Short summary
Short summary
El Niño and La Niña, the warming and cooling cycle of the tropical Pacific, change wildfire smoke around the world, but not everywhere at once. Using 46 years of global atmospheric data, we found that soot from fires rises almost immediately in Southeast Asia, about five months later in Central America, and seven to eight months later in the Amazon, a timing that held across decades. Because these Pacific events can be seen developing, smoke there could be anticipated months ahead.

Short summary
This study explores how aerosols affect atmospheric heating over African easterly waves (AEWs). Using data from NASA's aircraft and outputs of reanalysis models, the research focuses on days with both Saharan dust and AEWs. Using a radiative transfer model, the study reveals significant differences in heating rates, emphasizing challenges in accurately representing aerosol effects in the atmosphere and underscoring the need for improved aerosol representation in weather models.
