Short summary
We advanced the Lightning Differential Space (LDS) method, which maps time and distance between lightning strokes, and demonstrated its use across three distinct meteorological regions. By comparing stroke strength and timing, our new Current Ratio approach reveals flash initiation patterns in different storm types. The method is straightforward and data-driven, enabling physical insight without model-based analysis or prior assumptions, and supports regional lightning analysis and forecasting.
