Abstract:
The quasi-biennial oscillation (QBO) of wind and temperature in the tropical stratosphere is defined by zonal winds and temperature at Balboa, Canal Zone (9N), Singapore (1N), and Ascension Island (8S). Presented for these 3 stations are monthly, seasonal and annual values of zonal wind in knots (wind from the east is negative) and temperature in tenths of a degree Celsius (all temperature negative) at 50, 30 and 10 mb.
The 50 mb records begin in 1951 at Balboa, 1954 at Singapore and 1958 at Ascension. The 30 mb records begin in 1951 at Balboa, in 1954 at Singapore and in 1958 at Ascension. The 10 mb records begin in 1958 at Balboa, 1984 at Singapore and 1958 at Ascension. The data were obtained from the National Centers for Environmental Prediction of NOAA.
