A SCIENCE NOTE: Violent Rain
Mass and velocity are just part of the equation; density also plays a key role. The combination of these variables increases the intensity of flow forces. Wind and water forces scale with the square of velocity, meaning that as flow speeds increase — due to more intense heating or heavier rainfall — the damage scales accordingly. According to drag physics, force is proportional to density times the square of velocity.
For example, a 20-mile-an-hour wind exerts four times the force of a 10-mile-an-hour wind, while a 40-mile-an-hour wind exerts 16 times the force of a 10-mile-an-hour wind. At 50 miles an hour, the force is 25 times greater, and at 60 miles an hour, it’s 36 times greater than at 10 miles an hour. Now, add the density factor: water is about 800 times denser than air, so a 10-mile-an-hour water flow exerts 800 times the force of a 10-mile-an-hour wind.
As flow velocities increase due to climate change, the forces — and thus the damage — scale with the square of the velocities.
The density of H2O changes significantly as it transitions between gas, liquid, and solid phases, governed by molecular arrangement and the forces between water molecules.
This behavior is unusual compared to most substances, as solids are typically denser than their liquid counterparts. Water’s unique properties result from its hydrogen bonding, which has profound implications for Earth’s climate, ecosystems, and life itself.
