Source field, and hence an accurate prediction of the surface pressure, particularly near. The trailing edge, is indicative of the quality of the flow solution for far-fie.
Near field the near field of a source is the region close to a source where the sound pressure and acoustic particle velocity are not in phase. In this region the sound field does not decrease by 6 db each time the distance from the source is increased (as it does in the far field).
Weather over the north atlantic is largely determined by large-scale wind currents and air masses emanating from north america. Near iceland, atmospheric pressure tends to be low, and air flows in a counterclockwise direction.
