Accurate nowcasting of convective clouds from satellite imagery is essential for mitigating the impacts meteorological disasters, especially in developing countries and remote regions with limited ground-based observations. Recent advances deep learning have shown promise video prediction; however, existing models frequently produce blurry results exhibit reduced accuracy when forecasting physical fields. Here, we introduce SATcast, a diffusion model that leverages cascade architecture...
In situ aircraft observations in typhoons have been scarce. This paper documents and analyses the dropsonde data collected Super Typhoon Saola (2023) over northern part of South China Sea. The wind turbulence structures typhoon are investigated. intensities quantified terms turbulent kinetic energy (TKE) eddy dissipate rate (EDR), these compared with other available estimates intensities, such as those based on weather radars, meteorological satellites, numerical prediction (NWP) models. It...
Apart from headwind changes, crosswind changes may be hazardous to aircraft operation. This paper presents two cases of recently observed the range height indicator scans ground-based remote sensing meteorological equipment, namely an X-band microwave radar and a short-range LIDAR. Both instruments have resolution down around 30 m, allowing study fine-scale details vertical profiles cross-mountain airflow at Hong Kong International Airport. Rapidly evolving winds been by equipment in...
