Long-term Trends in Winter Wind Speed and Frequency by Direction in Seoul

Bae, Jinho
This study investigated long-term linear trends in both wind speed and frequency of 16 wind directions during winter in
Seoul. Annual data on speed and frequency were analyzed by direction for Dec., Jan. and Feb. from 1963 to 2019. Six wind
directions, representing westerlies and northerlies, exhibited downward trends in speed: WNW and W in all three months,
WSW in Dec. and Jan., N and NNE in Dec., and NNW in Jan. WNW and W had the largest decreases. Overall speed
regardless of direction showed a downward trend for all three months. The weakening Siberian High was related to the decline
in wind speed. Long-term trends were found in frequency of occurrence as well downward trends were detected in ENE for
Dec. and Jan., and in WSW for Jan. Upward trends were observed for three northerlies, NNW, N and NNE: for NNE in
Dec. and Feb., and for N and NNW in Jan. The large downward trend in ENE winds led to a change in annual prevailing
wind direction.
