Drizzle is a meteorological precipitation phenomenon characterized by very small, uniform water droplets, typically less than 0.5 mm in diameter, that fall from low stratus or stratocumulus clouds. It forms in shallow, stable cloud layers where collision–coalescence processes are weak but sufficient to produce liquid droplets that can overcome updrafts and reach the surface. Drizzle is associated with high relative humidity, low cloud bases, and weak vertical motions, often leading to reduced visibility and persistent, low-intensity liquid water flux. It plays a significant role in boundary-layer thermodynamics, cloud–aerosol interactions, and surface energy and moisture budgets.
In a quiet laboratory, a team of atmospheric scientists and engineers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory recently gathered around a workstation to watch as little floating speckles, illuminated ...

Climate change enhances extreme rains more than the ordinary drizzle. New research shows that frontal rain increases the most, and illustrates why extreme rains caused by other phenomena are not equally affected.

Such was Sao Paulo's reputation for "garoa"—a fine evening drizzle caused by damp air from the nearby coast colliding with the city's cool climes—that famous singer Caetana Veloso waxed lyrical about it in his 1978 hit

We've all been there—caught outside without an umbrella as the sky opens up. Whether it's a light drizzle or a heavy downpour, instinct tells us that running will minimize how wet we get. But is that really true? Let's take ...
