Another snowstorm hit Nova Scotia on Saturday. Winds reached over 100 km/h and thousands of people lost power in rural Nova Scotia as a sheet of ice blanketed the streets of Halifax.
The storm began in the early morning of January 29. Many businesses have closed preemptively in the city. Above, a girl crosses the street near the Osprey Roost butcher shop, one of the businesses closed by the storm.
The storm buried vehicles and froze streets, causing accessibility issues for many people across the city.
Some still braved the storm by car and on foot, but the town was pretty quiet until the storm subsided around 4 p.m. Then the excavations began.
On Sunday, the city woke up to a thick layer of ice all along the streets and sidewalks.
People dug up their vehicles and removed ice from their properties.
On Monday, the city was still trying to clear the icy streets and sidewalks.
It was the last gale of a wild winter month and the third weekend storm in four weeks. January was also marked by its strong temperature variations.
These temperature variations can be attributed to climate change, says a Dalhousie professor.
Phillip Bennett, professor of physics and atmospheric science, was answering questions about days like January 12, which saw a change of 21 degrees, from -20C at 8 a.m. that day, according to the weather trivia site www.weatherspark.com1 C at 11 p.m. that night and 2 C the next day.
He describes weather as “the process by which energy is transported”.
He said the temperatures we are experiencing are more extreme now because there is more energy transfer in the atmosphere.
Conditions on January 11 gave no warning of the drastic temperature difference that would occur the following day.
It was a cold day with a high of minus 11 and a low of minus 18. The forecast called for light snow and mist with mixed precipitation, but a mostly overcast day due to cloud cover.
During the first two weeks of January 2021, snowfall was recorded almost every day. This year, however, a mix of rain and snow was recorded on most days in the first two weeks of the year.
The greatest temperature fluctuation for the first two weeks of 2021 was recorded on January 11, with a maximum of 2°C and a minimum of -8°C, for a difference of 11 degrees.
Climate change has a direct effect on Earth’s weather and weather patterns, Bennett said.
He says these changes are not unusual, saying that “over time this kind of behavior is what you would expect.
“As you put more greenhouse gases into the atmosphere, you’re going to expect a stronger transfer of energy from the poles to the equator to the poles, and that will give you more of those abrupt weather events.”
Bennett thinks the weather will likely continue to be more extreme.
