After a volcanic eruption, evaporation over ocean will lower, because it is largely determined by the ocean surface temperature change. The quick response of evaporation to the surface cooling and the delayed response of river runoff to the associated lower precipitation lead to an increased sea level.
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 ...
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.
By providing a long-missing piece of information about the 19th century volcanoes that cooled Earth’s climate, “the study perhaps strengthens our confidence on the role of volcanic eruptions ...
Known as a super eruption for its magnitude, the event emptied out enough volcanic material to produce the 30-by-40-mile-wide caldera. The National Park Service said the eruption covered an area ...
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.
Since the initial eruption, the volcano has been releasing sulfur dioxide and nitrogen oxide — two gases that create acid rain when they interact with water and oxygen in the atmosphere. With ...
