A study of thermal plumes over Tirupati using sodar and microbarograph

An acoustic sounder is designed and developed for the study of the atmospheric boundary layer operating at a frequency of 2.2 kHz and a probing range of 1 km. The infrasonic pressure variations have been recorded using a microbarograph. Simultaneous study of sodar echograms and microbarograph are able to detect the thermal plumes in the boundary layer. In addition, sodar and microbarograph data are seen to correlate well to study the thermal plume activity in the atmospheric boundary layer.<
