英文摘要: Abstract(#br)Analyzed results of the atmospheric wind speed and stable isotopic data (δ 18 O) in summer precipitation at Bangkok, Bombay, New Delhi, Kunming and Lhasa, the IAEA/WMO stations, indicate that δ 18 O in monsoon precipitation correlate positively to wind speed and that there exists a monsoonal vapor layer over these monsooncontrolled areas during monsoon seasons. The isotopic exchange happens between monsoon vapors and falling raindrops in the layer, resulting in this correlation between δ 18 O and wind speed. This suggests that wind speed is probably one of key factors affecting the δ 18 O variation besides air temperature and rainfall in the southwest monsoon domain.
