Silicon chemistry in the mesosphere and lower thermosphere
Silicon is one of the most abundant elements in cosmic dust, and meteoric ablation injects a significant amount of Si into the atmosphere above 80 km. In this study, a new model for silicon chemistry in the mesosphere/lower thermosphere is described, based on recent laboratory kinetic studies of Si, SiO, SiO2, and Si+. Electronic structure calculations and statistical rate theory are used to sh...
متن کاملObservations of the 5day wave in the mesosphere and lower thermosphere
The 5-day planetary wave has been detected in the winds measured by the High Resolution Doppler Imager (HRDI) on the Upper Atmosphere Research Satellite (UARS) in the mesosphere and lower thermosphere (50-110 kin). The appearances of the 5-day wave are transient, with a lifetime of 10-20 days in the two-year data set. The structures of selected 5-day wave events are in generally good agreement ...
متن کاملMean winds of the mesosphere and lower thermosphere at 52N in the period 1988–2000
A meteor radar in the UK (near 52 N) has been used to measure the mean winds of the mesosphere/lowerthermosphere (MLT) region over the period 1988–2000. The seasonal course and interannual variability is characterised and comparisons are made with a number of models. Annual mean wind trends were found to be +0.37 ms−1 yr−1 for the zonal component and +0.157 ms−1 yr−1 for the meridional componen...
متن کاملThe 16-day planetary wave in the mesosphere and lower thermosphere
A meteor radar located at Sheeld in the UK has been used to measure wind oscillations with periods in the range 10±28 days in the mesosphere/lowerthermosphere region at 53.5°N, 3.9°W from January 1990 to August 1994. The data reveal a motion ®eld in which wave activity occurs over a range of frequencies and in episodes generally lasting for less than two months. A seasonal cycle is apparent in...
