Climatically | What is the relationship between the growing La Nina phenomenon and the recent worsening of global heat waves?

Arabia Weather - Meteorological specialists in the climate department at the Arab Regional Weather Center said that the world has recently witnessed, specifically with the second half of last May, a remarkable intensification in the intensity of heat waves, during which record numbers of temperatures were recorded at the global level. For example, the Indian capital, where... The historic temperature on Wednesday 5/29/2024 reached 52.9 degrees Celsius, and looking towards a longer horizon, the state of Texas recorded record temperatures that reached 51 degrees Celsius, exceeding the maximum temperature in Gulf capitals and cities in light of the presence of a new climate cycle that the world is witnessing, which is the state of La Nina. It is associated with heat waves.

Scientifically and climatically: The La Nina phenomenon is growing and announces the entry of a new climate cycle, and its effects are reflected in global temperatures.

The specialists at the Arabian Regional Weather Center said, after following up on the latest computer modeling outputs regarding the deviation of the temperature of water bodies from the averages, that the region located on the equator of the Pacific Ocean, specifically off the coast of Peru, has recently witnessed a clear cooling of the water surface temperature, as it has decreased from its averages by an amount ranging between One to two degrees, and this means that a new climate cycle has begun to appear in the waters of the Pacific Ocean, which is an increase in the climate phenomenon (La Nina), which will continue throughout the coming months, including the summer months of this year.

After conducting an extensive study, the specialists said that La Nina has a role in increasing the severity of heat waves in some regions around the world, and it is a natural climatic phenomenon characterized by the abnormal coldness of the waters of the tropical Pacific Ocean. Although the effects of La Nina are diverse and complex and vary according to the geographical region, they may lead to Increased severity of heat waves in some areas, for example:

• North America: La Nina can cause heat waves to become more severe in the southwestern regions of the United States.

• Australia: La Nina is associated with stronger heatwaves and more severe droughts in the eastern part of Australia.

Specialists pointed out that La Nina affects the pattern of air currents and global weather in multiple ways, which may lead to changes in temperature and precipitation in different regions of the world, but it cannot be certain that its effects will be inevitable in terms of its impact on the world’s climate, as all likely effects are the result of About statistical processing of the years in which this phenomenon occurred, with the need to emphasize that these climate cycles are only an integral part of giant patterns that drive global weather systems.

God knows.
