DTC Reference Configurations (WRF v3.3.1 and v3.4) (Jamie Wolff)

The WRFv3.3.1 & WRFv3.4 ARW PS:4.1.1.1.2.1.1 (with DA) configuration is based on the Air Force Weather Agency (AFWA) physics suite and was evaluated by the Developmental Tes...tbed Center (DTC) during the fall of 2012. A functionally similar environment to AFWA operations was utilized, where each configuration was initialized with a 6-hour "warm start" spin-up, including data assimilation. A Contiguous United States (CONUS) domain with 15-km grid spacing was employed for this test covering complex terrain, plains and coastal regions spanning from the Gulf of Mexico, north to Central Canada in order to capture diverse regional effects for worldwide comparability. This configuration is a general application configuration for mid-latitude forecasts.

The new DTC RCs include:

Polar bear hunting and migration 'hit by warming climate'
http://bit.ly/YoRx9x

"The migration patterns of the bears were governed by the conditions of the sea ice, and climate-induced changes to the rate and timing of sea ice melt and refreezing affected how long the bears spent on land."

"The longer the bears spend on land, the longer they have to go without their energy-rich seal food, with consequent impacts on their health and survival."

From heat wave to snowstorms, March goes to extremes
http://bit.ly/13c5hsJ

"The weather pattern that is responsible for this year's cold weather is unusual, even though it is not yielding extremely cold temperatures across the U.S. In fact, March is running near average for the lower 48 states. Still, after last year's nonexistent winter and downright summer-like spring, any cold and snow in March may seem like a shock to the system."

Crossing the Arctic by ship used to be a pipe dream. Now climate change is making it a reality: http://bit.ly/XU8DbS

Red lines indicate fastest available routes for moderately ice-hardened vessels (PC6); blue lines indicate fastest available routes for common open-water ships."
