Lightning threat indicator

The solution takes advantage of information about the increase of electric charge of water droplets in a cloud, which is obtained by measuring the characteristics of electromagnetic radiation backscattered by a cloud at two wavelengths. The electric charge monitoring system uses a simple principle in which electrically charged particles with dimensions at least 100 times smaller than the wavelength of the radar signal scatter electromagnetic waves with altered efficiency.

Competitive advantage

  • prediction capability independent of droplet morphology (the technology is based on optical properties);
  • prediction capability independent of external factors such as wind shear.

Use of technology

  • applied meteorology, mainly the use of information about the state of electric charge of water droplets to indicate the lightning threat for various applications (e.g. in operation of airports).
