Making noise

2 big noise events have taken up residence in my brain lately.

The first is about the noise that accompanied Canada’s derecho. The information below are excerpts from the CBC report.

What’s a derecho and why is it so destructive? The science behind this powerful storm

Canada’s last derecho was in 1999, but climate change is shifting conditions

An ominous wall of wind and rain

A derecho, pronounced deh-RAY-cho, is a long-lived, fast-moving thunderstorm that causes widespread wind damage. This particular storm system was fed by a heat dome over the eastern United States. 

According to Sills, the system formed south of Chicago on Saturday morning, then crossed the border into the Windsor area, where it started to cause damage. 

By the time it arrived in Kitchener, Sills said the thunderstorm was producing gusts of up to 132 km/h. 

Unlike the rotating winds in a hurricane or a tornado, a derecho’s winds are straight. That doesn’t mean it’s any less damaging; its winds can topple trees and lift up roofs. Another feature of a derecho is that unlike the slow building of a supercell thunderstorm, the business end of a derecho is at the front. 

That’s why when you witness a derecho, Stills said, it often looks like an ominous wall of wind and rain. 

“When it hits, usually the worst of it is within a couple minutes of it hitting,” he said. 

Making that destructive wall of wind even worse, is that it can sometimes produce tornadoes as well.

“Really, it’s just a spectrum of wind that affects a long area,” Sills said. 

So far, field crews with the Northern Tornadoes Project have identified at least one EF2 tornado, which hit Uxbridge, Ont., with wind speeds of up to 195 km/h.

The last string of derechos that hit Canada were in the 1990s, including one in 1999. According to the U.S. National Oceanic and Atmospheric Administration, that storm cut a path through Thunder Bay and sparsely populated areas of northern Ontario before crossing into Quebec, where it killed one person, toppled trees, damaged buildings and overturned boats in the Montreal area.

“It is the widespread nature of a derecho that can really cause havoc in a city,” Sills said. 

What made Saturday’s storm especially unlucky was that several urban centres were directly in its path.

“This was an unusual event because it affected the most populated part of Canada,” Kimbell said.

Still, the storm left a path of destruction in its wake, killing 10 people and leaving roughly 900,000 homes and businesses without power in Ontario and Quebec at its peak. It continued all the way to Maine, where there were also reports of damages.

Climate change could bring more derechos

Pinning down whether or not the rare event could be linked to climate change is difficult. Because derechos are so infrequent in Canada, Sills said it’s impossible to say whether they’re increasing or not. 

But, he said, the ingredients necessary to form a derecho “may come together more often” as a result of the effects of climate change.

A derecho happens when there’s a lot of heat and moisture available and they are often tied to heat domes. Sills said climate projections point to a warmer atmosphere that will creep northward, which means this is the kind of storm Canadians can expect to see more of in the future. 

There is always something to learn from extreme weather events, Sills said, and a key takeaway for him after this storm is that computer modelling needs to catch up.

“There wasn’t much in the way of any indication in the models of this big derecho coming through,” he said.

“The computer models we rely on to give us a heads up for these types of events, they’ve got a long way to go.”

THEN THERE IS THE NEXT BIG NOISE

A horrendous massacre in Uvalde Texas, a small town this Canadian lived in twenty-seven years ago for a bit. Tragedy, blood, shame.

And what is the big noise of this? All the bleeping indignation from everyone from the President on down.

THINGS MUST CHANGE they all cry. My response? STOP THE BLEEPING INDIGNATION and talking about what should be done.

JUST DO IT. DO IT. STOP THE TALK. TALK IS CHEAP. STOP THE INDIGNATION. JUST STOP WITH THE WORDS. TAKE ACTION. NOW.

That cry – that plea applies to more than the USA. It applies to my country whose sad response to everything has become ’WE WILL CONSIDER,…WE MIGHT,…disgusting way for leaders anywhere to behave.

So sadly that is about all I have to say from North of 43 tonight. Tomorrow will be a brighter day here, but sadly nothing will be done about ALL THE NOISE

One is about 43 degrees latitude N. and longitude 80 W, The other almost equidistant south latitude and longitude 174 E. Two women, two minds, different personalities and experiences, choosing a life of meaning, continual growth and learning, at the same time negating ageist opinions of exactly what ‘an old lady’ should be.

  1. Your storm/derecho is acary. Here in Windy Wellington we have high-speed winds but not the destruction that you comment on. And the shooting? When will the words stop and action start. I noticed a comment from that film star Matthew McConachie who used to live in Uvalda.. But more angry words! Time NOW for action.

  2. We can’t do anything to prevent so-called “acts of God” – like derechos and tornados – but we can be prepared to meet them (don’t ask me how, not my area of expertise!). But mass shootings are something that could so easily be prevented by proper legislation and enforcement of that legislation. Why isn’t that happening in the USA? But calling for a “strong man” isn’t the answer – Russia has one of those, and look at the havoc he is wreaking right now.
