摘要: [1] ECMWF ERA-40 reanalysis zonal winds are very close to tropical rocketsonde and rawinsonde (radiosonde & radar wind soundings) observations up 10 hPa. Above hPa differences increase, although the data provide a good representation of 2–3 The amplitudes quasi-biennial oscillation (QBO) semi-annual (SAO) derived from match We conclude that zonal-mean equatorial could be used, for most purposes, in place station observations.
