It was the year of too much 鈥� too wet, too dry, too hot, too cool.

鈥淚t wasn鈥檛 a typical Canadian kind of year, where if you don鈥檛 like the weather out your front door, look out your back door,鈥� says David Phillips, Environment Canada鈥檚 chief climatologist.

Phillips has just released his list of Canada鈥檚 Top 10 weather stories of 2017. If there is a common theme, it鈥檚 one of normal weather becoming abnormal simply by not changing.

For example, last spring the rain in British Columbia just wouldn鈥檛 stop. That was immediately followed by the province鈥檚 driest summer ever.

The result was the most disastrous fire season in B.C.鈥檚 history. Those fires, which forced 50,000 people from their homes, are Phillips鈥檚 nod for top weather story of the year.

All across the country, weather patterns that would normally move on after a few days lasted and lasted.

A huge dome of hot temperatures sat over the Prairies for most of the summer. Calgary had its hottest May through August since 1881.

The central Canadian spring began with floods in Quebec and eastern Ontario after persistent rains saturated a snowpack only half melted. The Windsor area recorded two storms of the century in less than a year.

Ontarians are calling 2017 The Summer That Wasn鈥檛 鈥� a cool, damp season of unrelenting disappointment. The province had more warm days after the official start of autumn than before.

Newfoundland was hit by a slow-moving blizzard that ravaged the island with winds of 190 kilometres an hour. It yanked trees from the ground, toppled traffic lights and blew off roofs as if they were dust specks.

Every part of the country, in every season, saw weather patterns that just wouldn鈥檛 quit, for good or ill. For an explanation, Phillips looks to the jet stream, a high-altitude, high-speed current of air that helps produce what we鈥檝e come to call normal.

It usually flows west to east in a more or less straight line from Victoria to St. John鈥檚, Nfld., cold air to the north and warm to the south. Last summer, it looped north of Tuktoyaktuk, N.W.T., then south of the Great Lakes, before heading back up to the Maritimes.

The so-called 鈥渓oopy鈥� jet stream tends to produce weather patterns that get stuck.

Emerging science suggests the unstable jet stream also may be linked to shrinking Arctic sea ice, says Phillips.

鈥淚 think it was a factor.鈥�

Phillips, like most scientists, stops short of blaming 2017 on climate change. But if it were climate change, 2017 is what it would be like.

鈥淧eople think with climate change, it鈥檚 all about warm, warm warm. But what you get is a shift in weather patterns, where you can actually end up with opposite of what you might think.鈥�

After a 22-year career in weather, Phillips says things have truly changed.

鈥淚 remember when I started my career, you鈥檇 get one season that was interesting. Now, every one has something to write about.

鈥淭he weather is changed. It has a different character, a different personality to it in its duration and intensity.鈥�
