Researchers recently have found a surprising and 1 (benefit) impact of lightning with the result of a study 2 (publish) in Science. The study found that lightning may play a bigger role in global climate change 3 was previously known by the scientific community. “Lightning increases the atmosphere’s ability to clean itself, the researchers wrote in the study.
The Earth 4 (strike) by lightning nearly 20 million times each year, which travels as much as 10 to 12 miles from a thunderstorm, thus instantly 5 (heat) the air to 50,000 degrees Fahrenheit (华氏温度) according to the National Weather Service.
Researchers realized that the increase in hydroxyl radicals (羟基自由基) in the atmosphere 6 they observed was connected to the lightning 7 (flash). Hydroxyl radicals, also described as a “chemical cleaner”, were important chemical compounds (混合物) found in the atmosphere. As 8 result, the study predicted that between 2% and 16% of the oxidizing (氧化) or cleaning is done by lightning. The oxidizing or cleaning happens 9 (natural) in the Earth atmosphere.
