چکیده
This study aims to analyze the contribution of dry lightning to major wildfire events in Iran’s Zagros region during May 2020 and June 2019. To achieve this, we utilized a combination of satellite-based fire data from FIRMS and lightning data from the Earth Networks Total Lightning Network (ENTLN). In addition, meteorological datasets and reanalysis models were employed to assess drought conditions and fire-conducive weather patterns. Key indices such as the Fire Weather Index (FWI), Fire Danger Index (FDI), Burned Area Index (BI), Keetch–Byram Drought Index (KBDI), and the Standardized Precipitation Evaporation Index (SPEI) were applied. Burn severity was evaluated using Landsat-8 and Sentinel-2 imagery. Our results reveal a strong correlation between wildfire activity and lightning occurrences, particularly in areas with dry vegetation, elevated temperatures, and minimal precipitation. Quantitative validation during two major fire events—June 2019 and May 2020—confirms that wildfires were most intense on days when dry lightning coincided with elevated Fire Weather Index (FWI) values. For instance, June 6 and 7, 2019 recorded 4332 and 4833 dry lightning strikes, FWI values of 33.8 and 39.4, and over 900 high-confidence fire detections each day. Similarly, May 20 and 21, 2020 exhibited peaks in all three factors, with up to 5773 lightning strikes and FWI values exceeding 24. These findings substantiate the synergistic role of dry lightning and fuel flammability in wildfire ignition and highlight the importance of multi-variable monitoring for fire risk assessment.
