A two-stage cascaded prediction framework for urban inundation depth using a dual-branch CNN-ConvLSTM network

Study region Shenzhen, China, is a densely urbanized subtropical megacity characterized by extensive impervious surfaces, rapid runoff responses, and frequent rainfall-induced inundation. Study focus To address the underestimation of urban inundation depth driven by severe zero-i...

Advancing boundary-layer physics via Doppler wind LiDAR dynamic-thermodynamic profiling

Simultaneous, high-resolution measurements of boundary-layer dynamics and thermodynamics remain a longstanding observational challenge. We present a Doppler wind LiDAR–based retrieval that derives virtual potential temperature from TKE-budget buoyancy residuals, enabling concurre...
