How do you convert wind direction to degrees?
Abbreviations are defined below with compass point ranges for each of the wind direction categories:
- N = North (349 – 011 degrees)
- NNE = North-Northeast (012-033 degrees)
- NE = Northeast (034-056 degrees)
- ENE = East-Northeast (057-078 degrees)
- E = East (079-101 degrees)
- ESE = East-Southeast (102-123 degrees)
How do you read wind direction Degrees?
The truth is that wind direction can also be presented in azimuth degrees, i.e., in a numerical measure that moves around the Rose of the Winds in a clockwise circle from 0 degrees (N) to 360 degrees (N). So, if north represents 0 degrees, then east is 90 degrees, south is 180 degrees, and west sits at 270 degrees.
How do you read a wind rose on a route chart?
Wind Rose on Routing Charts Wind roses are shown in red on routing charts, in the form a circle having arrows pointing radially towards center. The arrows fly with the wind, and this fact provides the direction. The length of the arrow indicates the percentage frequency of occurrence on the scale provided on the chart.
What is WNW direction?
The eight half-winds are the direction points obtained by bisecting the angles between the principal winds. The half-winds are north-northeast (NNE), east-northeast (ENE), east-southeast (ESE), south-southeast (SSE), south-southwest (SSW), west-southwest (WSW), west-northwest (WNW) and north-northwest (NNW).
What direction is 180 degrees?
Ninety degrees corresponds to east, 180 degrees is south, 270 degrees is west, and 360 degrees and 0 degrees mark north.
What wind direction is 90 degrees?
Wind direction is expressed as the direction from which the wind originates. For example, a wind direction of East, or 90 degrees, means the wind blowing from the East to the West.
How do you read a weather Rose?
The wind rose located in the top right corner of each data map shows the general wind direction and speed for each sampling period. The circular format of the wind rose shows the direction the winds blew from and the length of each “spoke” around the circle shows how often the wind blew from that direction.
Why is the direction of wind?
Blowing from high to low pressure, air always attempts to balance out the pressure levels. A high-pressure system next to a low-pressure system will cause wind direction to flow clockwise and outward toward a low-pressure system. The low-pressure system is what causes air direction to flow counterclockwise and inward.
How many directions can you draw a wind rose?
The simple on line tool available in this web site allows to create wind roses with 16 directions, each one representing an arc 22.5 degrees wide. The first direction is centred on North (i.e. 0 degree), and the last one on NNW (i.e. 337.5 degree).
How to generate wind rose diagrams?

What is a wind rose?
Wind roses are graphical charts that characterize the speed and direction of winds at a location. Presented in a circular format, the length of each “spoke” around the circle indicates the amount of time that the wind blows from a particular direction. Colors along the spokes indicate categories of wind speed.
What is the direction of the Wind in the map?
The first direction is centred on North (i.e. 0 degree), and the last one on NNW (i.e. 337.5 degree). As usual, the wind direction represents the direction from which the wind blows. The colours of the wind speed classes cannot be modified, they are red, yellow, green, cyan, and blue.
