What is the wind direction and how to measure it?

1, wind direction refers to the direction in which the wind blows. Generally, there are different determination methods. Mainly divided into oceans, continents and high altitudes. Wind direction can play an active role in people's life, production, factory buildings, agriculture, transportation, military and other fields.

2. One of the instruments for measuring wind direction is the wind vane, which is generally10-12m above the ground. If there is an obstacle nearby, its height should be at least 6 meters higher than the obstacle, and the short stick pointing north should face north. In which direction the wind arrow points, it means what direction the wind direction is at that time. There is also a rectangular wind pressure plate (800g in weight and 200g in weight) on the anemometer, and an arc frame with long and short teeth is installed next to the wind pressure plate. The number of long and short teeth that the wind pressure plate passes through indicates the wind force.
