annual wind speed frequency distribution

wind frequency distribution

The evaporation in the experimental lakes area is thought to have taken place because of an increase in the frequency of wind and a rise in the wind velocities.

They will include sensors to measure, to fairly high standards, temperature, humidity, wind speed and direction, air pressure, precipitation occurrence and amounts.
