The following web calculator computes rain drop mass based on size and also the raindrop shape and volume. Raindrops with an equivalent diameter of Ø5 mm or larger may be prone to break up into smaller drops as their fall velocity increases. Aerodynamic forces increase with the square of airspeed, while surface tension forces decrease with increasing temperature. Vertical fall speed, in turn, affects its exact shape since the balance of aerodynamic and surface tension forces changes with increasing fall speed and increasing air temperature as the drop nears the ground. Temperature and the amount of air dissolved in rainwater (or dissolved air pollutants) affect each water droplet’s density, which in turn affects its mass and weight and it’s vertical fall speed (velocity). As found in literature, the characteristic raindrop diameter is the theoretical diameter a raindrop would have if it was perfectly spherical with the same exact volume of water as the real non-spherical drop. Raindrops of anything but the smallest sizes (< Ø0.7 mm) are not spherical.
