Abstract In this study, a total of 339 mesoscale convective systems (MCSs) are obtained in North China using the temperature brightness blackbody (TBB) data from FY-2E warm season 2010 to 2018. The number meso-α-scale (MαCSs) is much more than that meso-β-scale (MβCSs). elongated (MECSs) circular (MCCSs). Most MCSs occur July and August, which have widest influence range, longest duration, stro...
