Short summary
Kelvin-Helmholtz billows (KHB) have been investigated in the Atmospheric Boundary layer (ABL) using Mono-static SODAR (Sound Detection And Ranging) first time over the capital region Delhi of India. About ninety cases of KHBs observed in SODAR echograms from March 2019 to November 2019 in the ABL. KH billows are a primary cause of mixing in stably stratified conditions and hence have been studied widely by researchers by using ground-based and remote sensing methods.

Abstract. Kelvin-Helmholtz billows (KHB) have been investigated in the Atmospheric Boundary layer (ABL) using Mono-static SODAR (Sound Detection And Ranging) designed and developed by CSIR-National Physical Laboratory, New Delhi over the capital region Delhi of India. KH billows are a primary cause of mixing in stably stratified conditions and hence have been studied widely by researchers by using ground-based and remote sensing methods. About ninety cases of KHBs observed in SODAR echograms from March 2019 to November 2019 in the ABL. Trains of K-H billows lasting from thirty minutes to various minutes were frequently detected in the lower portion of the troposphere (ABL), creating in a statically stable ABL. Most recognised billows are round the resolution limit of SODAR. Additionally, several of the cases contain billows with extremely varied amplitudes and shapes. The most significant number of episodes observed in the October months were related with the morning growth of the inversion.
