Instruments and Available Internet-Based Data for Documenting Weather Conditions

摘要

It has been previously documented that various weather conditions such as wind direction and speed, cloud cover and, especially, temperature inversions can significantly affect the overpressure generated by a blast event (Siskind et al, 1980; Oriard, 1999; Siskind, 2000). The overpressure can be magnified down-wind and reduced upwind;a change in the regular profile of temperature with elevation can magnify or focus the sound intensity at some distance from the blast event.
