A Tropical Depression over the South China Sea in June 2025—Observational and Forecasting Aspects
AtmosphereA tropical depression (TD) formed over the northern part of the South China Sea and affected Hong Kong during 25–26 June 2025. Based on the historical database, there were not many TDs following a similar track in the past, namely, a northwestward track ...

Mesocyclone and Microburst Signature Distortion with Dual PRT Radars
Journal of Atmospheric and Oceanic Technology, 2001 Abstract A simple model is used to illustrate the limitations of dual pulse repetition time (PRT) radars for measurements of wind fields with strong horizontal wind gradients. In such conditions, errors may occur even if the radial velocity measurements in the individual rays are not aliased. However, basic circulation and divergent signatures are seen

, 2008 EC only confirmed this as a tornado due to a photo showing a waterspout connected to a convective cloud base. Dave Sills notes that rotation is likely associated with storm outflow as opposed to a mesocyclone. Unusual direction of travel (NE to SW)
