00:00India has recorded the warmest October since 1901, and the winter that everyone has been

00:18waiting for hasn't arrived yet.

00:20Earlier, it was said that this year's winter will be harsh.

00:23India may experience extreme winter.

00:25This year, it will be Karachi's winter.

00:27Then why is it hot?

00:29Is it because of Diwali's firecrackers or climate change?

00:33Today, in Andekha Nazariya, we will understand the hidden reasons behind this.

00:37IMD's chief Mrityunjay Mohapatra says that the main reason for unusual warmth is Western

00:43disturbances and warm easterly winds due to active low-pressure systems in the Bay of

00:47Bengal.

00:49Now, what are these Western disturbances and low-pressure systems?

00:53Western disturbances are those weather systems that mostly form in the Mediterranean region

00:59and then move towards the east, towards India.

01:02As the name suggests, these disturbances come from the west and go towards the east.

01:07In these disturbances, the air pressure is less than normal, which pulls the air and

01:12clouds are formed, which change the weather.

01:15When WD comes, it brings warm and moist air first.

01:19And when it passes, it brings cold and dry air.

01:23It brings moisture from the Mediterranean and Atlantic Oceans, which brings winter rain

01:28in the plains and snows in the mountains of northern India.

01:31This rain and snow are Rabi crops, which are essential for wheat, which grow in winter.

01:36These disturbances work like natural coolers, which reduce the temperature during winter.

01:42This is why it is cold in India.

01:45When WD is less, natural cooling is also reduced, which makes winters warm.

01:51In recent years, WDs have weakened due to climate change.

01:55For example, in areas like Uttarakhand and Himachal Pradesh, there has been very little

02:00rain between October and December.

02:02And in Jammu and Kashmir, snowfall has also decreased.

02:05This decline in WDs is greatly affecting the growth of Rabi crops.

02:09When we do not get this moist air, the yield of crops and the availability of water in

02:14these areas are affected.

02:16This year, when WDs were mostly absent, natural cooling days were less in northern India,

02:21which made the temperature warmer than normal.

02:24Due to active low-pressure systems in the Bay of Bengal, the easterly winds are influxing,

02:29which are warm.

02:30These winds bring warm air towards India, which increases the temperatures.

02:35The late arrival of cold weather can mainly be due to neutral El Niño conditions,

02:40which is continuing in the equatorial Pacific Ocean.

02:43Now what is El Niño and its sister La Niña?

02:46El Niño and La Niña have changes in temperature near the equator of the Pacific Ocean,

02:51which affect the weather patterns of the world, including India.

02:55During El Niño, when the water in the Pacific is hot, it changes the flow of the air and

03:00shifts the usual weather patterns.

03:03Normally, hot air rises above the Pacific Ocean, which creates rain clouds,

03:08which travel towards India.

03:10But when the Pacific is hot, this process gets disturbed,

03:14which usually makes India's monsoon season weak and dry.

03:18This can cause droughts.

03:20During La Niña, when the water in the Pacific is cold,

03:23this makes the air and rain clouds more tendent towards India,

03:27which causes more rain and thunderstorms.

03:30If this extra rainfall is too much, it can also lead to flooding.

03:33In winter months, due to La Niña, a cold wave jet stream flows along Afghanistan,

03:37Iran and the Hindu Kush mountains.

03:40This cold and strong winds increase the cold in India.

03:44So basically, due to neutral El Niño conditions, India's weather is warmer.

03:48And when La Niña conditions develop, we can expect cold.

03:52All the countries of Asia, from Pakistan to Japan,

03:55are experiencing record-breaking high temperatures,

03:58which are mainly due to the warming of the oceans and climate change.

04:02The IMD has predicted a warm winter for November.

04:06But if La Niña settles, it can also be a wet month.

04:11Rising temperatures and climate shifts are impacting every aspect of India.

04:16For the past three years, severe heat waves have affected many parts of India,

04:20which is having a negative impact on health, water supply, agriculture, fire generation and the economy.

04:25Last year, floods troubled Himachal Pradesh and Uttarakhand.

04:30And in Sikkim, due to a glacial lake outburst flood, a hydroelectric dam collapsed,

04:36which killed more than 100 people and affected more than 88,000 people.

04:41The economic impact of climate change is also quite deep.

04:44India's economy depends on about one-third of nature.

04:48And if we don't do anything now,

04:50according to estimates, 15 million people can go back to poverty by the end of this century.

04:55So what can we do?

04:57We can use green energy sources,

05:00such as solar panels,

05:02means we can use public transport,

05:04we can turn off the lights when they are not needed,

05:07and we can design houses that are well ventilated,

05:11so that the use of AC is less.

05:13But if we want a more impactful work,

05:16then we should make politicians accountable for their promises to reduce industrial pollution,

05:21and we should pressurize them to take action.
