Editing Belleville, Ontario (section)

===Climate===
Belleville's climate has four distinct seasons. The city's traditional [[humid continental climate]] ([[Köppen climate classification|Dfb]]) (hot summers, cold winters) is moderated by its location near Lake Ontario. The lake moderates temperature extremes, cooling hot summer days and warming cold days during the fall and winter.<ref>{{cite journal |last1=Berrang Ford |first1=Lena |title=Climate Change and Health in Canada |journal=McGill Journal of Medicine |date=January 2009 |volume=12 |issue=1 |pages=78–84 |pmid=19753294 |pmc=2687921 }}</ref> Because of this, winter snowfall is somewhat limited due to the increased frequency of precipitation falling as rain during the winter months. In the summer months, severe thunderstorm activity is usually limited because of the non-favourable lake breeze conditions. The city, being located on the north shore of Lake Ontario, is also in an unfavourable location for lake effect snow. One notable exception, however, was in December 2010 when 14&nbsp;cm of snow occurred in one day as a result of a snow band from Lake Ontario. The summer months do not typically experience exceedingly hot temperatures, however, humidity levels can make daytime highs uncomfortable. Summer rainfall is usually modest and delivered by passing thunderstorms or warm fronts. Remnants of tropical systems do pass through on occasion towards summer's end, resulting in one or two days of consistently wet weather. The winter season is highly variable, with the record setting winter of 2007–08 experiencing near 270&nbsp;cm of snow. Four years later, the winter of 2011–12 experienced only 60&nbsp;cm of snow. Winter temperatures are also highly variable, even in one season. Air masses change frequently, and while a few days may see above freezing temperatures at a time in January, the next week may bring cold and snowfall. Autumn is usually mild, with an increase in precipitation starting in late September as conditions for fall storms develop. The highest temperature ever recorded in Belleville was {{convert|104|F|1}} on 9 July 1936.<ref name="CCN" /> The coldest temperature ever recorded was {{convert|-39|F|1}} on 9 February 1934.<ref name="CCN" />
