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.
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]

The climate of western Europe is strongly conditioned by the Gulf Stream, which keeps mild air (for the latitude) over Northwestern Europe in the winter months, especially in Ireland, the United Kingdom and coastal Norway.
Westerly winds bring the warm air currents into the Baltic areas and to the country's shores, moderating winter temperatures, especially in the south and southwest in cities like Helsinki and Turku where winter highs tend to be between 0 and 5 °C (32 and 41 °F) but a cold snap like the one that occurred in mid-January 2016 can cause ...
Even though the "meteorological winter" in the Northern Hemisphere runs from the first of December until the last day of February, the actual moment of the winter solstice this year will be at 10: ...

On average, most of Sweden receives between 500 and 800 mm (20 and 31 in) of precipitation each year, making it considerably drier than the global average.The south-western part of the country receives more precipitation, between 1,000 and 1,200 mm (39 and 47 in), and some mountain areas in the north are estimated to receive up to 2,000 mm (79 in).
At least three times as much precipitation in the wettest month of winter as in the driest month of summer, and the driest month of summer receives less than 30 mm (1.2 in). Dsc = Mediterranean-influenced subarctic climate; coldest month averaging below 0 °C (32 °F) (or −3 °C (27 °F)) and one–three months averaging above 10 °C (50 °F).
