SGP/EBBR/E15 - Wind Speed Cups Frozen

Freezing rain, snow, and below freezing conditions during 18-19 January
1995 caused the wind speed sensor cups to freeze in a stopped state at E15,
Ringwood, OK on 18 January 1995.  When temperatures rose to above freezing on
19 January, the ice thawed and the cups turned freely again.

Measurements affected by the stalled wind speed sensor include:

5 minute:  wind_s, res_ws

15 minute: wind_s

30 minute: wind_s, res_ws

• Wind speed arithmetic mean(wspd_arith_mean)
• Wind speed vector mean(wspd_vec_mean)
