In-flight icing
research has been conducted at RAP since 1989 and provides interesting
and challenging studies in cloud physics, remote sensing, and mesoscale
meteorology. The goal of this research is to develop more accurate
and timely diagnoses and forecasts of conditions leading to ice accretion
on aircraft during flight. The Current Icing Product (CIP) was accepted
as operational guidance by the FAA and NWS in 2002; in 2003 the Forecast
Icing Product (FIP) was accepted, as well as an experimental diagnosis
of icing in Alaska (CIP-AK). These algorithms have shown superior
skill in diagnosing and forecasting locations of in-flight icing conditions.
The diagnostic, or “real-time” versions combine observational
data with numerical weather model output using fuzzy logic techniques.
RAP's icing forecasting research also includes improvements to the MM5 and WRF models, including microphysical parameterizations to more accurately forecast cloud liquid, drizzle and rain. These improvements are transferred to operational use via the NOAA Forecasting Systems Laboratory and the National Centers for Environmental Prediction. RAP developed good working relationships with these organizations, which provide an effective means of technology transfer. Additionally, RAP scientists are leaders in model improvements working together with other divisions of NCAR and with the university community. Research Lead: Marcia Politovich
