Surface air temperature is the temperature of the air around us, generally measured at a height of around two meters (about 6 and a half feet) above the surface. Enter temperature and wind speed to compute wind chill. I hypothesized that as the barometric pressure increased the wind velocity would decrease which my plot showed. The wind speeds varied from 0 to 45 miles per hour with many outliers and the barometric pressure varied from 29.4 to30.8 inches with many outliers. Few other natural disasters cause destruction comparable to the destructive force of a hurricane. Is based on a human face model Incorporates heat transfer theory based on heat loss from the body to its surroundings, during cold and breezy/windy days Lowers the calm wind threshold to 3 mph Uses a consistent standard for skin tissue resistance Assumes no impact from the sun, i.e., clear night sky. The readings measured air pressure in inches. By conducting this science experiment I wanted to find the correlation between barometric pressure and wind velocity. Whilewind speedandair pressuremay seem to be unrelated properties of air, they are in fact one and the same property for all fluids, including air and water. This controls the wind speed of a wind that moves from a high to a low because of diffusion. The lower the barometric pressure at the center of the storm, the stronger the hurricane, and vice versa. Saffir-Simpson Hurricane Scale With the atmosphere trying to balance temperature, pressure and wind there are different sorts of air, known as air masses, circulating around the Earth. First, I recorded the date, time, and barometer readings that I got off the Internet web site, Weather.com in my data log.
