3rd Annual Meeting of the Midwest Weather Working Group – Charlotte, NC – August 6, 2010 Conventional Approach
3rd Annual Meeting of the Midwest Weather Working Group – Charlotte, NC – August 6, 2010 Precipitation Estimates from RADAR Radar provides high spatial resolution. Reflectivity very sensitive to droplet diameter. Z = reflectivity factor N = refractivity D = droplet diameter
3rd Annual Meeting of the Midwest Weather Working Group – Charlotte, NC – August 6, 2010 Precipitation Estimates from RADAR Many sources of error in radar estimates: –Specific Reflectivity to Rain rate relationships used –Bright banding in the melting zone –Attenuation –Refraction of the radar beam –Precipitation from low-level clouds
3rd Annual Meeting of the Midwest Weather Working Group – Charlotte, NC – August 6, 2010
Solution (RADAR+ gages) MPE = Multi-sensor Precipitation Estimates –Digital precipitation estimates from NCEP at a resolution of km. –RADAR + surface gages –Best of both worlds!
