The lingering effect of the volcanic winter of 536 was augmented in 539–540, when another volcanic eruption caused summer temperatures to decline as much as 2.7 °C (4.9 °F) below normal in Europe. [2] There is evidence of still another volcanic eruption in 547 which would have extended the cool period.
The conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption.
The eruption’s potential impacts to weather and climate are starting to come into focus, even as the danger posed by the volcano persists and evacuations continue.
The climate surrounding the volcano constrains the impact of the eruption. Models of eruptions that treat climatic variables as controls and hold eruption intensity constant predict particulate emissions, such as volcanic ash and other pyroclastic debris ejected into the atmosphere, in the tropics to reach higher altitudes than eruptions in ...
Volcanic eruptions in 19th century Japan were well-documented, and there were no records of a large eruption in 1831. ... “It seems plausible that volcanic climate cooling led to crop failure ...

Three large cooling periods caused by volcanic eruptions in 1641–1642, 1667–1694 and 1809–1831 respectively. [2] Also, some major volcanic eruptions caused the fall of the temperature. During the Little Ice Age, all major volcanic eruptions were stratovolcano, also known as composite volcanos. They were built by the escape of magma ...
The impact of the volcanic eruptions was the phenomenon known as volcanic winter. In the volcanic winter of 536, summer temperatures fell by as much as 2.5 degrees Celsius (4.5 degrees Fahrenheit) below normal in Europe. ("Normal" is considered by scientists to be the average temperatures of the 1961–1990 period.)
