Interannual Variability of Northern Hemisphere Storm Tracks in Coarse-Gridded Datasets
Figure 9
Cyclone track frequency climatology (shaded) for (a) NCEP1_5010 (JFM, AMJ, JAS, OND), (b) like (a) but for NCEP1_5801, and (c) like (a) but for ERA40_5801. Units: number of storms per winter for a 5° × 5° box. Cyclone track frequency climatology (shaded) for (d) like (a) but for Re27910, (e) like (a) but for NCEP1_7910, and (f) like (a) but for NCEP1_5078. Units: number of storms per winter for a 5° × 5° box.
