Wildfires in Australia create a smoke cloud larger than the continental United States! It can be seen from space as it circles the hemisphere, covering over 12.000km! Full animation included.

We are witnessing one of the most devastating fire seasons in Australia. The fires have gotten so intense, that the smoke cloud can be seen from space, as it is circling the South Hemisphere! The wildfires are a result of an unusually hot and dry summer, and it does not seem to be ending soon. 

The large smoke cloud from the fires has reached New Zealand, coloring the sky into yellow hues. The fires are intense enough to cumulate the smoke into a single dense cloud, which is carried east by the prevailing winds. The image below from NASA SuomiNPP satellite shows the fire hotspots in east Australia and the large smoke clouds moving east over New Zealand, which can be easily seen from space. 

Using the atmospheric models, we can predict the winds in the atmosphere and the trajectory of these smoke clouds. One such model which does this by default is the GEOS-5 model from NASA. It calculates the density of black carbon, which is essentially a product from burning fossil fuels and biomass like forests. Black carbon particles are very small and light and travel easily along with the winds, so we can nicely model the movement of the smoke clouds.

On the images below, we can see the sequence of the developing smoke cloud as it travels across the South Pacific, reaching South America in less than a week. The concentrations slowly reduce as it travels across the ocean, but the cloud is dense enough to survive all the way to the Atlantic ocean.

The full high-resolution animation sequence below, shows the scary extent of the fires and the large smoke clouds that are being generated. The total size of the smoke cloud that travels across the hemisphere is larger than the area of the continental United States. The cloud easily travels over 12.000km in distance, into the Atlantic Ocean, before it reduces in concentration and is slowly dispelled by the wind currents.
