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.

Snowpack is an accumulation of snow that compresses with time and melts seasonally, often at high elevation or high latitude. [1] [2] Snowpacks are an important water resource that feed streams and rivers as they melt, sometimes leading to flooding.

There are two types of polar climate: ET, or tundra climate; and EF, or ice cap climate.A tundra climate is characterized by having at least one month whose average temperature is above 0 °C (32 °F), while an ice cap climate has no months averaging above 0 °C (32 °F). [2]
An impact winter is a hypothesized period of prolonged cold weather due to the impact of a large asteroid or comet on the Earth's surface. If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere , blocking the radiation from the Sun .
