The seven-phase Lok Sabha polls season will witness an unprecedented rise in the heatwave in most parts of the country, the India Meteorological Department warned here on Monday. While above-normal temperatures are likely almost all over the country, 10-20 days of heatwave is expected between April and June in different parts against normal of 4-8 days. The most heatwave prone areas are Gujarat, central Maharashtra and north Chhattisgarh, Odisha and Andhra Pradesh. “More heatwave days are expected in an El Nino year. The El Nino (an unusual rise of temperature in the Pacific Ocean with impacts all over the world) is still there in April-May even though it is receding and may become neutral by June,” Mrutyunjay Mohapatra, director general of meteorology at the IMD said.

00:00 Who doesn't love to chill in the rain and get rid of the hot summer?
00:11 With the early advent of summer-like season this year, people already are eagerly waiting
00:16 for the monsoon.
00:17 But, do you know that the monsoon, which brings rain on the Indian subcontinent, is affected
00:23 by a number of natural phenomenon?
00:25 Two of the most important of these are El Niño and La Niña.
00:30 These two weather phenomena doesn't affect only the Indian subcontinent but the whole
00:34 world.
00:35 So, what exactly are these phenomena and how do they affect climate?
00:39 Let's understand in this video.
00:42 El Niño and La Niña are two weather phenomena that occur in the Pacific Ocean and can have
00:48 a significant impact on global weather patterns.
00:51 These events are part of a larger climate pattern known as the El Niño-Southern Oscillation
00:57 or the ENSO, which is a natural cycle that occurs every 2 to 7 years.
01:02 The term El Niño means "the boy child" or "the Christ child" in Spanish as it affects
01:08 the oceanic currents during Christmas.
01:11 El Niño occurs when warm ocean water in the central and eastern Pacific moves eastward
01:16 towards South America.
01:18 This warm water causes changes in atmospheric circulation, leading to changes in weather
01:23 patterns around the entire world.
01:25 During an El Niño event, parts of South America experience very heavy rainfall, while parts
01:31 of Asia and Australia may experience drought conditions.
01:34 So, whenever Indian subcontinent receives less rainfall, it is usually because of El
01:40 Niño.
01:41 On the other hand, La Niña occurs when the ocean water in the central and eastern Pacific
01:46 is colder than average.
01:48 This leads to changes in atmospheric circulation that can cause opposite effects to El Niño.
01:53 During a La Niña event, parts of South America may experience drought conditions, while India,
01:59 other parts of Asia and Australia may experience very heavy rainfall.
02:04 In North America, La Niña can cause colder and drier conditions in the southern part
02:08 of the continent, while the northern part may experience warmer and wetter conditions.
02:13 While El Niño and La Niña events are natural phenomena, they can have significant impacts
02:18 on human societies, especially those that rely on agriculture, fishing, and other weather-dependent
02:24 industries.
02:25 In some cases, these events can lead to severe weather events such as floods, droughts, and
02:31 hurricanes which can have devastating effects on communities.
02:35 In recent years, there has been growing concern about the potential impact of climate change
02:39 on El Niño and La Niña events.
02:41 Some scientists have suggested that global warming may lead to more frequent and intense
02:46 El Niño events, while others believe that La Niña events may become more common.
02:52 This could have significant implications for global weather patterns and could exacerbate
02:56 the impacts of climate change on vulnerable communities.
02:59 Despite the potential risks associated with El Niño and La Niña, these events also provide
03:04 an opportunity for scientists and policy makers to better understand the complex interactions
03:09 between the ocean and atmosphere.
03:12 By studying these events, we can develop better predictive models and early warning systems,
03:17 which can help us prepare for severe weather events, thereby preventing loss of lives of
03:22 hundreds of thousands of people every year.
