Not all meteors enter the atmosphere. Some just graze the surface which makes the meteors train seem longer. Every 33 years this comet becomes visible because the comet is closer to the Earth. During this time there are more meteors than usual. There are sometimes thousands of meteors per hour.
Most meteors are a result of a passing comet.
The heat from the sun causes the comet to melt and particles come off in large volume causing a storm. To observe this meteor shower and if you live close to an urban area, you will need to go to a place where there is less light pollution. Most of the meteors will be dimmer so you may miss seeing the majority of the storm if the area you are viewing them in is too light. Going out to the rural areas or in national or state parks that are away from bright lights are the best for viewing. Make sure you dress accordingly because in a lot of regions November can be very cold.
