What are the strange natural phenomena in nature?

Northern lights, milky clouds, red tides, whale landings, tornadoes.

1, Northern Lights

Since people discovered the Northern Lights, they have been deeply attracted by its mystery and beauty. The Northern Lights usually occur when the sun releases high-energy charged particles, which are released from space at a speed of 300- 1200 km per second. The cloud structure formed by these charged particles is called plasma region.

2. Breast milk cloud

Mammary cloud, also known as breast cumulus, is a cloud with many bags hanging down from the bottom. They are mainly composed of ice, which can extend for hundreds of miles in any direction. However, some breast cloud structures can remain still for 10- 15 minutes. Whenever clouds appear on the chest, it indicates the coming of bad weather. This is usually a precursor to storms or other bad weather.

3. Red tide

Red tide is the rapid accumulation of algae in estuaries, oceans or fresh water, covering the whole sea area or beach and turning the sea water red. This phenomenon is due to the formation of dense visible phytoplankton groups on the water surface.

Although some phytoplankton are harmless, some phytoplankton are highly toxic, which will lead to the death of fish, birds and marine mammals. In some cases, even human beings will be harmed by red tides, although there is no record of death.

4. Whales fall

The phenomenon that whales sink into the sea after death is called whale landing. When a whale dies in the ocean, its body finally sinks to the bottom of the sea. Biologists have given this process a name: whale falling. The carcass of a whale can support the decomposer's circulatory system for hundreds of years.

5. fire tornado

Fire tornado, also known as fire monster or fire whirlwind, is a rare flame phenomenon under some special conditions. Usually, it is mainly affected by gas temperature and gas flow, forming a vertical vortex or vertical radial rotating column similar to tornado effect. Usually, fire tornadoes occur in jungle fires. Vertical vortex is formed under specific air flow and temperature conditions.

A fire tornado can be 30 to 200 feet high and 65,438+00 feet in diameter, but it can only last for a few minutes. If the wind is strong, the fire tornado may last longer.
