Estimating Vertical Air Motion within Precipitating Clouds Using a Novel Dual-Frequency Radar Method: From Single-Site Validation to Multi-Site Application for an MJO Case Study
Very High Frequency (VHF) atmospheric Doppler radars measure vertical air motion via a Bragg scattering peak, but precipitation introduces a Rayleigh scattering peak that severely biases the vertical air motion estimate downward. The conventional two-peak fitting method is computationally unstable and frequently fail...
