Status: To verify
Type: Jet-core algorithm

Metric description

This is a jet-detection algorithm that defines the 'local wind maxima' "as those grid points surrounded, in the latitude-height plane, by points with a slower wind speed. The frequency of occurrence of local maxima above 30m/s during a certain period, expressed as the number of days per month in which wind maxima occurs at each grid point,". Then the algorithm: "selects grid points [...] as belonging to a STJ or a PFJ by defining latitude limits based on the latitudinal grid point distribution"

To do

Known problems

Other Notes

Builds on Koch et al 2006.
We remove the final step of the algorithm from the implementation in this module — which selects average jet-lat and velocity of the resulting local wind maxima points.

TODO:

• Still need to add PJ and STJ limits for seasons

"The latitude limits were defined using the zonal integral of the probability of jet cores occurrence (not shown)."
