How to Determine Wind Direction?
Wind direction is measured in the number of ways with the help of different types of technologies designed for them. Some important devices that are used for the measurement of the wind direction are as follows

Wind Sock:
A type of the measuring device that was very famous among the people in the past but nowadays many other modern technologies came into being. Wind sock is the types of the cloth piece that is of conical shape with both ends open. Usually it is seen on the airports and some times in the technological plants. It placed on the rod like structure stand and this sock moves towards that side where the power of the wind is stronger.

Anemometer:
A modern device that is used to detect the direction of the wind is called as the anemometer. The common type of the anemometer that is used to determine the direction of the wind power is the cup shaped anemometer. It has four cup arranged on the rod one behind the other. When the wind blows they rotate. By counting the number of turns we can easily determine the direction

Wind Direction Sensors:
A type of the sensing technology that also do the same job of detection of the wind direction, basically wind direction sensors are the device that can calculate the direction of the wind accurately and valuably. Son these are some methods that are used to measure the direction of the wind energy. Some other multi purpose devices are also used that perform two functions i.e. detect the speed and the direction of the wind such as wind sensors, ultrasonic sensors etc. Some times wind vanes a4re also used to calculate the direction of the wind

Without Technology:
Wind direction is also measured in the absence of the technology. We can use the index finger for that purpose of detection, wet the finger and take finger in the upward direction. The side of the finger that feels cooling is the area from where the wind originates.

Wind direction Map:
The map that is required for the calculation and study the direction and speed of the wind energy is called as the wind direction map. Basically the main purpose of constructing the map is to save the country from different types of storms and predict the weather conditions related to the wind. Wind direction map also helpful for the wind power generating turbines because we can increase the output or efficiency of the electrical energy by studying the map.

Importance of Wind Direction:
Wind direction is an important component because with the help of wind direction we are able to construct the wind turbines facing that area of the wind origin. This really helps to increase the production of energy. There are lots of benefits of the wind direction or the measuring the wind direction, such as it is very helpful for the airports in determination of portion of the stronger wind.

Factors Affecting Wind Direction:
Some important factors are also affects the direction of the wind and are as follows

1. Rotation Earth surface
2. Pressure of the Wind
3. Friction
