Manali today had snowfall.

Image of prediction at Manali for snowfall:


A Bcmtian reported:
Snowfall happened yesterday night also around 10.30 pm.

woke up to a white morning...
but it has been raining so all that white will go away shortly.
Snowfall started again.
It is switching between rain and snow..
so enjoy it while it lasts.


Reason ?
That is cause lot of moisture coming up into that valley, and the wind has to climb up the valley to cross Rohtang, So you will have these intermittent spells.
Have fun.

Stalagmite Holds Key To Predicting Droughts, Floods In India: Study

By studying the last 50 years of growth of a stalagmite from Mawmluh Cave in the northeastern Indian state of Meghalaya, they found an unexpected connection between winter (dry season) rainfall amounts in northeast India and climatic conditions in the Pacific Ocean.

Stalagmite Holds Key To Predicting Droughts, Floods In India: Study


Stalagmites indicate recurrence of intense, multiyear droughts in India over the last thousands of years.


NEW DELHI:
Stalagmites can help scientists predict droughts and floods in India, a recent study suggests. To unlock some secrets about climate change, a team of researchers went to an unusual cave in India.
By studying the last 50 years of growth of a stalagmite from Mawmluh Cave in the northeastern Indian state of Meghalaya, an area that experiences so much summer monsoon rainfall that it is called the rainiest place on Earth, they found an unexpected connection between winter (dry season) rainfall amounts in northeast India and climatic conditions in the Pacific Ocean.
Winter rainfall following weak monsoon years in India can alleviate water stress for farmers. This distant link between land and ocean records could aid in predicting dry season rainfall amounts in northeast India.
Each year, monsoon rains between June and September provide water for roughly 1.5 billion people in India. Changes in monsoon strength and the timing of its onset or withdrawal can trigger either drought or flooding, with devastating consequences, highlighting the need for effective ways to predict and prepare for rainfall variations.
Stalagmites from Mawmluh Cave and the surrounding region indicate the recurrence of intense, multiyear droughts in India over the last several thousand years. In fact, stalagmite records from monsoon regions, including India, are vital to understanding past variability in the global climate system and the underlying reasons for this variability. Scientists typically look to those records to reflect changes in the amount of monsoon rainfall and changes in monsoonal circulation in the atmosphere. The potential influence of rainfall during winter is often overlooked.

"Counterintuitively, air and water circulation in caves can cause, and even favor, stalagmite growth in the dry season, leading to unexpected effects in paleoclimate records," said Elli Ronay, one of the lead researchers.
In a recent paper published in the journal Scientific Reports, Ronay, Jessica Oster, lead author of the study, detail their sub-seasonally resolved reconstruction of trace element compositions from the Mawmluh Cave stalagmite, providing information about local changes in hydrology. Comparisons of cave records and nearby rainfall data show that variations in dry season rainfall rather than the monsoon rains govern variations in trace element concentrations in the stalagmite and how the amount of variation changes from year to year.



COMMENT
These new results advocate for caution when interpreting stalagmite records from regions characterized by strong seasonality like the monsoon. They also suggest that potentially powerful information about annual rainfall variability in northeast India has gone unnoticed in stalagmite records thus far.

Beginning with North, no significant weather system is seen over the regions. With this, northerly winds are likely to prevail over the hills and adjoining northwest plains. The windspeed over northwest plains is expected to reduce. Sky would be clear with comfortable weather conditions over the hills. Morning to remain cool over the region. While, day and night temperatures would rise over Punjab, Haryana, Rajasthan, Delhi and Uttar Pradesh. Also, heatwave conditions might develop over Barmer, Jaisalmer and Jalore.
Similar heatwave conditions would extend till Central India in some parts of Gujarat, Madhya Maharashtra, Marathwada, Madhya Pradesh and Vidarbha. While isolated pockets of severe heatwave conditions might be a sight in parts of West Madhya Pradesh.


In East, a Cyclonic Circulation is over North Bengal and adjoining Bihar. Another Cyclonic Circulation is over East Assam. The east west trough is connecting both these circulations. Simultaneously, a trough from North Bengal to North Bay of Bengal can be seen. In the presence of these weather systems, moderate rain and thundershower activities are likely at many places of northeastern states with heavy over Tripura, Meghalaya, Manipur, Mizoram and South Assam. Isolated pre-Monsoon rains and lightning strikes might be a sight over northeast Bihar, North West Bengal and adjoining Jharkhand. Thunderclouds might also develop in parts of coastal Odisha.

Down South, a Cyclonic Circulation lies over Karnataka and adjoining Telangana. A trough is extending from this system up to extreme South Tamil Nadu across Kerala. Rain and thundershower activities would be seen at isolated places of Telangana. Karnataka, extreme parts of South Tamil Nadu and Kerala might witness scattered rains.
Heatwave can further tighten its grip over Telangana. Temperatures to remain above normal for most of the places in South Peninsula with humid conditions to persist. Bengaluru and Chennai would be warm and humid. While, Hyderabad will experience hot and humid weather with chances of thundercloud development.

Heat wave conditions experienced in Delhi

PTI | Updated: Apr 5, 2019, 22:16 IST



Children cool themselves to beat the heat near India Gate as temperature soars in Delhi on Friday.

Heat wave conditions experienced in Delhi

NEW DELHI: Heat waveconditions were experienced in several parts of the national capital on Friday, with the maximum temperature settling at 39.3 degrees Celsius.

The Safdarjung observatory, the recording of which is considered the official figure for the city, registered a maximum temperature of 39.3 degrees Celsius, five notches above the season's average while the minimum temperature was 20 degrees Celsius, a notch above the normal, said an IMD official.


The Palam observatory recorded a maximum temperature of 40.8 degrees Celsius, while areas under Lodhi Road, Ridge and Ayanagar recorded a high of 39.6, 38.3 and 39.7 degrees Celsius, respectively.

The humidity oscillated between 87 and 32 per cent.

The weather office has forecast partly cloudy skies along with the possibility of thunderstorm and dust storm accompanied by moderate squall for Saturday.


The thunderstorm and the dust storm are expected because of a feeble western disturbance currently lying over east Afghanistan and adjoining Pakistan and a cyclonic circulation over Rajasthan, said B P Yadav, head of the India Meteorological Department's (IMD) Regional Meteorological Centre.


"Already thunderstorm and dust storm activity is being reported in Rajashan and south east Haryana during the evening hours and clouds are approaching the national capital. There is a possibility of a moderate thunderstorm and dust storm towards night or tomorrow (Saturday)," Yadav said.


"The maximum and minimum temperatures are likely to hover at 38 and 20 degrees Celsius, respectively on Saturday," the weatherman said.


On Thursday, the maximum and minimum temperatures settled at 38.2 and 18.7 degrees, respectively.

NEW DELHI: The ministry of environment, forests and climate change (MoEFCC) has submitted an affidavit to the National Green Tribunal (NGT), advising the Delhi government to incorporate a heatwaveaction plan for the capital as part of the Delhi state action plan on climate change.


The national steering committee on climate change at MoEFCC stressed on the need to look at a comprehensive action plan for long-term measures, which need to include preparations for an intense heatwave in the region. At present, Delhi is witnessing heatwave conditions in certain parts with a maximum temperature of 39.3 degrees Celsius recorded on Friday, five notches above normal for this season.


Heatwave conditions occur when the maximum temperature is at least four degrees above normal and even higher. Delhi government had submitted its state action plan in January. However, all long-term plans are passed through the MoEFCC. Officials said the changes were suggested in a recent meeting on the action plan. “The representatives of the Delhi government made a presentation on the state action plan on climate change. In the meeting, the importance of e-mobility and heatwave was highlighted by the members,” said an official, adding that specific directions on how to deal with sudden spikes in temperature would be given.


Earlier, Gaurav Bansal, the counsel appearing for the petitioner, had informed NGT that due to climate change, the capital was already facing problems like high temperature and instances of heatwave were increasing.
