RAL scientist Fei Chen has been named an AMS Fellow for 2013.  Fei specializes in modeling and observing interactions between the land surface and atmosphere, including the effects of wildfires and urban development. He joined UCAR's Visiting Scientist Programs in 1993, where he was based at NOAA's National Center for Environmental Prediction, and became an NCAR scientist in 1997. Fei has served on the graduate faculty of Purdue University and CU-Boulder and as visiting professor at the Chinese Academy of Meteorological Study.

RAL offers many different web sites where weather experts and the public alike can retrieve useful weather information.  Sites like the Aviation Digital Data Service  and RAL’s Real-Time Weather Data webpage provide unique platforms for users to visualize observations and forecast products (some of which are created by RAL’s own scientists and engineers).  A similar kind of site has just been become available – the Tropical Cyclone Guidance Project (TCGP) is now live at www.ral.ucar.edu/hurricanes/.

High Resolution Measurements of Cyclone Structure - the Profiling of Winter Storms Project

UCAR calendar - RAL - full listing - July 15, 2011 - 2:16pm

Foothills Lab Building 2, Room 1001, 10:00 a.m.

A two-year field campaign, Profiling of Winter Storms (PLOWS), was completed during the 2008-09 and 2009-10 winters to study the dynamic and microphysical processes that govern the spatial and temporal variability of precipitation in the warm frontal and the “wrap-around” deformation zone of continental extratropical cyclones over the central United States. During this seminar, I will review preliminary findings of PLOWS focusing on exceptionally high, ~15 meter horizontal resolution measurements of precipitation band structure. These data are derived from reflectivity and vertical air velocity measurements of the Wyoming Cloud Radar, a ground based X- Band vertically pointing Doppler radar, Profiler data and microphysical measurements from the NCAR/NSF C-130 aircraft. I will relate these measurements to the larger scale cyclone structure, and provide an interpretation of the dynamics of these bands consistent with the thermodynamic and kinematic measurements.

Several outstanding features of the data will be emphasized, including the common overrunning of upper tropospheric dry air over the warm front, the prevalence of elevated, upright, deep convection on the warm side of wrap-around region, the near-omnipresence of cloud-top convection, turbulence and supercooled water at very cold temperatures, the surprising lack of banded features on the cold side of the wrap around, and the complete misinterpretation of all of these features that one obtains from analysis of WSR-88D reflectivity measurements due to their poor vertical resolution and reduced sensitivity.

Aviation Tool Improves Safety, Sparks Innovation through User Feedback

Those who work in the aviation sector require a large amount of information to route, plan, and make decisions about air traffic control, aircraft, and airport operations. The sheer amount of data available to aviation personnel can seem overwhelming, as it includes pilot reports (PIREPS), aviation weather forecasts (TAFs and weather model data), satellite, radar, surface observations (METARs), official advisories, considerations of thunderstorm strength and location, and icing and turbulence information.

Economic cost of weather may total $485 billion in U.S.

Paved surfaces can foster build-up of polluted air

New research focusing on the Houston area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea.
