Gravity wave signatures at mesopause heights
The ALOMAR SOUSY Radar operated at 53.5 MHz has been used in a five-beam configuration to study dynamical processes at gravity wave periods in the summer polar mesosphere. A case study of a gravity wave with a period of about 9 min is presented and analysed in some detail. The three-dimensional wave number vector is determined from the phase information of the 9-min velocity oscillations obtain...
متن کاملMesopause-region temperature and wind measurements with pseudorandom modulation continuous-wave (PMCW) lidar at 589 nm.
A study on the feasibility of using pseudorandom modulation continuous-wave (PMCW) Na lidar for mesopause-region temperature and horizontal wind measurements is presented with a number of specific geometries and associated beam-telescope overlap functions, suitable for ground-based and airborne deployments. The performance of these deployment scenarios is analyzed by scaling from the received s...
متن کاملObservations of gravity wave forcing of the mesopause region during the January 2013 major Sudden Stratospheric Warming
Studies of vertical and interhemispheric coupling during Sudden Stratospheric Warmings (SSWs) suggest that gravity wave (GW) momentum flux divergence plays a key role in forcing the middle atmosphere, although observational validation of GW forcing is limited. We present a whole atmosphere view of zonal winds from the surface to 100 km during the January 2013 major SSW, together with observed G...
متن کاملExtreme Value Analysis of Wave Heights
University of Cantabria Avenida de los Castros s/n, 39005, Santander, Spain This paper discusses the most common problems associated with the determination of design wave heights. It analyzes two common methods used In fitting wave data and shows some of the stability or inconsistency prcAlems associated with commonly used distributions. Some methods to obtain confidence intervals, detecting of...
