What are the examples of cyclones and anticyclones? Is the sandstorm a cyclone or an anticyclone?

Common examples of anticyclones are: high pressure, such as summer drought in the middle and lower reaches of the Yangtze River.

Neither. Sandstorms are neither cyclones nor anticyclones. It refers to the severe sandstorm weather phenomenon that strong winds blow up a lot of dust on the ground and throw it into the air, making the air particularly turbid and the horizontal visibility less than one kilometer.

Below, help you expand what is cyclone and anticyclone:

Cyclone refers to the large vortex in which the horizontal airflow rotates counterclockwise (clockwise) in the northern (southern) hemisphere atmosphere. At the same height, the air pressure in the center of the cyclone is lower than that around it, which is also called low pressure. It appears as a low-pressure area surrounded by closed isobars on the contour map, and a low-value area surrounded by closed isobars on the contour map.

Anti-cyclone refers to the horizontal air vortex with the central air pressure higher than the surrounding air pressure, and it is also the high pressure in the air pressure system. The anticyclone in the northern hemisphere, the horizontal airflow in the lower layer diverges clockwise, and the anticyclone in the southern hemisphere diverges counterclockwise.

The horizontal scale of anticyclone is greater than that of cyclone. For example, the Mongolian-Siberian high in winter occupies 1/4 of Eurasia.

The air pressure in the center of each anticyclone is generally around 1020 ~ 1060 HPA, and the highest air pressure recorded is110/.6 HPA. The wind speed in the anticyclone is small, and the maximum wind speed on the ground is only 20 ~ 30m/s, and the wind force in the central area is weak. Controlled by anticyclone, the weather is sunny most of the time.
