BMKG Monitors Atmospheric Dynamics Daily for Weather Modification Operations

The Meteorology, Climatology, and Geophysics Agency (BMKG) in Indonesia is enhancing its atmospheric monitoring to precisely execute weather modification operations (OMC). These operations, ranging from hourly to 10-day predictions, are crucial for artificial rain interventions during the dry season. BMKG Acting Deputy for Meteorology, Andri Ramadhani, emphasized the importance of real-time data for identifying ideal cloud conditions for cloud-seeding. This ensures that salt (NaCl) dispersal effectively produces rain in target zones, preventing waste. The primary goals of these weather engineering efforts are to replenish major reservoirs and combat the dryness of peatland areas highly susceptible to fires. The selection of OMC implementation sites is strategically aligned with regional vulnerabilities, focusing on food production centers facing irrigation shortages and six provinces identified on the forest and land fire disaster alert map. Jambi, a province with critical peat forests, is currently undergoing weather modification operations from June 5 to June 12, 2026, following a declaration of emergency alert status for forest and land fires. The operation, conducted in collaboration with the National Disaster Management Agency (BNPB) and the Indonesian Air Force from Sultan Thaha Airport, has already seen cloud seeding efforts over vulnerable regencies. These efforts have reportedly led to localized rainfall in several affected areas, demonstrating the situational and adaptive approach BMKG takes towards weather modification.

We at the Deputy for Meteorology continuously monitor the current atmospheric dynamics, both on an hourly scale and over the next 10 days. Therefore, what the OMC does is precise, efficient, and of course, always taking into account which areas need immediate action.
