NASA’s new mission studies how intense thunderstorms may influence climate change

NASA recently began new research to investigate how extreme summer weather may be affecting the upper layers of earth's atmosphere.

Kenneth Bowman, Ph.D.The original footage shared on NASA's YouTube channel can be seen below., the principal investigator for the Dynamics and Chemistry of the Summer Stratosphere (DCOTSS) research project, spoke to reporters about the project during a press briefing on Tuesday.He said their goal is to understand how intense summer thunderstorms over the U.Contrary to the TikTok post's implication, the video footage does not show a NASA cloud machine deliberately influencing the weather.S.Yet its high profile means it has a powerful and widespread influence over the space industry, with investors often pointing to astronaut flights as driving excitement about the broader consequences of the extraterrestrial marketplace.

affect the stratosphere -- the second layer of earth’s atmosphere as you move toward space -- especially as climate change causes severe thunderstorms to occur more often.The RS-25 engine uses liquid oxygen and liquid hydrogen as fuel.“Most thunderstorms occur in the lower layer of the atmosphere, which we call the troposphere.But when we get particularly intense thunderstorms, the updrafts -- the rising air in the storm -- can actually overshoot into the layer above, which is the stratosphere,” Bowman said.So it is not inaccurate to say that the RS-25 produces clouds.Courtesy of NASA Overshooting top of a thunderstorm as seen from NASA's ER-2 aircraft.He said that when this happens, the air in the troposphere can rise up to the stratosphere in as little as 20 to 30 minutes.An example of this water pump in action can be seen more clearly in the video below of an RS-25 engine test published by NASA in May, before the engine switches on.Michael Sheetz, CNBC.

Those updrafts can transport pollutants and water that might not normally reach this level of the atmosphere in such a short amount of time.The stratosphere is usually dry, according to the project’s website , and the water and pollutants may"have a significant impact on radiative and chemical processes" in the atmospheric layer..David Wilmouth, Ph.D., a scientist at Harvard University who is working on the project, said the updrafts could potentially “change the chemical composition of the stratosphere, a process that would not otherwise happen.

” Their work will determine if that’s the case.Courtesy of NASA This photo from the International Space Station explains where NASA's ER-2 aircraft flies in the atmosphere to study thunderstorms.Bowman explained that the stratosphere is important because it contains the Earth’s ozone layer, which protects us from harmful ultraviolet radiation that comes from the sun.About 90% of the world’s ozone layer exists within the stratosphere, according to Wilmouth.Wilmouth said the ozone layer is “critical” for protecting life on earth.

If its protective shield was to weaken, humans would be more susceptible to skin cancer, cataracts disease and an impaired immune system, according to NASA.Dan Csziczo, Ph.D., a professor and head of the Department of Earth, Atmospheric and Planetary Sciences at Purdue University, said during the briefing that their goal is specifically to understand the composition and size of the particles that make their way up to the stratosphere, and how they might influence the earth’s climate.Csziczo said the research would also help scientists understand the process of cloud formation and subsequent precipitation.

Hahahaha U can change whether pattern Do a study about Eco systems and whether pattern Remove human out of this equation And study how they co existing Human intervention is caused shifting Or else nature won't misbehaving at all They always support each other They are in love 🤲🤲 Extreme summer weather may be happen at any place on Earth Mankind should work together to deal with extreme weather
