“…Hurricane Edna (September 6-11, 1954) followed a path similar to that of Carol. The area of strong winds and heavy rainfall extended into the Delaware River basin, but again the area escaped the major damage of the storm (Malkin and Holzworth, 1954;Davis, 1954).…”

The Delaware River basin is a diverse physiographic, hydrologic, and climatic region. The Delaware River serves as a major source of water for nearly 20 million people both in and outside the basin. Questions associated outside the variability of climate, the potential for climate change, and attendant implications for water resources and supply across this region in the coming decades require that there first be an appraisal of current climate conditions. To this end, graphs and maps for average monthly, seasonal, and annual values of temperature and precipitation across the basin during the period 1950-79 have been compiled in atlas form. Additional variables, including water budget terms, drought, cloud cover, hurricanes, and others have also been graphed and mapped. ' R" f^ FIGURE 11.

“…For instance, in 1954 two hurricanes, Carol and Edna, made landfall on Cape Cod, MA. and exhibited very similar movement characteristics insofar as they have been known as identical hurricanes in the meteorological literature in terms of their evolution (Malkin and Holzworth 1954). However, since their movement paths exhibit a distinctively different geometry (see Figure 1), these two hurricanes would not be extracted as similar using the available spatial movement similarity measures.…”

This paper describes a novel approach for finding similar trajectories, using trajectory segmentation based on movement parameters such as speed, acceleration, or direction. First, a segmentation technique is applied to decompose trajectories into a set of segments with homogeneous characteristics with respect to a particular movement parameter. Each segment is assigned to a movement parameter class, representing the behavior of the movement parameter. Accordingly, the segmentation procedure transforms a trajectory to a sequence of class labels, that is, a symbolic representation. A modified version of edit distance, called Normalized Weighted Edit Distance (NWED) is introduced as a similarity measure between different sequences. As an application, we demonstrate how the method can be employed to cluster trajectories. The performance of the approach is assessed in two case studies using real movement datasets from two different application domains, namely, North Atlantic Hurricane trajectories and GPS tracks of couriers in London. Three different experiments have been conducted that respond to different facets of the proposed techniques, and that compare our NWED measure to a related method.
