![]() ![]() As a result, they can exert more force on impact, potentially causing erosion, soil compaction, and surface runoff. ![]() Larger raindrops have a higher terminal velocity, meaning they fall faster than smaller droplets. The size of raindrops affects several aspects of our environment. It’s important to note, however, that such large raindrops are the exception rather than the rule. These exceptionally large raindrops are rare and usually occur in intense thunderstorms or tropical cyclones where strong updrafts can support their growth. This resistance limits the maximum size a raindrop can reach.Īccording to scientific studies and observations, the largest raindrops ever recorded were approximately 8 to 9 millimeters in diameter. As raindrops fall through the atmosphere, they experience air resistance, which tends to flatten and distort their shape. The maximum size that a raindrop can reach is influenced by several factors, including the updrafts within a cloud, the coalescing process, and air resistance. Once a cloud droplet reaches a certain size and becomes heavy enough, gravity causes it to fall as a raindrop. ![]() CCN are tiny particles such as dust, pollutants, or salt crystals that provide a surface for water vapor to condense on. This is where the presence of CCN becomes critical. However, in order to become raindrops, they must cross a critical size threshold. As cloud droplets continue to collide and merge, they grow in size. ![]()
