Abstract: Severe weather often emanates from thunderstorms that have persistent, well organized, rotating updrafts. These rotating updrafts, which are generally referred to as mesocyclones, appear as couplets of incoming and outgoing ...

Abstract: A new and improved algorithm for automatic mesocyclone detection is presented and tested on 23 mesocyclonic storms. A small false-alarm rate (4%) and high probability of detection (83%) are achieved for mesocyclone ...

Abstract: A significant improvement in the reliability and timeliness of tornado warnings can be achieved through quantitative measurement by Doppler radar of selected mesocyclone features. The mesocyclone, a midsize circulation ...

Abstract: A kinematic mesocyclone model is developed to better approximate mesocyclone flows observed by single-Doppler radar. The model is described by two general flow regimes: an inner core region where velocity varies directly ...

Abstract: Future high-altitude laser systems may be affected by cirrus clouds. Laser transmission models were applied to measured and retrieved cirrus properties to determine cirrus impact on power incident on a target or receiver. ...
