Causes of thunder in Leizhou Island

1, Leizhou Peninsula is located in the uplift area of the upper mantle, and the crust of the upper mantle is only 24 kilometers thick. Most of the surface rocks are basaltic volcanic rocks rich in iron. Iron is a magnetic substance, and the electromagnetic field is relatively strong in areas rich in iron. The motion friction of matter in air produces positive and negative charges. When negatively charged clouds approach the ground downwards, the protrusions and metals on the ground will be induced to be positively charged. With the gradual enhancement of the electric field, Lei Yun will form a downward guide, and objects on the ground will form an upward flash, and the two will meet to form a discharge to the ground.

2. Leizhou Peninsula is located in the northern tropical low latitude area, with long period of high temperature and high humidity all the year round, abundant heat, surrounded by the sea on three sides, abundant water vapor, complex terrain, low platform, close to sea level, and often in a wet and unstable state, which is easy to produce strong cumulonimbus clouds. The gap caused by the land-sea boundary is conducive to triggering strong convection and releasing unstable energy in the air.

3. Therefore, the special geographical features of Leizhou Peninsula and its adjacent waters provide thermal conditions for the upward movement of strong convective weather, and the special geology makes the thunderstorm weather in Leizhou Peninsula frequent.
