Meanwhile in B.C.
Her comments come as British Columbia’s coast braces for intense winds brought by a bomb cyclone, a non-tropical storm system caused by a rapid drop in atmospheric pressure at its centre.
Environment Canada warns it could bring gusts of 120 km/h to the central and north coasts, with winds of 100 km/h or more elsewhere on the coast and Vancouver Island.
Day says the term “bomb cyclone” has been used by scientists for decades and describes “a low-pressure system that is undergoing explosive cyclogenesis,” or the creation of cyclonic air circulation.
She says terms like “bomb cyclone” and “atmospheric river” can often help paint a picture that allows people to better understand and prepare for various weather systems.
In British Columbia, an atmospheric river originating near Hawaii has long been known as a “pineapple express.”
“So, an atmospheric river — right away, people start to think, ’OK, it’s a narrow band of moving water,”’ Day said.
“It does give you the sense that this is going to be a steady event and that there’s not going to be time for the ground to absorb the rain. It’ll continue to rain and eventually cause flooding because of that concentrated rainfall.”
Day noted that she had received “a lot of grief” for using the term “bomb” in relation to meteorological phenomena, with some accusing her of trying to sensationalize weather events.
“I really believe that if they’re used in the proper context, that they’re not alarmist,” she said.
“As long as the people know that they’re getting their information from a qualified source, and that source (or) that person is using the terms correctly and not shouting out ’bomb’ every time there’s an area of rain coming in, I think it’s really important to understand those words and to take them seriously and to know that they’re based in meteorological fact, in science.”
