In different parts of the world, the seasons are different. People all over the world experience different types of weather even though they may be in the same season. For instance, people in China may be having different types of weather like cool weather, but during spring in the United States it may be warmer.
There also may be rain in the United Sates during spring, but tornadoes and heavy wind in another part of the world during spring. Often times, a rainbow is produced in the sky after a rainstorm.
The sun must be shining which doesn’t happen often after a rainstorm, but sometimes it does. During the monsoon season, there is a lot of rain and unusual weather. Therefore, a rainbow would most often be seen during this season.
