Abstract EN
Single Spectrum Bipartite Graph (SSBG) model is developed to forecast thunderstorms over Kolkata (22∘32′N, 88∘20′E) during the premonsoon season (April-May).
The statistical distribution of normal probability is observed for temperature, relative humidity, convective available potential energy (CAPE), and convective inhibition energy (CIN) to quantify the threshold values of the parameters for the prevalence of thunderstorms.
Method of conditional probability is implemented to ascertain the possibilities of the occurrence of thunderstorms within the ranges of the threshold values.
The single spectrum bipartite graph connectivity model developed in this study consists of two sets of vertices; one set includes two time vertices (00UTC, 12UTC) and the other includes four meteorological parameters: temperature, relative humidity, CAPE, and CIN.
Three distinct ranges of maximal eigen values are obtained for the three categories of thunderstorms.
Maximal eigenvalues for severe, ordinary, and no thunderstorm events are observed to be (2.6±0.12), (1.88±0.09), and (1.26±.03), respectively.
The ranges of the threshold values obtained using ten year data (1997–2006) are considered as the reference range and the result is validated with the IMD (India Meteorological Department) observation, Doppler Weather Radar (DWR) Products, and satellite images of 2007.
The result reveals that the model provides 12- to 6-hour forecast (nowcasting) of thunderstorms with 96% to 98% accuracy.
