Steenburgh, William James | Finescale orographic precipitation variability and gap-filling radar potential in Little Cottonwood Canyon, Utah | Finescale variations in orographic precipitation pose a major challenge for weather prediction, winter road maintenance, and avalanche forecasting and mitigation in mountainous regions. In this investigation, ground based X-band radar observations collected during intensive observing period 6 (IOP6)... | 2014-01-01 | |

Garrett, Timothy J. | Fall speed measurement and high-resolution multi-angle photography of hydrometeors in free fall | We describe here a new instrument for imaging hydrometeors in free fall. The Multi-Angle Snowflake Camera (MASC) captures high-resolution photographs of hydrometeors from three angles while simultaneously measuring their fall speed. Based on the stereoscopic photographs captured over the two months ... | 2012-01-01 | |

Garrett, Timothy J. | Observed influence of riming, temperature, and turbulence on the fallspeed of solid precipitation | Forecasts of the amount and geographic distribution of snow are highly sensitive to a model's parameterization of hydrometeor fallspeed. Riming is generally thought to lead to particles with a higher mass and terminal velocity. Yet models commonly assume that heavily rimed particles such as graupel ... | 2014-01-01 |
