What are the natural phenomena in nature?

Mammary cloud, also known as cumulus mammalis, is composed of numerous baggy cloud structures at the bottom of the cloud. It is mainly made of ice and can extend for hundreds of miles in any direction. However, some breast cloud structures can remain still for 10- 15 minutes. Whenever milky white clouds appear, it indicates the arrival of bad weather, which is often a precursor to storms or other bad weather.

(2) Red tide

Red tide is the rapid accumulation of algae in estuaries, oceans or fresh water, covering the whole sea area or beach, turning seawater into blood red. This phenomenon is due to the high-density phytoplankton gathering on the water surface to form a dense and visible mass structure. Although some phytoplankton are harmless, some phytoplankton are highly toxic, causing the death of fish, birds and marine mammals. In some cases, even human beings will be harmed by red tides, although no one has ever died in them.

(3) melting icicles

Melting icicles look very much like ice spears, mainly in alpine glaciers, and their sizes vary from a few centimeters high to 5 meters high. At first, the sun shines on the surface of snow or alpine glaciers and melts, forming irregular dents. Once dimples like this are formed, the sun's rays will be reflected in the dimples, increasing the sublimation of local substances. With the gradual deepening of micro-depressions, deep grooves are formed, and finally the ice spear structure is formed.

(4) Northern Lights

There is no doubt that the Northern Lights is one of the most beautiful scenery on earth. Since people discovered it, they have been deeply attracted by the mystery and beauty of this phenomenon. 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.

(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 airflow, forming a vertical vortex or vertical radial rotating gas column similar to tornado effect. Generally, fire tornado usually occurs in the jungle flame, and forms a vertical vortex fire column under specific air flow and temperature conditions. Fire tornado can be 30-200 feet high and 10 feet in diameter, but it will only last for a few minutes. If the wind speed is high, fire tornado may last longer.
