest year in recorded history

It now appears that the country may have endured the hottest year in 2010 in recorded history even as cold wave to severe cold wave conditions persist in north and north-west concurrently.
Mean annual temperature for the country as a whole during the last year was +0.93 deg Celsius above the 1961-1990 average.

It was slightly higher than that of the year 2009, making 2010 as the warmest year on record since 1901, an annual climate summary issued by India Meteorological Department (IMD) said on Friday.
Abnormally warm conditions (heat wave) prevailed over major parts of the country during March and April months claiming more than 300 lives.
The Pre-monsoon season was the warmest since 1901 with mean temperature being 1.8 deg Celsius above normal.
It is also found that the decade 2001-2010 has been the warmest decade with a temperature anomaly of 0.40 C.

The annual total rainfall for the country as a whole was normal during 2010 with actual rainfall of 121.5 cm against the long period average (LPA) of 119.7 cm.
Monsoon season contributes about 75 per cent of total annual rainfall for the country as a whole. Seasonal rainfall during 2010 was 102 per cent of its LPA.
Significantly, the IMD says that probabilities for La Nina conditions are 94 per cent or more through the January-February-March, 2011.
These conditions, which are considered monsoon-friendly, are forecast to not drop to below 50 per cent until the April-June season, the IMD outlook said.
Analysing the report, sources in the Ministry of Earth Sciences said the hot summer and the eventful wet to wetter season were not confined to India alone.

While parts of Europe experienced flooding conditions during the period under reference, Russia underwent the fiercest drought in living memory.
A warming anomaly materialised over India as a semi-permanent ridge (high-pressure system with dry, sinking air in contrast to low-pressure systems with moist, rising air) locked into position across the northwest border.
This had effect of shutting out the calming influence of western disturbances, allowing the hot climes to anchor themselves over the region.
Lesser movement of western disturbances, however, worked to the advantage of the country with the monsoon circulation spared of having to run into the opposing flows associated with western disturbances.
According to sources, this is what helped bring rains in huge quantities over Rajasthan and Gujarat during the monsoon.
Death toll due to heavy rains/floods during the monsoon was more than 500, mostly from northern and northwestern parts, the IMD report said.
A cloud burst in early hours of August 6 in Leh claimed more than 150 lives and more than 500 people are missing.
It is now a given that the atmosphere has warmed up to unprecedented levels, the sources explained. A warmed up atmosphere has the capacity to hold correspondingly larger amount of moisture.
Since the atmosphere cannot hold the moisture for too long, it cannot but precipitate. The air masses transport the moisture from areas of higher pressure to those of lower pressure.
Depending on locally evolving favourable conditions, clouds build up and the moisture gets precipitated.
The spatial distribution is not equal at any given point of time, with seasonal ‘hot spots' receiving the largest precipitation.
The monsoon region offers itself up as a ‘hot spot' and the weather gets amplified over disparate locations depending on extra moisture load in the air mass.
These phenomena are revealed in their gigantic size and scale in the deep ocean basins of the Pacific and the Atlantic where tropical storms and cyclones sustain themselves for up to a week.
Not to the same extent in the rather ‘closed basins' of the Arabian Sea or the Bay of Bengal where these systems can live up to three or four days at the most.
Chennai - after a 20 Deg Morning.. around 2pm felt bit Warm and stiff breeze now 4:22pm from East over Sea.
No dense fog would prevail over the country during next 3 days
Northwesterly/westerly winds are prevailing over plains of northwest India and adjoining central India
Cold/severe wave conditions are prevailing over Madhya Pradesh, Chhattisgarh ,Rajasthan,
U.P, Bihar, Jharkhand, Gujarat and interior Orissa
Finally, IMD :: Northeast monsoon rain has ceased today over Tamil Nadu, Kerala and adjoining parts of Karnataka & Andhra Pradesh
