Why are there so many thunderstorms in the sea area?

Explain the formation of thunderstorms:

When the temperature rises, the air close to the ground can cause water to vaporize faster due to its higher temperature. (The sea contains a large amount of water, and water vapor will naturally evaporate. More abundant, and water is a poor conductor of heat and can firmly lock heat), causing the density of the air to decrease, the air to become lighter, and the lighter air to rise continuously.

As the altitude increases, the temperature will gradually decrease (for every 100 meters, the temperature decreases by 0.6 degrees), and the air will gradually become cooler. When the air cools, part of the water vapor will liquefy into small water droplets, forming cumulonimbus clouds.

When the small water droplets in the cumulonimbus clouds continue to collide and merge into larger water droplets, they begin to fall, while the hot air rising from the ground rushes upwards, and the two are electrified by friction. Rising air currents are positively charged and falling water droplets are negatively charged. As time goes by, the top of the cumulonimbus cloud accumulates a large amount of positive charge, and the bottom accumulates a lot of negative charge; the sea surface also becomes positively charged due to the induction of the negative charge at the bottom of the cumulonimbus cloud.

The water droplets in the cloud merge and increase in size, until the rising thermal air currents can no longer hold them, and they fall straight from the cloud. The thermal air in the lower layer was hit by the rain and suddenly became colder. It stopped rushing up and instead rushed down to the sea. At this time, the electric charges in the air begin to discharge, and a thunderstorm occurs.
