But the geological and geochemical analyses showed that there existed a set of high quality marine source rock in the platform slope facies of Middle Ordovician Pingliang Formation. The oil and gas generated from the source rock of Pingliang Formation was accumulated firstly in the central Palaeo-uplift and its surrounding regions. The thermogenic asphalt in palaeo-uplift carbonate reservoir indicated that oil accumulation completed transition from oil to gas in the Lower Crataceous. Along with the palaeo-uplift axis convection and the formation of westward monocline in the Late Crataceous, gas from the palaeo-reservoir was finally accumulated in the weathering crust of Majiagou carbonate reservoir.

The results of cloud image analysis show that the TBB is lower than 230K (-44℃) when the convection grows most prosperously and the area with the brightness temperature difference of lower than -4℃ corresponds to the place where is most affected by the strong thunderstorm. The center of low value with T≤-7℃ corresponds to the strong echo of radar. There is a good correspondence between the strong convective weather and maximum gradient of TBB, which distributes along the moving cloud cluster. The moving path of strong storm is similar to that of the maximum positive gradient of T.
