18 16 is called a year without summer, with snow in June and frost in July. What happened?
In fact, the so-called frost in June and July in In the snow actually happened not only in China, but also in the United States. 18 16, this phenomenon occurred in the United States and Canada. It is reported that in May 18 16, frost appeared in the northeastern United States, and most crops were frozen to death. In June, there were two snowstorms in the United States and Canada, and some people even froze to death. In July, rivers in Pennsylvania froze. What is even more frightening is that the temperature in some places is sometimes higher than 35 degrees Celsius, and suddenly drops to 0 degrees Celsius after a few hours, and crops freeze to death. However, not only the United States, Europe and even China have experienced extremely rare climate change. According to historical records, in the summer of 18 16 (twenty-first year of Jiaqing), the weather suddenly became as cold as winter, with severe frost in Heilongjiang in the northeast and snow in Anhui and Jiangxi in June and July. Then why on earth is there such a phenomenon of great climate change?
This is because 18 15 had a volcanic eruption. It was at 18 15 that the Tambora volcano on Sombawa Island in Indonesia began to rumble, and soon after, the volcano officially erupted. This volcanic eruption sprayed as much as 65,438+050 cubic kilometers of dust and rocks into the air. Volcanic ash and slag directly covered the Fiona Fang 100 mile area of Bawa Island, and the thickness even reached 3.7 meters. Moreover, the consequences of this volcanic eruption are far more than that. It also triggered a tsunami that killed more than 654.38 million people. Volcanic ash even rushed into the stratosphere, forming a huge gas of about 400 million tons, wrapping the earth layer by layer. This huge gas layer reacts in the atmosphere to form sol, which blocks and reflects sunlight, so that the heat of the sun can't reach the ground, so the ground climate changes dramatically and the temperature drops suddenly, resulting in the phenomenon of snow falling in June and frost in July, forming a year without summer.
