Information Technology Approaches To Forest Management, Mary Snow, Richard Snow
Information Technology Approaches To Forest Management, Mary Snow, Richard Snow
Publications
The majority of the world’s forests occur where there is a dry season long enough to affect a seasonal change in the forest community. The seasonal forest may include evergreen, semi-deciduous, deciduous trees, or some combination of these. Local differences in soil or other site characteristics often determine which community persists. Since the seasonal forests exist where there is seasonal precipitation, the character of the forest is closely associated with the length of the rainy season. As the length of the rainy season decreases, the density of the canopy decreases. If the global climate system warms and prolonged drought gives …
Mitigating The Effects Of Climate Change With Wind Energy And Gis, Rachael Isphording, Richard Snow, Mary Snow
Mitigating The Effects Of Climate Change With Wind Energy And Gis, Rachael Isphording, Richard Snow, Mary Snow
Publications
The climate is changing, and humans are heavily exacerbating these changes. As the effects of climate change are being felt across the planet, scientists and policy makers are uniting to increase mitigation efforts and are researching renewable, clean energy sources to reduce the amount of greenhouse gas emissions released into the atmosphere during energy production. Of the different renewable energy technologies, wind energy is one of the most researched and implemented. Over the past twenty years, researchers have been applying Geographic Information Systems (GIS) to their climate change studies. GIS allows the user to spatially view, manipulate, and analyze data …
Lightning Signature Assessment To Forecast Tornado Formation, Mary Snow, Richard Snow, Nicole Kufa
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 …
