Water vapor rises to the sky and cools into clouds. When the temperature of the cloud cluster is low, it cools the surrounding water vapor, and the volume of water vapor shrinks, and the surrounding air vapor supplements the space. The water vapor rising below the cloud group rises linearly, and the water vapor molecules shrink smaller and smaller in the rising process, showing a funnel shape. The cooling volume of rising water vapor molecules is shrinking, and the gas molecules under the cloud are constantly replenishing the space, resulting in strong winds. Because the cooling volume of water vapor is shrinking, the gas in the surrounding supply space comes unevenly, forming a tornado.
The formation of tornadoes at sea;
A waterspout can be simply defined as a "water tornado", which usually refers to a non-supercell tornado on the water. The hose will overturn the ship and destroy it. When it lands, it will do more harm and take away life.
Tornadoes are water-absorbing dragons, which are common tornadoes on land. Tornadoes are the flow of air, and air is invisible. The air pressure in the center of the tornado is very attractive. Attract dust, water vapor and other sundries. Due to gravity, liquid water cannot stay in the air for a long time. After the dragon absorbs water, the water sucked into the sky will fall and form a rainstorm, so the so-called dragon suction is a tornado.
Dragon suction is a tornado that occasionally appears over warm water. Its upper end is connected with thunderstorm clouds, and its lower end extends directly to the water surface. The air spins rapidly around the axis of the tornado. Attracted by the extremely low air pressure in the center of the tornado, the water flow is sucked into the bottom of the vortex and then becomes a vortex around the axis.
Tornado, commonly known as "dragon absorbs water", is a strong wind vortex with small range and strong wind force extending from the bottom of thunderstorm cloud to the ground or water surface.
Tornado winds are very strong. Near the tornado center, the horizontal wind speed can reach more than 100 meters per second, and in extreme cases it can reach 300 meters. 12 wind speed is equivalent to more than 30 meters per second, and the damage caused is amazing.
When a whirlwind appears in a river, lake or ocean, a tornado will form. When the cold air mass in the atmosphere passes through the water body, the warm and humid gas rises upward, forming a huge water column. When these water columns pass through the sea surface, they will leave traces of water vapor formation. The diameter of the water column varies from several feet to several hundred feet, and its length exceeds 1 mile (1.6 1 km), and it goes deep into the clouds. Tornadoes at sea are weaker than cyclones, and often only when they cross the land will they pose a threat to people.
