Ascent rainfall mechanism is “one of the most important factors in leading to various rainfall behaviors in different regions, such as various atmospheric precipitation seen in different time scales” (Masoompour, Miri, Zolfaghari, & Yarahmadi, 2013, p.299). In fact, some of them can be called atmospheric phenomena due to their special nature. One of these atmospheric phenomena is thunderstorm. Not only this storm and its accompanying phenomena like lightening, tornado, hail, strong winds, and heavy precipitation (see Changnon, 1925, 2001), but also atmospheric hazard phenomena in aviation, such asturbulence, frost, and wind shear (Tajbakhsh et al., 2009) cause remarkable damage to human and natural environments. Therefore, recognizing the features of these phenomena has been attracting the attention of researchers.
