Mesoscale predictability of the "surprise" snowstorm of 24-25 January 2000
A mesoscale model is used here to investigate the possible sources of forecast error for the 24-25 January 2000 snowstorm along the east coast of the United States. The primary...- publication PDF

Can lidars assess wind plant blockage in simple terrain? A WRF-LES study
Wind plant blockage reduces wind velocity upstream of wind plants, reducing the power generated by turbines adjacent to the inflow, and potentially throughout the plant as well....- publication PDF
