Massive Australian fires could actually alter global weather too—here's how:
found that the smoke plumes from towering smoke-laden clouds can penetrate into the stratosphere. Using the 2017 fires in the Pacific Northwest, they found from modeling studies that the smoke aerosols can linger in the stratosphere up to 5 months and actually create net warming at the top of atmosphere. Smoke contains soot, an effective of absorber of solar radiation.
Volcanic aerosols injected into the stratosphere tend to be more sulfate-based, which are more effective scatterers of solar energy.Radiative forcing is a very important aspect of our weather-climate system. I also find it to be one of the most confusing concepts for some people. Many people understand that the Sun is critical in our weather-climate engine, yet in terms of Earth’s climate forcing, it has a “seat at the table” with Greenhouse Gases, aerosols, clouds, and land use change .
Earth is continually bathed in energy from the sun. A portion of the energy that arrives at Earth is reflected back into space, another portion is absorbed directly by the atmosphere, and the remainder moves through the atmosphere to the surface. Sunlight energy heats land and water at the surface, and in turn, they emit heat. This heat provides further warming of the atmosphere.
