2.4. Windrose for Average Wind Directions

Try these first

1. 1.

   What does a windrose diagram represent?

   Hint

   Think about what types of data about wind it visualizes.

2. 2.

   Which wind direction indicates that winds are coming from the north?

   Hint

   Consider which way the wind moves.

3. 3.

   What does a longer radius on a windrose signify?

   • Higher wind speed
   • More frequent calm winds
   • More consistent wind direction

   Hint

   Think about the meanings of longer lengths.

4. 4.

   True or False? Windrose diagrams are exclusively used for scientific research.

   • True
   • False

   Hint

   Consider the practical applications beyond research.

5. 5.

   Given an example windrose, identify which areas are most at risk for pollution dispersal from a fictitious chemical plant emitting a constant rate of pollutants.

   Hint

   Focus on which direction the wind blows most often.

6. 6.

   You have hourly wind data for a month; construct a detailed report summarizing the average wind speed and specific pollutant dispersal predictions.

   Hint

   Break down the data into manageable segments.
