Scientists Discover Hidden Hotspots Where Raindrops Form in Warm Clouds

For generations, the precise birthplace of rainfall within warm clouds has eluded atmospheric science, leaving a quiet but consequential gap in humanity's ability to understand its own climate. Researchers from the Max Planck Institute, hovering a laser-equipped balloon-kite instrument over the Caribbean, have now found that rain does not emerge uniformly from within clouds, but rather from intensely concentrated pockets of droplets smaller than a meter across. This discovery — that the origins of rain are hidden in microscopic hotspots shaped perhaps by turbulence — promises to sharpen the to
