In the coastal area of Guangdong, slit-less spectra for first return strokes of lightning between the cloud and ground were obtained. After spectrum analysis and line identification were done by using multi-configuration Dirac-Fock (MCDF) method, parameters like wavelengths, oscillator strengths, transition probabilities, and excitation energies were calculated. According to the relative intensities of lines and transition parameters, temperatures for individual lightning strokes and at different heights of the discharge channel were calculated by using multiple-line method.
