Figure 2 Time series of meteorological measurements: a wind speed V at the 32-, 63-, and 160-m heights; b relative humidity RH at the 63- and 100-m heights; c ¦£ ¦È for the 32-63- and 63-160-m height intervals; d R s ; and e R l . In a, the inset shows the wind roses at the individual heights. In c, the inset is a scatter plot to compare ¦£ ¦È . R s in d and R l in e are measurements at 140 m. The study period is 15-30 April 2012.
