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.
