The U.S. Great Plains is known for frequent hazardous convective weather and climate extremes. Across this region, climate change is expected to cause more severe droughts, more intense heavy rainfall events, and subsequently more flooding episodes. These potential changes in climate will adversely affect habitats, ecosystems, and landscapes as well as the fish and wildlife they support. Better understanding and simulation of regional precipitation can help natural resource managers mitigate and adapt to these adverse impacts. In this project, we aim to achieve a better precipitation downscaling in the Great Plains with the Weather Research and Forecast (WRF) model and use the high quality dynamic downscaling results...
These videos were recorded as part of an online interactive course titled "Managing for a Changing Climate", offered by the University of Oklahoma. The course is free and available worldwide for anyone with an internet connection through the Janux platform. Course content and assignments provide students with an integrative understanding of the climate system, the role of natural variability in the climate system, external drivers of climate change, and the implications of climactic shifts for natural and cultural resources. Resources managers, tribal environmental professionals, staff and students at other Climate Science Centers and Landscape Conservation Cooperatives, and members of the general public can participate...
Abstract (from http://link.springer.com/article/10.1007/s11069-016-2376-z): Drought is among the most insidious types of natural disasters and can have devastating economic and human health impacts. This research analyzes the relationship between two readily accessible drought indices—the Palmer Drought Severity Index (PDSI) and Palmer Hydrologic Drought Index (PHDI)—and the damage incurred by such droughts in terms of monetary loss, over the 1975–2010 time period on monthly basis, for five states in the south-central USA. Because drought damage in the Spatial Hazards Events and Losses Database for the United States (SHELDUS™) is reported at the county level, statistical downscaling techniques were used to estimate...
This project consisted of two principal components: (1) A climatological analysis of burn conditions (2) A forum to discuss fire risk and management practices The climatological study included seasonality and inter-annual variability and potential changes due to increasing temperatures. The regional forum engaged stakeholders in a discussion of the use of prescribed fire in a safe and effective manner.

Climate projections for the southern Great Plains, and elsewhere in the U.S., indicate that a hotter future with changes in precipitation amount and seasonality is to be expected. As plants become stressed from these changes, wildfire risk increases. One of the most valuable approaches to reducing the impacts of wildfires is fuel reduction through prescribed burns. Fuel reduction helps minimize the destruction of ecological communities, threats of future flooding, and extensive damages by lessening the intensity of future wildfires. Although safe burning practices can largely minimize the risks, prescribed burns may bring some degree of concern among practitioners. The real and perceived risks may include bodily...

The sky island forests of the southwestern United States are one of the most diverse temperate forest ecosystems in the world, providing key habitat for migrating and residential species alike. Black bear, bighorn sheep, mule deer, and wild turkey are just a few of the species found in these isolated mountain ecosystems that rise out of the desert landscape. However, recent droughts have crippled these ecosystems, causing significant tree death. Climate predictions suggest that this region will only face hotter and drier conditions in the future, potentially stressing these ecosystems even further. Simple models predict that vegetation will move to cooler and wetter locations in response to this warming. However,...
