❓ Frequently Asked Meteorological & Oceanographic Questions (Direct Answers)

Q1. What is the Ramji Weather Channel and what intelligence does it deliver? +

Ramji Weather Channel is an advanced, high-definition meteorological, oceanographic, wave physics, and seismological intelligence portal. It delivers real-time coastal Doppler weather radar, INSAT-3DS geostationary satellite streams, Open-Meteo marine wave dynamics, USGS global earthquake tracking, Central Water Commission (CWC) river discharges, synchronized UTC/IST dual clocks, and Vikram Samvat lunar Panchang coordinates.

Q2. How do I inspect live Doppler radar and satellite feeds for Indian coastal cities? +

Select the Coastal Radar or Satellite tab on the dashboard. Users can inspect live 10-minute Doppler radar loops for Mumbai, Chennai, Visakhapatnam, Kolkata, Goa, and Kochi to track storm cores in dBZ reflectivity. The Geostationary Satellite Studio provides INSAT-3DS color composite (RGB), thermal infrared (IR1 for cloud-top temperatures), visible cloud, and water vapor bands.

Q3. What is Kallakkadal and how does the marine desk warn against coastal swell surges? +

Kallakkadal refers to sudden, intense ocean swell surges along the coasts of Kerala, Tamil Nadu, and Lakshadweep that occur under calm, sunny local skies. They are generated by distant Southern Ocean / Antarctic storms thousands of nautical miles away. Ramji Weather Channel tracks long-period swells (> 18 seconds) and significant wave height ($H_s$), alerting harbor pilots and coastal communities before surges breach low-lying coastal sea walls.

Q4. How does Ramji Weather Channel evaluate Himalayan seismic gaps and earthquake risks? +

The platform ingests live telemetry from the USGS Global Earthquake Hazards Program and National Centre for Seismology (NCS). Epicenter coordinates are plotted in real time on an interactive Leaflet world map alongside a Magnitude vs. Focal Depth subduction scatter chart. The portal specifically highlights the Himalayan Central Seismic Gap, Zone V (Jammu & Kashmir, Himachal, Uttarakhand, Northeast) and Zone IV (Delhi-NCR) tectonic fault lines.

Q5. How does the dual chronometer and astronomical Vedic Panchang algorithm work? +

The dual chronometer synchronizes local Indian Standard Time (IST UTC+05:30) and Universal Scientific Coordinated Time (UTC Zulu Z) with millisecond precision. Concurrently, an astronomical algorithm computes the synodic lunar phase from known reference epochs to display the real-time Vikram Samvat year, lunar month (Masa), Paksha (Shukla/Krishna), and active Tithi (Pratipada to Purnima/Amavasya), crucial for evaluating gravitational spring tides.
