Tonga volcano: winter cold due to a huge outbreak in the stratosphere!
Tonga, Tonga - The outbreak of Hunga Tonga-Wilter Ha’apai Vulkan On January 15, 2022, one of the greatest geophysical events in modern history turned out to be one of the greatest geophysical events. According to Kleine Zeitung , this eruption was comparable to the devastating Krakatau-Eruption, which more than 36,000 human life cost. The volcano hurled about 150 megatons of water vapor into the upper atmosphere, which led to a global climate event.
The eruption not only produced a tsunami, but also a sound boom that circumnavigated the earth twice. Nasa’s Microwave Limb Sounder (MLS) detected that about 146 teragram of hydrogen steam came into the stratosphere, which corresponds to about 10 % of the existing water in this layer. This is almost four times as much as the amount that Mount Pinatubo was able to leave in 1991, as
Der Wasserdampf und das Schwefeldioxid, welches in die Stratosphäre gelangte, haben weitreichende Auswirkungen auf das globale Klimasystem. The chemical and physical changes were even measurable in Europe. The study by Aleš Kuchař from the Boku Institute for Meteorology and Climateology shows that the eruption resulted in a significant cooling of the stratosphere, which was up to four degrees Celsius in some places and lasted until mid -2023. This cooling was obviously in Europe, North America and parts of Asia during the winter of 2022/2023, which was characterized by exceptionally cold weather. The additional water vapor could also have influenced the ozone concentrations and temperatures over the tropics and make cold air more easily in southern regions. This contributes to research on the effects of volcanic eruptions on the climate, a topic that is becoming increasingly important through climate change, such as Euronews emphasized. The long-term consequences of the Tonga outbreak are still unclear because the eruption did not release large amounts of aerosols that could reflect sunlight. This fact could potentially lead to short -term warming of the earth's surface because water vapor stores heat. In addition, the water vapor could remain in the stratosphere for several years and thus further influence the chemical composition of the atmosphere. Vulcan eruptions have always been part of the climate system and can have significant effects, especially if they take place in tropical regions. As historically, severe outbursts have often changed the global climate temporarily. Investigation of these relationships remains a promising field for scientists, since the influence of volcanic activities on the climate is a complex matter that is not yet fully understood. influence on the climate
