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.
Thunderstorms happen when two air masses (hot air and cold air) collide. As it gets later in the day the sun in not at an angle where the it is heating up the air as much thus creating cooler air. When the cooler air hits the warmer air the chance of a thunderstorm occurs.
