What is the symbol for weather wind?

The wind symbol is a wind pole with tail feathers, as shown below.

In weather forecasts, we often hear terms such as "North wind level 4 to 5", and the wind force referred to at this time is the average wind force; for example, we hear "gust level 7" and the like. In terms of wind gust, it refers to the wind speed that changes from high to low, and the wind force at this time refers to the strong wind force.

Wind is caused by differences in air pressure

When air pressure differences exist, air will move from high-pressure areas to low-pressure areas, resulting in winds with different wind speeds. On a rotating planet, outside the equator, the flow of air will be deflected by the Coriolis force.

Globally, the two main drivers of large-scale winds (atmospheric circulation) are the difference in heating between the equator and the poles (the difference in absorption of solar energy that causes buoyancy) and the rotation of the planet.

At high altitudes beyond the equator and not affected by ground friction, large-scale winds tend to reach geostrophic equilibrium. At the Earth's surface, friction causes winds to gradually slow down. Surface friction also pushes more wind into low-pressure areas.
