To me winter is cold, ice, and snow, so for this gallery I use the meteorological winter definition, which encompasses the three coldest months of the year, running from December 1 to the end of February, rather than the more common astronomical winter definition, which is based on the position of the sun and runs from winter solstice to spring equinox. I also include any photos from late autumn that look like winter (i.e. contain ice or snow).
