The atmospheric coupling due to Planetary Waves (PW) in the middle atmosphere (20–90 km) has been studied using TOMS, MetO and MFR data. The wavelet and wave number analyses have been applied to all parameters at five CUJO (Canada US Japan Opportunity) locations. The CUJO network covers latitudes of 31–52 • N and longitudes from 81 • W to 142 • E, and(More)
It is important to obtain the year-to-year trend of stratospheric minor species in the context of global changes. An important example is the trend in global ozone depletion. The purpose of this paper is to report the accuracy and precision of measurements of stratospheric chemical species that are made at our Poker Flat site in Alaska 5 (65 • N, 147 • W).(More)
Planetary and tidal wave activity in the tropopause-lower stratosphere and mesosphere-lower ther-mosphere (MLT) is studied using combinations of ground-based (GB) and satellite instruments (2000–2002). The relatively new MFR (medium frequency radar) at Platteville (40 • N, 105 • W) has provided the opportunity to create an operational network of(More)
Although wall shear stress (WSS) has long been considered a critical indicator of intracranial aneurysm rupture, there is still no definite conclusion as to whether a high or a low WSS results in aneurysm rupture. The reason may be that the effect of WSS direction has not been fully considered. The objectives of this study are to investigate the magnitude(More)
