As midlatitude cyclones supportive of ARs move eastward across this region, they interact with complex and formidable mountain ranges, which tend to result in cyclolysis and AR decay through rainout and other processes (Rutz et al.
First, time-series plots were utilized to determine which wind farm locations are in regions most sensitive to cyclogenesis, cyclone propagation, and cyclolysis. The member of the ensemble that produced the most significant changes to cyclone is chosen as the location in which the ensemble of wind farm sizes is run.
At the time of cyclolysis, at least 40% of all cyclones are still associated with a front.
To compare this multitude of tracks with different lifetimes, they are normalized to obtain a dimensionless track time with three fixed points: -1 at cyclogenesis, 0 at the time of minimum SLP, and +1 at cyclolysis (for details, see the appendix "Technical details--Normalizing cyclone track length").
During the decay phase, the fraction of late-front and initial-front cyclones with attendant fronts decreases to approximately 40% until cyclolysis for both categories (Fig.
Because of the difficulty in detecting occluded fronts, many decaying cyclones are likely associated with an occlusion at cyclolysis. However, with our approach, this fraction cannot be quantified.
At the time of cyclolysis, about 40% of all cyclones are still attended by a front.
Dots on these plots indicate the location of the surface low-pressure center every 24 h from 24-48 h before the start of an event until 24-48 h after its conclusion, unless cyclogenesis (cyclone development) occurred less than 24 h before event onset, or cyclolysis (cyclone dissipation) within 24 h of event termination.
Instead, we classified the case as one of either cyclogenesis or cyclolysis, regardless of where the low-pressure center was located in relation to the Archipelago.
Over all events, a greater number of cyclones entered the Archipelago (120) than exited (99) because cyclolysis was more common than cyclogenesis over the region.
