Stroke-13, radical-rain, structure-up and down, traditional-thunder, five strokes-FLF, five elements-water, pinyin-léi i.
Writing skills: upper width and lower width. The horizontal painting of Rain is short, and the stippling distance is appropriate and small. "Tian" is wide at the top and narrow at the bottom, with moderate size, and the middle vertical is opposite to the upper vertical. "Thunder" is the answer-1. The rain fell on the fields. 2. Need to leave half (type a Chinese character)
Lightning is a spectacular and somewhat frightening discharge phenomenon accompanied by lightning and thunder. Lightning is usually produced in cumulonimbus clouds with strong convection, so it is often accompanied by strong gusts and heavy rains, and sometimes accompanied by hail and tornadoes.
The top of cumulonimbus clouds is generally very high, up to 20 kilometers, and there are often ice crystals on the top of the clouds.
The attachment of ice crystals, the breaking of water droplets and air convection make clouds generate charges. The distribution of charge in the cloud is complicated, but generally speaking, the upper part of the cloud is dominated by positive charges and the lower part is dominated by negative charges. A potential difference is formed between the upper and lower parts of the cloud.
When the potential difference reaches a certain level, discharge will occur, which is our common lightning phenomenon. The average current of lightning is 30,000 amps, and the maximum current can reach 300,000 amps. The voltage of lightning is very high, about 1 billion to 1 billion volts.
The power of medium-intensity thunderstorm can reach10 million watts, which is equivalent to the output power of a small nuclear power plant.
In the process of discharge, the temperature in the lightning channel suddenly rises, which makes the air volume expand rapidly, thus generating shock waves and leading to strong lightning.
When the charged Lei Yun is close to the protrusions on the ground, a violent discharge will occur between them. There will be strong flash and explosion roar at the scene of lightning discharge. This is the lightning and thunder that people see and hear.
