Wildfire smoke can travel long distances, affecting the air quality far beyond the immediate vicinity of the fire. The stronger the wildfire, the higher the smoke reaches in the atmosphere, and the further it can travel. In some cases, smoke can reach over 5 miles above the Earth's surface into the stratosphere. Carried by prevailing winds, it can cover hundreds, or even thousands, of miles. In 2019, smoke from forest fires in Alberta, Canada, was tracked spreading across the Atlantic and into Europe.

What You'll Learn
Wildfire smoke can travel across continents and oceans
Wildfire smoke can travel long distances, extending far beyond the immediate fire zone. Carried by prevailing winds, it can cover hundreds or even thousands of miles. In 2019, smoke from forest fires in Alberta, Canada, was tracked spreading across the Atlantic and into Europe. It has also been known to spread from Australia to New Zealand, and even to South America.
The impact of wildfire smoke on health can be significant. Wildfire smoke contains many pollutants, including tiny particles that can get into your lungs and even your bloodstream. Globally, it has been estimated to cause over 339,000 premature deaths a year.
The distance wildfire smoke travels depends on the wind pattern and atmospheric conditions. The smoke's fine particles are picked up by the wind, lifted into the atmosphere, and pushed into surrounding areas. The height the smoke reaches depends on various factors, such as the strength of the fire, weather conditions, and the surrounding terrain.

The smoke can reach over 5 miles above the Earth's surface
The smoke from wildfires can reach over 5 miles above the Earth's surface. The stronger the wildfire, the higher the smoke reaches into the atmosphere. In some cases, smoke can form an explosive storm cloud called Pyrocumulonimbus, which can launch smoke even higher, reaching the stratosphere.
Wildfire smoke can travel long distances, extending far beyond the immediate fire zone. Carried by prevailing winds, it can cover hundreds, or even thousands, of miles. This means that even if a community is not close to a wildfire, it may still be exposed to its smoke. For example, in 2023, smoke from wildfires in Canada spread along the eastern coast of the US, prompting officials to issue air quality warnings in places including New York, North Carolina, and Ohio. Similarly, in 2019, smoke from forest fires in Alberta, Canada, was tracked spreading across the Atlantic and into Europe.

It can be carried by wind and reach areas far beyond the fire zone
Wildfire smoke can travel long distances, far beyond the immediate fire zone. The smoke can be carried by wind, covering hundreds or even thousands of miles. The stronger the wildfire, the higher the smoke reaches in the atmosphere, and the further it can travel. In some cases, smoke from wildfires can reach the stratosphere, over 5 miles above the surface of the Earth.
In 2019, smoke from forest fires in Alberta, Canada, was tracked spreading across the Atlantic and into Europe. It has also been known to spread across continents and oceans, reaching as far as South America. In 2023, smoke from wildfires in Canada spread along the eastern coast of the US, prompting air quality warnings in places including New York, North Carolina, and Ohio.
The impact of wildfire smoke on health can be significant, and the spread of smoke may be exacerbating the harmful health effects of existing air pollution in busy, overpopulated cities. Wildfire smoke contains many pollutants, including tiny particles that can get into your lungs and even your bloodstream.

The smoke can impact air quality and cause health issues
The smoke from fires can impact air quality and cause health issues. Wildfire smoke can travel long distances, far beyond the immediate vicinity of the fire. In 2023, smoke from wildfires in Canada spread along the eastern coast of the US, prompting air quality warnings in places including New York, North Carolina, and Ohio. In 2019, smoke from forest fires in Alberta, Canada, was tracked spreading across the Atlantic and into Europe. The smoke even made it to South America.
The smoke can travel so far due to the fine particles that are picked up by the wind and lifted into the atmosphere. The stronger the wildfire, the higher the smoke reaches in the atmosphere, and the farther it can travel. In some cases, this smoke can form an explosive storm cloud called Pyrocumulonimbus, which can launch smoke over 5 miles above the surface of the earth into the stratosphere.

The smoke can be carried by explosive storm clouds
The smoke from a fire can be carried by explosive storm clouds, known as Pyrocumulonimbus clouds, which can launch smoke five miles above the surface of the Earth into the stratosphere. Pyrocumulonimbus clouds are formed when large amounts of smoke are launched into the air by a wildfire. The stronger the wildfire, the higher the smoke reaches in the atmosphere, and the further it can travel.
In 2019, smoke from forest fires in Alberta, Canada, was tracked spreading across the Atlantic and into Europe. Smoke from the Australian fires was carried by Pyrocumulonimbus events over New Zealand, where it impacted air quality and visibly darkened snow on mountains. The smoke even made it to South America.
Wildfire smoke can travel long distances, extending far beyond the immediate fire zone. Carried by prevailing winds, it can cover hundreds, or even thousands, of miles. This means that even if a community is not close to a wildfire, it may still be exposed to its smoke. The impact of wildfire smoke on health can be significant, but understanding how smoke moves can help individuals know what to expect.

Frequently asked questions
Fire-polluted air can travel huge distances, even across continents and oceans. In 2019, smoke from forest fires in Canada was tracked spreading across the Atlantic and into Europe.
Fire-polluted air can reach the troposphere, the lowest part of the atmosphere where thunderstorms form. In some cases, it can reach the stratosphere, the layer above the troposphere.
The height fire-polluted air can reach depends on various factors, including the strength of the fire, weather conditions, and the surrounding terrain.
Fire-polluted air can have significant impacts on human health. It contains many pollutants, including tiny particles that can get into your lungs and even your bloodstream. Globally, wildfire smoke has been estimated to cause over 339,000 premature deaths a year.
Understanding how smoke moves can help individuals know what to expect and take appropriate precautions. In areas affected by wildfire smoke, officials may issue air quality warnings and advise residents on how to protect themselves.
