The impact of severe weather events and lightning in the state is significant, especially to the safety of the general public and also to the activities of the Government of Andhra Pradesh. The Earth Networks Total Lightning Network (ENTLN) have provided APSDMA with detailed forecast information on the location and intensity of both in-cloud (IC) and cloud-to-ground (CG) lightning in real time, thus improving public safety, operational safety and efficiency.
In-cloud lightning comprises of the vast majority of lightning activity in the atmosphere and often serves as a precursor to extreme weather conditions that include heavy rain and hail, high wind and gust fronts, dangerous cloud-to ground lightning strikes and cyclones. Total lightning data enhances situational awareness and enables early and more accurate severe weather warnings within 250 to 500 meters in range and up to 30 to 40 minutes in advance.
The state-of-the-art lightening alerting system set up in the SEOC have a detailed operating procedure to effectively monitor and warn in advance regarding thunderstorms and lightening.
- Once a lightening has happened, within 5 minutes an email notification is received from Earth Networks System which initiates the in depth observation and close monitoring of the activity through a visualization tool on screen. If the intensity of the activity is high, the team of operators follows deterministic process, fill alerting forms and notify SEOC in-charge about the situation. The messages are disseminated in 3 steps.
- The alert messages are then sent through Kaizala mobile application to Tahsildar and concerned Village Revenue Officers (VRO).
- Alert messages are sent through WhatsApp mobile application and social media to Information & Public Relations (I&PR) department to publish in TV channels.
- Telephonic calls are made to Tahsildar and concerned Village Revenue Officers (VRO) directly.
- Once the above steps are completed, the team again goes back to monitoring the intensity of the activity.
