The effect of polarization on radar detection of lightning

Geophysical Research Letters, 1982
The polarization dependence of lightning echoes received with a 23‐cm wavelength radar is estimated theoretically and experimentally. The reduction in the lightning radar cross‐section due to the transmission of circular polarization instead of linear is measured to be about 4 dB and is much smaller than the 15‐30 dB reduction in reflectivity of weak ...

An Analysis of Lightning Activity in the Säntis Region through the Big Hiatus in Global Warming [PDF]

The response of local lightning to local surface temperature is examined near the Säntis mountain (2502 m ASL) in the eastern Swiss Alps during the first of the two hiatuses in global warming covering the time periods 1940-1972 and 1998-2014.

Management of Absent Upper Esophageal Sphincter Opening After Neurological Injury

The Laryngoscope, EarlyView.
This study evaluated the effects of swallowing therapy and cricopharyngeus (CP) muscle surgery on upper esophageal sphincter (UES) opening, oral intake, and airway protection in patients with absent UES opening following neurological injury. CP‐targeted surgeries were associated with improved bolus passage and oral intake, but persistent aspiration ...
