Abstract :
A monostatic acoustic sounder (SODAR) has been developed in the Department of Physics, Sri Venkateswara University, Tirupati, India for the study of dynamical behavior of the atmospheric boundary layer (ABL) phenomena over Tirupati. Short period waves/down-flow is reported. We suggest these short period waves be caused due to onset of nocturnal drainage flows under convection/thermal inversions of variable depth. The stability condition of the atmosphere has great relevance to problems related to air-pollution. Sodar echograms and surface meteorological data facilitate to study stability categories of the boundary layer over Tirupati, India
