Tiivistelmä	The lightning jump is a rapid increase in lightning activity (number of flashes per unit time) that precedes severe weather including hail, heavy rain, and tornadoes. This phenomenon, observed using satellite or ground-based lightning detection networks, is an operational diagnostic tool for real-time severe weather warning.	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.
