Body Mass Index (BMI). BMI stands for Body Mass Index. It is a measure of body composition. BMI is calculated by taking a person's weight and dividing by their height squared. For instance, if your height is 1.82 meters, the divisor of the calculation will be (1.82 * 1.82) = 3.3124.
Dissipating Stage: When the downdrafts encompass the storm, the updrafts are shut off and the storm begins to die. The intensity of the rain decreases. Prior to the development of a thunderstorm, the air near the surface is often warm and moist. With the downdrafts come cool air and the temperature at the surface drops.
How Hail Forms. Within these thunderstorms, very fast currents of air move upwards (called updrafts) and downwards (called downdrafts). Inside the updrafts, water vapor (which is a gas) and rain (which is liquid) are pushed extremely high into the cumulonimbus cloud.
