The dust particles that the combustion of a fire releases into the atmosphere increase in intensity and strength. The authors of the work verified this after analyzing the effect of smoke in a meteorological alteration that on April 27, 2011 caused the formation of 122 tornadoes and caused 313 deaths in the southern United States. On that occasion, the solids contributed by the smoke aggravated the situation, as they caused the cloud base to fall and increased the shear wind, a type of current caused by the difference in speed at different altitudes. The coincidence of both factors increases the probability that tornadoes will be more aggressive.
The experts used computer simulations based on data collected during the fateful day to represent the advance of the smoke and its effects on solar radiation and cloud cover. Currently, meteorological prediction centers do not consider the effect of atmospheric particles, but they should , according to the signatories of the study.
