The Hurricane Hunters took the following measurements from a hurricane over several days as it developed: They found that the air pressure and wind speed are related in the following way: y=-1.11x+ 1140 where x is the air pressure in millibars (kPa) and y is the maximum sustained wind speed in knots (nautical miles per hour).
