Wind is measured based on which of the following parameters?

1. Humidity and temperature

2. Soil moisture content

3. Velocity, direction, and duration

4. Water retention capacity

The correct answer is: Velocity, direction, and duration

Wind is measured based on velocity, direction, and duration because these three parameters are essential in understanding how wind behaves in different environments. Velocity indicates not only how fast the wind is blowing but can also affect the rate of evaporation and cooling. Direction helps determine the source of the wind, which can influence local weather conditions and irrigation practices. Duration provides insight into how long a wind event lasts, which can affect soil moisture levels and plant transpiration rates. The other choices, while relevant to various aspects of environmental science, do not specifically pertain to wind measurement. Humidity and temperature are more related to atmospheric conditions affecting weather but do not directly measure wind. Soil moisture content and water retention capacity focus on the amount of water in the soil, which can be influenced by weather conditions but does not measure wind itself. Understanding wind through these three key parameters is crucial for effectively managing irrigation practices and optimizing landscape health.
