The unbalanced flow diagnostics and ducting analysis serves a dual purpose of refining the predicted area for mesoscale gravity wave activity and establishing a "confidence level" (an increased probability of significant and long-lasting wave activity when all the test results are positive). Having been alerted to the likelihood of a gravity wave event, the forecaster should look to an automated gravity wave detection system which incorporates digital, high temporal resolution data from ASOS. The availability of this data is a very important factor in determining whether operational gravity wave detection is feasible.
