1. Determine the direction:
Wind direction refers to the direction of the wind. wind blowing from the outside towards the center of the area. The green line represents summer and the yellow line represents winter.
2. Determine the size:
The distance from the point on the polyline to the center of the circle indicates the frequency of wind blowing from that point toward the center of the circle. The solid line represents the permanent wind and the dotted line represents the summer monsoon.
3. Determine the frequency:
The closed figure formed by the solid line and the focus of the four coordinate lines represent the size of the wind. the greater the frequency of that wind direction.
The role of the compass rose map:
The compass rose map is a professional statistical map in meteorological science, used to count the frequency of direction and of the vwind speed in a certain area. for a period of time.
It constitutes an important part of public meteorological services and plays an important role in architectural planning, environmental protection, wind power generation, fire protection, station design oilfields, marine climate analysis and other fields. Reflecting the important information of the wind meteorological element, these data can be used to effectively guide urban planning and industrial layout using wind pollution theory. They can also be used to analyze the rationality of the current state of urban land use.
