Upper and lower level PV-coupling associated with Alpine lee cyclogenesis
With the aid of six-hourly cross-section sets the interaction of upper and lower tropospheric potential vorticity maxima is investigated diagnostically for four Alpine lee cyclogenesis events. The cross-sections are derived from objective fine mesh analyses based on a corrected ALPEX-IIb SYNOP and R...

| description | With the aid of six-hourly cross-section sets the interaction of upper and lower tropospheric potential vorticity maxima is investigated diagnostically for four Alpine lee cyclogenesis events. The cross-sections are derived from objective fine mesh analyses based on a corrected ALPEX-IIb SYNOP and RAWIN data set. It is shown that phase coupling between upper and lower level regions of high potential vorticity values takes place in all cases, the lower level maximum being influenced or generated by Alpine orography. |
