The compass rose map is a professional statistical map in meteorological science. It is used to count the frequency of wind direction and speed in a certain area over a period of time. It is divided into a wind direction rose map and a wind rose map. Wind speed rose chart. It gets its name because the graphic looks like a rose.
The wind rose diagram is an important part of public weather services and plays an important role in construction planning, environmental protection, production wind energy, fire protection, oil station design and marine climate. analysis and other areas.
The compass rose diagram reflects important information about the weather element wind. Using wind pollution theory can effectively guidecement urban planning and industrial development, and can also be used to analyze. the reasonable status of urban land use. Sexual or not.
The “Wind Rose” diagram determines the dominant wind direction at various locations:
Based on the percentage values of each wind direction and the speed of the wind in a certain area for many years and in a certain proportion, the pattern is usually represented by eight or sixteen cardinal directions.
Divide the 360° azimuth of the compass into 16 grids every 22.5°, and count the wind directions collected in real time in these 16 directions.
The wind direction shown on the rose diagram (i.e. the direction of the coming wind) refers to the direction from the outside to the center of the area.
The wind direction with the highest frequency is the dominant wind direction.
The mapThe compass rose is a professional statistical map in meteorological science. It is used to count the frequency of wind direction and speed in a certain area over a period of time. rose chart" and "wind speed rose chart"; because the charts are similar to Rose flower, hence its name. The wind rose chart is of great importance for fields related to urban planning, protection environment, wind power generation and other fields
The wind rose chart is divided into two types: the wind direction rose chart and the wind rose chart. wind speed roses A wind rose diagram represents the direction and frequency of wind direction. Wind direction frequency is the percentage of occurrences of different wind directions (16 wind directions were counted. ) for all observations over a certain period of time.frequency of wind occurrence in each direction, it is represented by the corresponding proportional length (i.e. the radius in the polar coordinate system), blowing from the outside towards the center according to the direction of the wind, and plotted on polar coordinates. diagram represented by 8 or 16 directions, then the ends in adjacent directions are connected by straight lines to form a closed polyline that looks like a rose, which is the wind direction rose diagram.
