What does Dongguan Dragon Absorb Water mean?

Dragon water absorption generally refers to tornado (weather phenomenon).

Tornado is a vertical hollow rotating airflow between the bottom of cumulus and the underlying surface, and it is a disastrous weather phenomenon at local scale. Tornadoes can be found in tropical and temperate regions, including the interior of the United States, western Australia and northeastern India. Tornadoes are seasonally weak, and can occur in spring, summer and autumn.

Tornado is a form of concentrated release of unstable energy in a small area near the ground. There is no clear conclusion about the formation of tornado in atmospheric microphysics. But it is considered to be related to updraft and vertical wind shear in dynamics, which can be roughly divided into four stages:

Convection system brings unstable energy in the atmosphere and causes updraft.

The updraft generates vertical vorticity under the action of wind speed and wind direction shear, that is, it begins to rotate in the horizontal direction.

Under the action of convergent airflow, the rotating system developed into a convection system, forming a tornado core in the middle troposphere.

Under the action of downdraft at the front of the convection system, the vortex developed by the tornado core extends to the underlying surface, and the ground air pressure drops sharply, and the ground wind speed rises sharply, forming a tornado.
