Identification and global climatology of upper-level troughs at low latitudes

A new algorithm has been developed to identify upper-level troughs propagating from the extratropics into low latitudes. In contrast to previous studies the identification algorithm analyzes vertical averages of potential vorticity (VAPV) in the 400-100 hPa layer. This way the detection is less sens...
