Sporadic Ca and Ca layers at mid-latitudes: Simultaneous observations and implications for their formation
We report on the observations of 188 sporadic layers of either Ca atoms and/or Ca ions that we have observed during 112 nights of lidar soundings of Ca, and 58 nights of Ca soundings, at Kühlungsborn, Germany (54N, 12E). The Ca soundings have been performed simultaneously and in a common volume with the Ca soundings by two separate lidars. Correlations between sporadic neutral and ionized metal...
متن کاملRadio tomographic imaging of sporadic-E layers during SEEK-2
During the SEEK-2 Rocket Campaign in August 2002, a Dual Band Beacon (DBB) transmitting to Ground Receivers provided unique data on E-Region electron densities. Information from two rocket beacons and four ground receivers yielded multiple samples of E-region horizontal and vertical variations. The radio beacon measurements were made at four sites (Uchinoura, Tarumizu, Tanegashima, Takazaki) in...
متن کاملTerdiurnal signatures in sporadic E layers at midlatitudes
Global Positioning System radio occultation measurements by the FORMOsa SATellite mission3/Constellation Observing System for Meteorology, Ionosphere and Climate satellites were used to analyse the behaviour of the signature of the terdiurnal tide in sporadic E (ES) layers at midlatitudes (43–63 N). According to theory, the occurrence of ES is expected when the vertical zonal wind shear, which ...
متن کاملFinger Formation in Biofilm Layers
A simple single substrate limiting model of a growing biofilm layer is presented. One-dimensional moving front solutions are analyzed. Under certain conditions these solutions are shown to be linearly unstable to fingering instabilities. Scaling laws for the biofilm growth rate and length scale are derived. The nonlinear evolution of the fingering instabilities is tracked numerically using a le...
متن کاملGiant aneurysm formation in sporadic renal angiomyolipoma.
Angiomyolipomas are the most common mesenchymal renal neoplasms. Two types have been described: (i) sporadic angiomyolipoma and (ii) angiomyolipoma associated with tuberous sclerosis. Giant aneurysm formation is usually noted in angiomyolipomas associated with tuberous sclerosis and is rare in sporadic variety. Tumor diameter and aneurysm diameter have been used as predictors of rupture. We rep...
