ATMOSPHERIC PRESSURE JUMPS MEASURED WITH ARRAYS OF SENSITIVE PRESSURE SENSORS IN THE VICINITY OF CHICAGO'S O'HARE INTERNATIONAL AIRPORT

An experiment designed to evaluate the use of arrays of sensitive pressure sensors for gust-front detection is described. First results of the experiment (which is still underway at Chicago's O'Hare airport have demonstrated the feasibility of predicting the motion of such density currents by using an array of such sensors. Using data sets obtained in June through August of 1976, implications for the design of arrays to provide warnings of gust front systems in airport environments are discussed. Although over 80% of the pressure jumps over the O'Hare system were tracked, several events went undetected at two or more of the outer array locations. It is therefore concluded that the optimum array density will involve a compromise between practicality and a need for high reliability in detection.
