Підсумок	The Velocity-Azimuth Display (VAD) is a radar analysis technique that extracts the radial velocity of wind at a constant altitude as a function of azimuth angle around the radar. By fitting a sinusoidal pattern to these measurements, VAD retrieves the mean wind speed and direction at that altitude, providing wind profiles without requiring multiple radar observations.	Dual-polarization (dual-pol) radar is a weather radar system that transmits and receives electromagnetic waves in both horizontal and vertical polarizations simultaneously. This technique, operational in weather services since the 2010s, provides detailed information about precipitation particle type, shape, and size distribution, enabling improved rainfall estimates and better discrimination of hail, rain, and snow.	The Weather Research and Forecasting (WRF) model is a mesoscale atmospheric simulation system used for weather forecasting, research, and climate applications. Developed cooperatively by NCAR, NOAA, and academic institutions, WRF became operational in 2004 and has become one of the most widely used atmospheric models worldwide.
