Natural climatic variability, especially the child, may have influenced severe heat waves that hit India and Pakistan in mid -April, according to Climameter, a rapid experimental framework to put the climatic extremes in a climatic perspective.
The consequences extended beyond human health that impact essential services, education and food production, with experts warning about the growing vulnerability of both countries to such climatic extremes in the future, said Climameter’s analysis.
El Niño passive paper
He added a warning that, given that the current phase in the Equatorial Pacific is ‘neutral’ (Neinder the boy or the girl), the changes observed in the heat wave are probably due to the climate change driven by humans, with only one minor contribution.
Climameter evolved in Laboratoire des Sciences du Climat et de l’Endironment (Institut Pierre Simon Laplace in Paris-Saclay. He said that the weather conditions similar to the April event had risen to 4 ° C by this year. Eay.
Heat wave in mid -April
Duration from April 14 to 15, parts of Pakistan, particularly Baluchistan, saw temperatures fired up to 49ºC. In India, New Delhi reported temperatures of 40 ° C fixing size on multiple occasions, up to 5 ° C above the seasonal average. The heat wave was extended by neighboring states such as Rajasthan, where workers and farmers fought to work in abrasing conditions.
Meteorological patterns
The early shortage of heat and water assured that the agricultural sector was hard. Extreme temperatures also led to a greater demand for electricity, which worsens the shortage of energy. The dependence of the dependence on groundwater is negatively affecting the aquifers of the region. Adjusted events suggest that the meteorological patterns associated with the heat wave occur with the same frequency as in the past. Changes in urban areas reveal that New Delhi, Jaipur and Islamabad are experiencing warmer conditions, and Islamabad is more affected.
Pressure anomalies
Meteorological conditions were characterized by an unusual pattern of surface pressure anomalies, with negative (lower) pressure abnormalities dispersed on Pakistan and positive pressure abnormalities (higher) over the Himalayas. The lowest pressure meant increasing air, humidity, clouds and rain, while the greatest pressure brought descending air and dryness that did not allow clouds to be formed.
Temperature anomaliesReached up to +12 ° C Afghanistan, Pakistan and India. The precipitation data indicates dry conditions in the area affected by heat under quiet conditions (without wind), which simply exacerbated heating and discomfort.
Become common
The occurrence of large positive temperature anomalies and extremely dry conditions in the season before the Monzón (March to May) is becoming common in southern Asia, as evidenced by persistent events and extended spatially in 2015, 2019, 2022 and 2024, and temperature records are broken every few years, the weather analysis showed.
The IPCC AR6 report provides a clear relationship between thermal waves and climate change in southern Asia. Climate change contributes significantly to the increase in thermal waves in India through various mechanisms: heating has led to greater frequency, intensity and duration of heat -related events, including thermal waves in most 27).
Temperature peaks
Global warming and urbanization can improve heating in cities and their surroundings, especially duration thermal waves, with a greater impact on night temperatures than the temperatures of the day (IPCC AR6 WGII FR – Page 1058). The air temperature of the observed surface has increased since the twentieth century in Asia, an intense threat of heat waves throughout the region.
In southern Asia, specifically, the frequency and duration of heat waves have increased, associated with the heating of the Indian Ocean basin and the frequent children. The combination of global warming and population growth in cities already warm India is an important driver for exposure to incessant heat, with urban heat islands that raise temperatures in cities in relation to its surroundings.
