'lightning_potential_index', usually abbreviated to LPI, is an index calculated for improvement of the lightning forecast from atmosphere_convective_available_potential_energy, air temperature at 850 hPa, atmosphere_mass_content_of_cloud_liquid_water, relative_humidity at -10°C, air_equivalent_potential _temperature lapse rates and lifted index.

The lightning_potential_index is a measure of the potential for charge generation and separation that leads to lightning flashes in convective thunderstorms. The index is derived from the convective available potential energy (CAPE), Lifted Index, Theta-E lapse rates, 850 mb temperature, precipitable water and relative humidity at -10 degrees.

The lightning_potential_index is a measure of the potential for charge generation and separation that leads to lightning flashes in convective thunderstorms. It is derived from the model simulated grid-scale updraft velocity and the mass mixing-ratios of liquid water, cloud ice, snow, and graupel.
