Ukrainian President Volodymyr Zelenskyy will address the Canadian Parliament on Friday as he continues his efforts to shore up support from Western allies for Ukraine’s war against the Russian invasion.
Zelenskyy arrived at Ottawa’s airport late Thursday after meeting with US President Joe Biden and lawmakers in Washington, Prime Minister Justin Trudeau’s office said.
Trudeau greeted Zelenskyy and will also speak in Parliament in Ottawa on Friday, The Associated Press said.
It is Zelenskyy’s first visit to Canada since Russia invaded Ukraine in February 2022. He previously addressed the Canadian Parliament virtually after the war started.
Zelenskyy and Trudeau are scheduled to go from Ottawa to Toronto to meet with the local Ukrainian community. Canada is home to about 1.4 million people of Ukrainian descent, close to 4% of the population.
The Ukrainian president is making the trip after stops at the United Nations and the White House.
Canada's UN ambassador, Bob Rae, said it is important for Zelenskyy to see the extent to which Canada supports Ukraine in the war.
“We have done a lot to help him and we need to do more,” Rae said. “We’re going to continue to do everything we can to support the Ukrainian people."
Canada has provided more than $8.9 billion Canadian (US$6.6 billion) in support to Ukraine in what Trudeau's government calls the highest per-capita direct financial support to Ukraine in the Group of 7 industrial nations.
More than 175,000 Ukrainians have come to Canada since the war started and an additional 700,000 have received approval to come as part of an initiative that supports temporary relocation of those fleeing the war. The initiative allows for an open work permit for three years with pathways to permanent residency and citizenship.
Zelenskyy is facing questions in Washington about the flow of American dollars that for 19 months has helped keep his troops in the fight against Russian forces.
Ukrainian troops are struggling to take back territory that Russia gained over the past year. Their progress in the next month or so before the rains come and the ground turns to mud could be critical in rousing additional global support over the winter.
Zelenskyy made his first official visit to Canada in 2019.

As if they aren’t already facing enough, firefighters in California also could encounter fire tornadoes — a rare but dangerous phenomenon in which wildfires create their own weather.

The National Weather Service warned Tuesday that the combination of high winds and severely dry conditions have created a “particularly dangerous situation” in which any new fire could explode in size. The advisory, which runs into Wednesday, didn’t mention tornadoes, but meteorologist Todd Hall said they're possible given the extreme conditions.

 

A look at fire tornadoes according to The AP.

What is a fire tornado? Fire whirl, fire devil, fire tornado or even firenado — scientists, firefighters and regular folks use multiple terms to describe similar phenomena, and they don’t always agree on what’s what. Some say fire whirls are formed only by heat, while fire tornadoes involve clouds generated by the fire itself.

The National Wildfire Coordinating Group’s glossary of wildland fire terms doesn’t include an entry for fire tornado, but it defines a fire whirl as a “spinning vortex column of ascending hot air and gases rising from a fire and carrying aloft smoke, debris and flame,” and says large whirls “have the intensity of a small tornado.”

Wildfires with turbulent plumes can produce clouds that in turn can produce lightning or a vortex of ash, smoke and flames, said Leila Carvalho, professor of meteorology and climatology at the University of California, Santa Barbara.

“There is a rotation caused by very strong wind shear and a very hot, localized low-pressure system,” she said.

What is a fire tornado capable of? Fire tornadoes can make fires stronger by sucking up air, Carvalho said. “It creates a tornado track, and wherever this goes, the destruction is like any other tornado.”

In 2018, a fire tornado the size of three football fields killed a firefighter as it exploded in what already was a vast and devastating wildfire near near Redding, about 250 miles (400 kilometers) north of San Francisco in northern California. Scientists later described an ice-capped cloud that reached 7 miles (11 km) into the air and caused winds up to 143 mph (230 kph).

Research also suggests fire tornadoes can carry airborne embers, also called firebrands, over long distances, said James Urban, an assistant professor in the Department of Fire Protection Engineering at Worcester Polytechnic Institute. They also can change the fire’s behavior, he said.

“That’s also something that is dangerous and scary for first responders, or really anyone,” he said. “It can change and maybe go in a different direction.”

The interaction between wind, the fire plume and topography determines whether a tornado will develop, he said. For example, sometimes a certain topography will restrict airflow in such a way that a spiral pattern develops.

Can you make one in a lab? Together with San José State University, Worcester Polytech is part of a Wildfire Interdisciplinary Research Center. In the lab in Worcester, researchers have created small fire tornadoes by putting up walls around a fire or arranging a bunch of little fires that together restrict airflow. But that’s on a much smaller scale than what’s happening with the wildfires.

“We’ve got the biggest fire lab in the US for a university, but we cannot get something the size of what’s been reported at these fires,” he said. “You can’t really bottle that and put it in a lab.”
