The effect of the low-level jet on the poleward water vapour transport in the central region of South America
The low-level jet (LLJ) in the central region of South America is studied. This LLJ is generated by the daily cycle of convergence and divergence east of the Andes Mountains. We use the 1973-1974 radiosonde and pilot balloon data set from the upper air weather stations, Salta and Resistencia, in nor...
