The Science and Efficacy of Cloud Seeding in Addressing Air Pollution and Drought

Cloud seeding involves spraying salt mixtures (like silver iodide or calcium chloride) into clouds via aircraft to induce precipitation. Recently, IIT Kanpur conducted trials over Delhi to combat smog, but results were disappointing due to unsuitable cloud conditions. Historically, India's experience with cloud seeding dates back to 1952. A major study, the Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX) (2017-2019), found that seeding could increase rainfall by 18-46% in specific drought-prone regions like Solapur. However, the post-monsoon clouds over Delhi often lack the necessary moisture and quality for successful seeding.

  • Cloud seeding requires specific cloud types with sufficient moisture and 'supercooled' water droplets to be effective.
  • The CAIPEEX experiment (2017-2019) provided scientific evidence that seeding can enhance rainfall in drought-prone areas like Solapur, Maharashtra.

Scientific Mechanisms of Tropical Cyclone Formation, Classification, and Measurement Techniques

Tropical cyclones are powerful weather systems that form over warm tropical waters (above 26.5°C). They require specific conditions: low-pressure areas, sufficient Coriolis force (usually 5 degrees away from the equator), and low vertical wind shear. The 'eye' of the cyclone is a calm center surrounded by the 'eyewall,' where the most intense winds occur. Measurement involves satellite imagery, ocean buoys, and 'hurricane hunters' aircraft. The India Meteorological Department (IMD) classifies these storms based on wind speed, ranging from depressions to super cyclonic storms, using numerical weather models for forecasting.

  • Cyclones derive energy from the evaporation of warm ocean water, intensifying as they move over sea.
  • High vertical wind shear can disrupt a cyclone's structure, preventing it from strengthening into a storm.
  • The Coriolis force, caused by Earth's rotation, is essential for creating the characteristic spiral of a cyclone.
