Middle atmospheric dynamics through Lidar soundings: a few case studies

Rayleigh lidar measurements taken during a campaign over/Frascati (42/spl deg/N, 13/spl deg/E) are analyzed to realize system dynamics during instabilities and also layer responses towards propagating waves. Instabilities in the system are studied by characterizing parameters defined by variabilities like temperature etc.. The paper discusses variations of Burnt frequency and temperature gradient for few noctural cases and studies situations when the static stability of stratosphere is observed to be lost. A few cases of wave propagation from stratosphere to mesosphere are discussed during this condition. Vertical structures of the waves are estimated from cross correlation parameters.<
