Is it easy to generate static electricity when the weather is dry in the north?

Yes, it is easier to generate static electricity in dry weather.

When the weather is dry, the possibility of mutual friction and electrification becomes greater, and due to the dry air, the release speed of static electricity generated by friction slows down, thus static electricity accumulation will occur.

However, in wet seasons or regions, static electricity generated by friction will be released quickly, and generally there will be no static electricity accumulation.
