Lightning Signature Assessment To Forecast Tornado Formation, Mary Snow, Richard Snow, Nicole Kufa

Publications

Recent research suggests that a maximum rate of lightning strikes occurs at least 15 to 20 minutes prior to tornado formation within a supercell storm. These maxima are associated with strengthening updrafts as they appear in radar measurements. An increase in lightning rates correlates with an increase of shear in the lower part of the storm. In combination with a strong updraft or downdraft, this shear can provide the ingredients for rotation and possibly a tornado. Polarity reversal of lightning around the time of tornado touchdown also has been examined. Thus, increasing lightning flash rates and reversal of lightning strike …

Multivariate Visualization And Analysis Of Photomapped Artifact Scatters, Nathan M. Craig, Aldenderfer Mark

Nathan M Craig

Simultaneous analysis of relationships between multiple artifact classes is required for characterization of many types of activity areas. This paper illustrates improved forms of multivariate visualization, spatial analysis and integration of experimental results that are possible with GIS based photomapping. Techniques are demonstrated through analysis of a hearth associated artifact scatter exposed during excavations of a Late Archaic pithouse at Jiskairumoko, Peru. A multivariate density raster is created and additive color visualization is used for simultaneous display of three artifact distributions. Performing unconstrained clustering in a GIS, space is classified by simultaneous relative density relationships between multiple object types.

Gis Modeling Of Desert Root Crop Maturation On The Mid-Columbia Plateau, Mary Michelle Phillips

All Master's Theses

The settlement patterns of the prehistoric inhabitants of the Columbia Plateau were choreographed to match the cadence of the seasons, with movements timed to efficiently utilize available resources. Desert roots, such as lomatium and bitterroot, provided a primary source of dietary nutrition, yet the ideal conditions for exploiting these plant resources coalesced for a very limited time in any one location. It was therefore necessary to possess an intimate knowledge of the plants' lifecycles in order to effectively plan gathering activities. In order to predict the growth patterns and maturation rates of these desert root crops, a GIS model was …
